he famous line of Robert Frost – …And miles to go… – is quite significant
in the current context of India’s economy. Although the country’s
economic progress in recent years has brought about certain changes
in basic infrastructure, there is a clear and critical need for its further
expansion in a fast-phased manner considering the demand dynamics of a burgeoning
populace. Like any other sector, the fate of plastics industry also factors this. Moreover,
there is an ever growing emphasis on sustainable processes and technologies that will
not only meet today’s needs, but also have adequate provisions for tomorrow.
In this scenario, the much-needed scale-up in India can be achieved if both the
public and private sectors join hands through Public Private Partnership (PPP) rather
than trying to individually tackle this imminent challenge of enormous proportion.
Although PPP appears to be a win-win situation for all stakeholders, the key to success
in such projects lies in effectively managing the interests of public and
private sectors across different roles. Also, considering PPP experience
in different sectors, some key implementation aspects of PPP need
to be well-defined and communicated to all concerned parties before
initiating a PPP project.
With fast evolving socio-economic landscapes of India and the
resultant demand drivers pertaining to numerous industrial and
consumer segments, the role of the plastics industry, especially in
devising an optimum life-cycle strategy involving virgin resins,
plastic products and recycled resins, cannot be emphasised
more. Further, since this has a direct bearing on three
key stakeholders – consumers, industrial producers and the
government – applying a PPP concept here seems to have
a promising potential. For a sustainable, standardised and
scalable PPP model in the country, there is a need to have
a futuristic as well as facilitating framework in place, with a
clear mandate of three Ps – people, processes and performance.
Although there is an air of optimism surrounding PPPs in
the country at the moment, a comprehensive analysis calls for its
judicious use in a customised manner as per the need of the particular
sector and circumstances. This will entail clearly demarcating specific
roles, rights and responsibilities; setting precise standards; providing
training to various stakeholders; and fine-tuning the process on a
regular basis to enhance the efficacy of the system. Only time will tell
whether the proposed PPP model will usher in a new growth paradigm
for the plastics industry.

WL Plastics to build new polyethylene pipe plantPolyethylene pipe extruder WL Plastics
Corp plans to build a plant, thus bringing
in jobs to Rapid City, South Dakota USA,
attracted by the Williston Basin oil boom in
Montana and North & South Dakota. Mike
Dahl, Director, WL Plastics, said, “The
company has an option to buy land. The
plant will have a rail spur. We are currently
in the process of designing, and will move
ahead after completing our design and
finalising our budget.”
“By end of summer, we will have a fully
articulated budget. Not only will this create
new jobs, but also enable us to position
ourselves better in the market. This is part of
our long-term market strategy,” added Dahl.
Rapid City would be the seventh plant for
WL Plastics based in Casper, Wyoming,
which has focussed on the energy sector and
grown rapidly besides new sources of oil
& natural gas in the US and Canada. The
company’s sixth plant opened in June, in

Mamata Machinery to start operations at its new facility Gujarat-based Mamata Machinery Pvt
Ltd is in the process of shifting its
operations from the present facility in
Vatva to the new facility in Changodar in
Ahmedabad. The new facility has a total
land area of 36,000 sq m and is much
larger than the previous facility.
Abhijit Deshmukh, Senior Sales
Manager, Mamata Machinery Pvt Ltd,
noted, “The new facility was built
in eight months. The shifting is
being done and the new facility will
be fully operational in few weeks
f rom now. The major reason behind
this shifting of operations to the new
facility was that the old facility was
small and unable to handle large
productions.”
The company specialises in bag-
making and pouch-making machines.
It makes machines for industrial bags
used for packing salt, detergent, shirt,
stationery items, etc, and pouches for
packing hand wash, shampoo, etc, which
utilise sustainable films and not laminates.

Crude oil prices adversely affect polymer prices
According to a study conducted
by The Associated Chambers of
Commerce and Industry of India
(ASSOCHAM), the international
oil prices and Rupee exchange
rate have been moving in
opposite directions, thus denying
Indian polymer importers the
benefit of drop in rates of crude
oil in the international market.
The study, which analysed the
dynamics of oil prices and India’s
import bill during April 2009-
May 2012, revealed that with
the devaluation of the Indian
Rupee and increase in global crude
oil prices, Indian polymer buyers
have been facing a rise in their
import bills. Yet the oil import
bill in rupee terms largely shows
an increasing trend, which has not
benefited polymer importers on
their prices.
D S Rawat, Secretary General,
ASSOCHAM, said, “The benefits
of lower international prices were
either offset by a faster depreciating
Rupee or a slower appreciating
Rupee, and this could not offset
the negative effect of a sharper rise
in international crude oil prices,
thereby resulting in a higher import
bill. This has a direct impact on the
plastics industry, which is heavily
dependent on crude oil imports.”
Further, the crude oil imports and
its impact on government finances
are dependent on import quantity,
international price of crude oil and
the exchange rate.Anwesh Koley

Sixth symposium for Plastics Processing a huge success
With over 200 visitors and 18 presentations
on ‘New Trends in the plastics industry’, the
sixth Plastics Processing conference held
recently by the KREYENBORG Group in
Muenster, Westphalia, was a major success. The
presenters in the conference included polymer
giants from across the globe. The attendees
received considerable information on the latest
happenings in the polymer industry.
Jörg Auffermann from BASF presented the
fully biodegradable product Ecovio®, which is
made of renewable raw materials, and Ecoflex®,
the familiar BASF biodegradable plastics based
on petrochemicals. Innovations in underwater
pelletising technology were showcased by Frank
Brauer from BKG Bruckmann and Kreyenborg
Granuliertechnik GmbH.
In an interesting presentation,
Dr Thomas Grimm-Bosbach from Seebach
GmbH explained that the polymer industry
is driven by cost pressure (higher throughput,
longer lifetime) and required product quality
through finer filtration of optical quality. He
opined that modern melt filters must fulfill
these requirements. The optimisation of melt
filtration is done by enlarging the filter area,
using the smallest possible unit, adjusting the
filter medium to the customer process as well as
choosing the right filtration technology.

order to meet increasingly challenging
requirements and accommodate
both market-specific and internal
developments, Romeo Corvaglia,
Founder, Proprietor and Chairman
of Board of Directors, Corvaglia
Group, had begun restructuring and
remodeling process in 2011, which is
now complete.
Thomas Marder, who had been
on Board of Directors of Corvaglia
Holding since 2009, took on the overall
responsibility for the Corvaglia Group
as Chief Executive Officer (CEO)
in July 2011. With a successful track
record of managing several international
technology companies employing up
to 1,100 staff, he has considerable
experience of designing effective and
efficient processes. This responsibility
was previously managed by Corvaglia,
who will gradually step back from
operational matters. As Chairman of

State boost for SME community In order to reinforce the role of Small and Medium Enterprises (SMEs) in the industrial growth story, the Small and Medium Development Chamber of India (SME Chamber of India) and Maharashtra Industrial and Economic Development Association (MIEDA) had recently organised the annual ‘Maharashtra SME Summit’ in Mumbai. In his inaugural speech, Sachin Ahir, Minister of State for Industry, said, “Though the State receives large foreign direct investment and investment in various sectors, the SME community can benefit by getting emerging business opportunities from various projects. The economic slowdown has adversely affected this sector. Thus, this is the perfect time for the government and banking sector to extend required support to the SME sector to survive this uncertainty.
Government of Maharashtra is in the process of bringing out the industrial policy to give priority to the SME sector.”
Also present at the event was J K Dadoo, Joint Secretary, Department of Commerce, Ministry of Commerce and Industry, Government of India. He highlighted various benefits of antidumping law. Defining the law, he explained that it was structured to protect the domestic industry from uncontrolled flow of foreign goods at prices lower than the domestic goods.
Sumitomo Chemical consolidates its position in India With a presence for over 14 years in India, Sumitomo Chemical enjoys a position of leadership in the Indian Polymethyl Methacrylate (PMMA) market. In order to consolidate and grow further, Sumitomo Chemical– Singapore has aligned with J P Plaschem, Mumbai. J P Group presents a one-stop-shop solution for its customers, thus providing a significant value addition to the business of SUMIPEX PMMA, the acrylic resin from Sumitomo. SUMIPEX PMMA, from Sumitomo Chemical - Japan, is produced by the Sumitomo technology at their wholly owned subsidiary Sumitomo Chemical Singapore at the Singapore plant.
“There is tremendous potential for acrylic in cosmetic packaging. Big companies such as Revlon, Maybelline and ELLE 18, use acrylic for their cosmetic packaging. Since most of these companies have entered India, they will slowly increase the use of acrylic in their product packing. At present, Indian companies such as Lakme and Emami have also begun using small quantities of acrylic in their packaging. This will ensure better aesthetics and be more expensive than normal polymer packaging. It is environmentally sustainable, as it is a recyclable polymer. Also, since the usage is not expected to reach the proportions of Polyethylene or Polypropylene (PE/PP), this will not be harmful in the least,” said M A Bala Gopal, Head-International Business, J P Group.

Kreyenborg group presents innovative technology at ACHEMA 2012
Filtering and conveying of plastic melt, innovative valve technology and pelletising & infrared drying technology are the specialties of the KREYENBORG Group. ACHEMA 2012, which is to be held on June 18-22, 2012, at Franfurt, Germany, will focus on efficient systems. An interesting point for polymer producers is the increasing
trend to replace large area filters in polymer lines by screen changers. This results in numerous advantages, eg, quick change of the filter media or the short residence time of the material in the screen changer. Overall, screen changers can considerably increase the profitability of the complex line.
The new KREYENBORG V-type screen changer with power backflush technology provides for a particularly profitable filtration. Integrated into sensitive extrusion applications, it permits the production of most high-quality products out of polluted input material. Its inimitable backflush system thereby ensures a high screen lifetime and minimal backflush loss.

Breakthrough for Indian scientists in degradable plastics A three-member team of scientists f rom the Institute
of Chemical Technology, Mumbai, have developed an
oxyodegradable polymer by combining plastic granules with a
catalyst, which enables the plastics to break down to smaller
chains under direct sunlight. Although this technology has been
available since quite some time, what differentiates the new
approach is that these smaller chains are eventually consumed
by bacteria present in the soil.
The catalyst works on any type of plastics and facilitates its
oxydegradation, ensuring that it does not pose as a health hazard
or threat to the environment in the long term.
“As the molecular weight declines due to oxydegradation,
this gives the microorganisms access to carbon and hydrogen,
allowing plastics to function as a nutrient for fungi and bacterial,
thus enabling complete degradation,” said R N Jagtap, Head -
Department of Polymer & Surface Engineering, Institute of
Chemical Technology. The efforts made by the research team
for nearly half a decade in a tenacious process of discovery have
finally yielded results. Moreover, the metallic catalysts are not
derived from toxic heavy metals, and the team is in the process
of acquiring a patent for the technology that could revolutionise
how plastics is looked upon at present.

New SMP developed from TPU A new Shape Memory Polymer (SMP)
– Desmopan DP 2795A SMP, has
been developed using Thermoplastic
Polyurethane (TPU) by Bayer
MaterialScience and BAM Federal
Institute for Materials Research and
Testing. Components made of this
innovative plastics can be reshaped
and fixed temporarily when heated
to a specific temperature, called
the switching temperature, and the
parts recover to their original shape
without any changes. The switching
temperature of the innovative SMP
is about 40°C. Other benefits offered by
this plastic material include excellent
chemical and abrasion resistance and
flexibility.
Potential applications of Desmopan
DP 2795A SMP include repair of
damaged components by using shrink
tubing, packaging, self-loosening
screws, artificial muscles, remote
temperature sensors and hair dryers.
The TPU material is ideal for food
contact applications and can also be

New locked blow and fill system KHS Corpoplast, Germany, has
introduced its blocked blow moulding
system, a combination blower, filler
and capper unit that can be used in
Polyethylene Terephthalate (PET)
applications. The InnoPET BloFill
blocked system is designed to increase
efficiency and cut costs by filling
in-line after blowing.
The system connects the blower
directly to the filler and capper
unit, cutting out the air conveyer,
bottle rinser and other components.
Instead, a multi-functional star wheel
conveys the bottles from blower to
filler by way of a transfer block. The
block separates the dry blowmoulder
from the wet filler and includes an
airlock with constant air flow. The
base system can be used for water
or other non-carbonated soft drinks
and can make up to 72,000 bottles
per hour. With some modification,
the system can also be used for
carbonated beverage applications and
hot-fill applications at 185-190°F
(85-88°C).
Light guide panels by Arburg
Arburg has developed a hydraulic
compression moulding machine designed
for a 0.5-mm-thick optical application. The
light guide panels are moulded with a thin
optical panel intended for use in tablets and
Thin Film Transistor (TFT) screens, using
Light-Emitting Diode (LED) lighting; also,
the mould cavity does not close completely.
The hydraulic Allrounder 630 S has a
clamping force of 250 tonne and operates
with a two-cavity mould. It maintains a
1-mm gap until the last 50 millisecond of
the process. The mould, in turn, must be
designed so that the cavity is sealed, even
in the partially open state. This process
helps reduce shrinkage and deformation
and can accommodate precise moulding
specifications. The light guide panel features
nearly imperceptible ridging and changes in
thickness at the edges, designed to ‘guide’
LED light from the edges of the panel.
Most tablet panels are lit from behind, but
the light guide panel can be lit from the
edges and maintain even brightness across
the entire surface of the panel.
Sim-pull closures foil tamperers Two all-in-one foil closure solutions
for the food industry have been
launched through a licence agreement
between Dorking-based Bapco
Closures and Aptar. The new Sim-
pull and Trilogy closures both feature
a proprietary Bonded Aluminium-
to-Plastic (BAP) technology, which
claims to provide ease of opening,
built-in tamper-proofing and
excellent seal integrity.
The Sim-pull solution has a flip-
lid design, allowing consumers to
open lids with one hand, according
to Bapco. It is designed for a
diverse range of contents including
snack and granular products such
as nuts, crackers, baking agents and
sweeteners. A variety of ring-pull
configurations enable manufacturers
to tailor the closure to their particular
product specifications. The Trilogy is
a two-piece spout and closure design.
These new solutions meet the
growing demand for re-sealable
closures for on-the-go and at-home
eating. These are perfect for
occasions when customers want
to consume a single portion of food
and save the rest for later. Because
of their ease of opening feature,
Sim-pull and Trilogy are particularly
suitable for elderly consumers
and children.
New LVT eliminates problems in extrusion blow moulding of polyolefinsThe new Liquid Vehicle Technology
(LVT) developed by Clariant
Masterbatches has the capability to
eliminate many of the problems that
have prevented wider use of liquid
colour and additive concentrates in
extrusion blow moulding of polyolefins
(high- and low-density polyethylene
and polypropylene).
Initial testing in monolayer
containers demonstrates that these
highly compatible systems allow for
higher pigment loadings and lower
usage rates, while practically eliminating
past challenges related to screw slippage.
Improved resin compatibility results
in stronger weld lines in the finished
container as evidenced by the scores of
standard burst and compression-loading
tests. The new masterbatches use a
liquid vehicle system that incorporates
suspension aids, and binders have
been incorporated into the new LVT
masterbatches to allow for higher
pigment loadings and, in most cases,
lower usage rates.
Additional components enhance
flow and make for dramatically
faster colour changes. The benefits
of this technology include improved
weld-line strength, better processing
characteristics, faster colour changes
and greater productivity.

“Energy saving is possible throughout the entire system by selecting the right equipment”
40 Modern Plastics & Polymers | July 2012
IN CONVERSATION WITH: Nandakumar T
Nandakumar T
What are the current growth dynamics for the plastics industry in India?Indian plastics processors are innovative,
dynamic and demanding. They require
technological leadership, together with
outstanding service and short response
times. With this competitive spirit,
the Indian plastics market has grown
consistently over the last few years.
But, the need of the hour is innovative
automation and robotic solutions to keep
pace with global developments. Most
processors are aware that resins represent
a significant percentage of their overall
part-cost, yet they often do not realise the
true cost savings available to them from
efficient handling and control of resins.
Material handling is an area where
many processors are now looking at in
order to reduce their input costs and
improve overall operation without
making a significant capital investment.
Simplification of controls and operation
of equipment is critical for processors
facing a shortage of skilled personnel.
As the Indian plastics industry seeks
energy-efficient equipment to reduce
manufacturing costs, Wittmann
Battenfeld is making a great impact in
delivering low-consumption, high-output
solutions.
How would you describe the journey of Wittmann Battenfeld in India? Wittmann is dedicated to robotic and
automation technology for the Indian
plastics processing machinery market.
After its formal incorporation in
December 2006, Wittmann India was
renamed as Wittmann Battenfeld India
Pvt Ltd, after just one and a half year,
reflecting our broad sales & service
synergy with Wittmann’s acquisition
of Battenfeld in April 2008. Since
then, the Indian company has enjoyed
uninterrupted growth. This does not only
reflect in our marketshare, but also in the
growth of our team in India.
Completing five years in India, we
continue our journey towards being
a complete solutions provider for the
Indian plastics industry. This being our
core strength, we are developing better
solutions for this challenging market to
further strengthen our position.
How can machinery makers overcome cost-quality pressures in India?Not only the size, but requirements for
quality and efficiency are also growing
in the Indian plastics market. At present,
the drive for leading technology is
becoming a major decision factor. Speed,
consistency and energy-efficiency are
the uncontested requirements for every
production unit. As Indian manufacturers
recognise the value of these advantages in
the domestic and export market, quality
scores over price as a key concern of
the globally competitive manufacturer.
Wittmann does not compromise on
quality irrespective of the price factor. Our
cost-competitive solutions are designed
as per manufacturers’ specifications. We
maintain a standard quality policy, thus
strengthening our base in India. We
believe in technology consistency and
transparency across the world through all
our subsidiaries.
What are your current focus areas and future strategy?We are currently the third largest player
in the plastics processing machinery
automation space in terms of market
value. We are expanding our presence in
India through a larger shop floor, which
is likely to begin operations by mid-2012.
We expect a 40-45 per cent jump in
revenue through a well-defined sales and
service network across India. Industry-
wise we are focussing on medical
devices, automotives and white goods
manufacturing. Due to high growth
rates in these industries, and the need
for precision & high productivity, we are
witnessing a rapid shift from conventional
manufacturing to automation & robotics.
As a global player in the plastics
machinery space, Wittmann Battenfeld
is present in all major markets of the
world. But, the Indian subsidiary has also
exported to countries like Uzbekistan,
South East Asia and South Africa.
We remain committed to the Indian
market and are currently establishing a
manless operation factory with one of our
Indian clients.
What are Wittmann’s R&D initiatives in India and globally?We believe in lean production and global
technology to supply the plastics processor
with the best possible technology
at competitive prices. Wittmann’s
Research and Development (R&D) has
increasingly centred on environmental
aspects, with innovations to reduce energy
& oil consumption and noise level by
establishing a true modular concept. Once
these early concepts are decided upon,
we develop the prototype and study its
feasibility in an increasingly competitive
market. Wittmann’s R&D also focusses
on simplification of controls to develop
easy-to-use, open machines thereby
simplifying the shop floor for the operator
and manufacturer. In order to maximise
equipment output and ensure standards
of quality & consistency, processors are
relying more on automation and reducing
dependence on skilled personnel.
When we launched operations
in India, our priority was to adapt
Wittmann’s solutions to Indian conditions
of temperature, humidity and power
supply. Currently, many of the software
R&D projects at the Wittmann tech
centre in Vienna are being developed as
per Indian specifications.
How important is sustainability for plastics processing machinery?Machinery manufacturers play a pivotal role
in making the plastics industry competitive
on the sustainability front. Energy saving is
possible across the entire system by selecting
the right equipment and dimensioning it
as per product analysis, measurements and
readjustment of the process. Wittmann
supports this cause by developing energy-
efficient automation solutions. This needs
creating a culture of energy consciousness.
We have done this by putting the
star rating stickers on our equipment.
We are the only company in the
Indian plastics industry to have this energy
rating sticker.

SPECIAL FOCUS: Thermoforming
With the rapidly rising
price of commodity
polymers, the scenario
in the plastics
market has undergone a change. Many
plastics processors have entered into
thermoforming through acquisition
of companies in this industry in order
to remain a competitive supplier of
containers, particularly to the dairy
market. The reason is orientation strength,
which is achieved by thermoforming
as it is done below the melting point
of the polymer, particularly with
Polypropylene (PP).
Owing to these benefits, it is possible
to produce containers such as those used
for dairy products with much thinner
walls, but having the same compression
strength as their injection moulded
equivalents. S C Dutta, Managing
Director, Shalimar Thermoforming Pvt
Ltd, says, “The thermoforming industry
is flourishing in India. The process finds
wide applications in the day-to-day life,
eg, catering items, food trays/packs, cups
and glasses, beverage containers, bakery
packaging and large industry applications.”
Preference for the processThe customer today demands light-
weight packaging for most of his/her daily
requirements. Thermoforming offers the
advantage of manufacturing thin-walled
products, which help in weight reduction.
Therefore, more and more entrepreneurs
are entering the thermoforming process
industry. An important issue here is that
entrepreneurs consciously manufacture
products from quality/virgin plastics/
polymer to meet the environment norms.
Plastics find various applications in
every day usage. However, in manufacturing
of packaging material or containers, trays
and boxes, PP and Polystyrene (PS) are
fast gaining ground in terms of usage,
while thermoforming is the most widely
used technique for making finished
products. The ongoing development of
new materials, equipment and tooling
technology has enabled thermoforming
to find applications in areas that formerly
utilised paperboard, glass, metal, wood,
Expanded Polystyrene (EPS) foam, etc.
“Compared to other plastics processing
techniques (injection moulding, blow
moulding), thermoforming offers low-
cost tooling, fast, inexpensive prototyping,
shorter production lead times, custom
designs that can be easily modified, thin-
The ability to produce light-weight, cost-effective plastic products without compromising the tensile strength makes thermoforming one of the most sought-after methods and a viable option for plastics processors. Anwesh Koley looks into the latest technologies used in this process to offer high-quality end products.

Thermoforming
walled products, demand flexibility and
exceptionally large part capabilities. Thus,
thermoforming facilitates ideas to reality,”
says Dutta.
Application areas Thermoforming is a secondary shaping
process, the primary process being one
that produces the sheet or film. Only
thermoplastics can be thermoformed,
since extruded sheets of thermosetting
or elastomeric polymers are cross-linked
and cannot be softened by reheating.
Common thermoforming plastics are
PS, cellulose acetate and cellulose acetate
butyrate, Acrylonitrile-Butadiene-Styrene
(ABS), Polyvinyl Chloride (PVC), acrylic
(polymethylmethacrylate), polyethylene
and PP.
Mass production with thermoforming
operations is done in the packaging
industry. The starting sheet or film is
rapidly fed through a heating chamber,
which is mechanically formed into the
desired shape. The operations are often
designed to produce multiple parts
with each stroke of the press by using
moulds with multiple punches and
cavities. “In some cases, the extrusion
machine that produces the sheet or film
is located directly upstream from the
thermoforming process, eliminating the
need to reheat the plastics. For optimum
efficiency, the filling process to put the
consumable food item into the container
is placed immediately downstream from
thermoforming,” says Dutta.
Thin film packaging items that
are mass produced by thermoforming
include blister and skin packs. These
offer an attractive way to display certain
commodity products such as cosmetics,
toiletries, small tools and fasteners (nails,
screws, etc). Thermoforming applications
include large parts that can be produced
from thicker sheet stock, eg, covers for
business machines, boat hulls, shower
stalls, diffusers for lights, advertising
displays and signs, bathtubs, toys, etc.
The injection moulding process is
often compared with thermoforming.
However, thermoforming enjoys certain
advantages, which make it the preferred
choice in many applications. Injection
moulding has its limitations when it
comes to size of product and cost of
tooling. A typical injection mould tool
will cost roughly 33 per cent more than
a similar thermoformed tool, and the
margin increases as the parts become
larger. “Injection moulding does not have
a good prototype process, as typically
Stereolithography (SLA) or Selective
Laser Sintering (SLS) parts that are
used for prototyping, which offer limited
comparisons to the actual final product,
can be expensive, and are not of the same
material with which the final product
is made. Thermoforming, on the other
hand, utilises a prototype tool made from
wood or epoxy that can be used to create
several finished parts of the product and
formed from the same material with
which the final product is made,” adds
Dutta. Therefore, many possible design
or fit issues can be caught before going
to production tooling, thus saving time
and money.
Areas to work onThermoforming enjoys many advantages,
but the industry needs to understand
certain fundamental requirements to
ensure steady growth. “An important
concern is that thermoforming
machinery, which is expensive since it is
monopolised by only few manufacturers
who are concerned only up to supplies
and have not considered developing the
skilled workforce to facilitate growth
of the entrepreneurs. The after-sales
service is also not up to the mark, which
should be taken care of by machinery
manufacturers,” believes Dutta. Also,
remote areas and states have difficulties
in terms of technical know-how, logistics,
with delays in after-sales service support,
thus adversely affecting the industry. “A
proper advisory should be issued to the
manufacturers that it is in the interest
of the country to promote and help the
best as well as most efficient utilisation
of machinery available in the country to
avoid wastage of resources,” adds Dutta.
Roadblocks aheadThe key challenge for the thermoforming
sector in India is that the used disposable
plastic and polymer articles are not properly
managed and collected for recycling to
avoid hazardous effects on earth. “The
government, civil society and industry
together must make efforts to create
awareness and pass an ordinance to ensure
scientific disposal of used plastics/polymers
for ensuring environment safety, otherwise
thermoforming sector cannot reach the
desired heights in the coming years, which
would be a huge loss for both the industry
and the society,” opines Dutta.

thermoforming technology
depends on var ied
applications that the process
enjoys. Packaging is an important
area where thermoforming is used.
Thermoformed packaging refers to
a type of retail packaging that uses
thermoforming technology. In this
process, a special type of plastics is
melted to liquid form and frozen to a
brittle, almost glass-like state. This type
of thermoformed packaging is preferred
for various applications and industries,
such as dairy and food packaging, as
well as cold beverage cups.
The thermoforming technology
provides cost-efficiency and high quality
of polymers used in packaging. V Vikram,
Proprietor, Sealers India Agencies, says,
“Thermoformed packaging materials
are stiffer than average packaging,
transparent and provide a barrier against
external flavours or odours, keeping the
food products inside fresh. This feature
keeps the package from smelling like the
food product inside it. This packaging
has anti-fogging characteristics and
resistance to grease & oil.”
Thin- and heavy-gauge thermoformingThin-gauge thermoforming is the
process that uses continuous forming of
roll-fed thermoplastic sheet through an
oven tunnel into a forming station, from
trimming to picking and packaging. This
is a more automated process than heavy
gauge. Thin-gauge is used extensively in
the packaging industry.
The heavy-gauge division of
thermoforming feeds cut thermoplastic
sheets into a machine that carries the sheets
through one or more heating stations to
the forming station for moulding and
then out of the machine. Here, secondary
steps are necessary to trim the finished
part. Trimming includes sawing, routing,
shearing and drilling. “In the early days
The Indian thermoforming industry is embracing new technologies and energy-efficient heating options for the machinery, with more and more organisations becoming aware of the need for energy efficiency. Anwesh Koley highlights some of the techniques that are helping this sector to increase efficiency.

of heavy-gauge thermoforming, an acrylic
thermoplastic sheet was hung in an oven
to absorb heat. The material was then
stretched over a mould. After allowing
it to cool, it was removed and trimmed.
Drape forming is still used for various
applications in the manufacturing of
many products,” says Vikram.
Vacuum thermoformingThis process utilises heat and suction to
shape the plastic sheet onto the desired
mould. A secondary operation is required
for trimming features such as cutouts and
holes. This technique is best used for large,
light-weight parts or textured or coloured
parts that do not require finishing. It is
easy to create a mould, allowing for quick
turnaround time, and is well suited for
prototyping and short- to medium-run
production of thick-gauge parts. Vacuum
thermoforming provides the solution for
simplification and aesthetics enhancement
for products such as panel covers, trays,
dividers, guards, pans and display cases.
Applications to improve accuracyHeavy-gauge thermoforming is serving all
industries today. New applications include
building and construction products,
products for the electronics industry,
usually replacing injection moulded parts,
and products for the heavy trucking
industry and automotive manufacturing.
In automotive, the matched moulding
system is commonly used for forming
doors, headlining panels, wheel well
openings and closeout panels in the boot.
A variation of drape forming and match
moulding (slip forming) utilises a mould
with a matching plug assist where the
material is free to slip into the mould
configuration. Slip forming is commonly
used in automotive manufacturing for
forming carpeting. “Another important
industry served by heavy-gauge
thermoforming is sanitaryware, which
includes bathtubs, shower tubs and stalls
and wash basins. The materials generally
used are Acrylonitrile Butadiene Styrene
(ABS), vinyl, acrylic and/or acrylic over
an ABS substrate. Some manufacturers
use cell cast acrylic, heating the sheets in
the convection oven and using vacuum to
form the part,” adds Vikram.
Other methods use ABS with
a co-extruded top coat of acrylic.
This is usually formed on standard
thermoforming equipment. The surfaces
are then reinforced with fibreglass (woven
or chopped fibres) or sprayed urethane
foam. A new, recently introduced process
uses thermoformed finished surfaces
with a waffled thermoformed material
back panel, reinforced with cast urethane
foam between the two parts. The
appliance industry uses vacuum forming
to produce interior boxes and door liners
in refrigerators. The common materials
used here are polystyrene and ABS.
The trimmings of refrigerator parts are
moving from massive punch die to five-
axis robotic router trimming.
The industrial pallet industry is
moving rapidly from wood boxes and
pallets to twin-sheet thermoformed
products. The materials used are generally
high-density and high-molecular-weight
polyethylene. The automotive and food
industries have been driving this change
because of the increasing demand for
recyclable containers and pallets. This
represents an excellent opportunity for
plastics and thermoforming.
Thermoforming technology can also be
used if long packaging lines arise as a result
of the output level and many functions.
The principle of the jumbo tray comes into
play here, as a complete array with trays is
formed first. After being formed, this array
is separated into individual trays with a cut
across the film running direction and placed
on a transmodule, which can then move
through the line according to the tasks
to be carried out. “If several transmodules
are lined up for coupled mode, patented
continuous counter-running can be utilised
for picker line operation. Here, products
move through the packaging line from one
side and the packaging materials from the
other side,” says Vikram.
Areas of growthThe highest material growth in
thermoforming sheet is in high-density
and high-molecular-weight polyethylene.
These materials have high impact,
heat, chemical and weather resistance.
Polypropylene is also beginning to
appear in heavy-gauge thermoforming.
In addition, higher temperature, higher
performance engineering materials such
as ABS and polycarbonate are used where
standard polyethylene or polypropylene
do not have sufficient properties.
The heavy-gauge thermoforming
technique has also grown and increased
production & efficiency. It offers better
quality sheet. Precision controls of
the heat and forming cycles at regular
timings ensure better production quality
and final products. “The acceptance of
well-designed, quality built temperature-
controlled forming moulds, which allow
tighter control of part dimensions,
residual internal stress and the ability to
make repeatable parts, have made heavy-
gauge the preferred technique for a
range of thermoforming requirements,”
concludes Vikram.

What are the current innovations in the thermoforming industry?The Indian market is currently
witnessing enormous progress, with the
packaging sector moving from basic
formats to more advanced technology.
Today’s customer likes to have the
popular formats of the developed world,
eg, Modified Atmosphere Packaging
(MAP) packaging, vacuum packaging,
etc. Such special packaging formats
have a direct correlation to the
product shelf-life and aesthetic look
of the final pack.
Niche packaging plays a special
role in the retail space and is allowing
packaging manufacturers to compete
with global competitors in terms of best
quality and value-added solutions. Roll-
stock thermoform–fill–seal technology
is one of the most mature packaging
formats widely used in the West
to achieve enhanced shelf-life; this
technology ensures packaged product
integrity and is also combined with
high aesthetics. Generally, the machine
uses two continuous rolls of film, which
would be the lower thermoformable film
and the upper lidding film. The benefits
of this technology are enormous, not
only in terms of enhanced product shelf-
life, but also product integrity, high
convenience factor, high aesthetic quality.
These features ensure that convertors
stay at the top of the market and
have satisfied customers at the end of the
supply chain.
How different is Indian packaging machinery market from other markets across the world?With the type of growth curves that India
is riding on in the food processing sector,
a good demand for high-quality packaging
machines is imminent, which can add
greater value to the packaged product.
In the last decade, we saw the Indian
markets graduating from basic packaging
machinery requirements to value-added
niche packaging. Today, India is attracting
all major global packaging companies
who are now willing to understand the
intricacies of the products and processes.
Moreover, the Indian market is
currently booming, and such a market
requires the use of simpler machines and
applications. One must be prepared to
provide the right solution to customers.
This market is quite different from others
and requires an enormous understanding
of the market dynamics. One needs to
learn the products, processes and its value
addition to the food processor. Veripack
will be looking at the larger picture to
collaborate with the Indian manufacturer
in the long run.
What kinds of challenges are you facing in India?The Indian market is huge, and we are
facing numerous challenges. There are
distinctly different markets within
one big India; further, the market is
extremely price-sensitive, and foreign
technology today is still looked at with
suspicion.
We are gearing up to overcome
these challenges, but we would like be
as close as possible to the markets and
customers. We are trying to understand
them, hear them and also learn with
them. Hence, Veripack must make
efforts to overcome the prevailing
challenges in the Indian market in
order to compete successfully in the
long run.
What Research and Development (R&D) activities are you currently involved in?Our R&D is the key to our success,
and currently, we are carrying out our
R&D activities at our factory. We have
been manufacturing these machines for
more than 50 years, as a result of which
our machine technology has evolved
and matured over the years. Today, we
have worked out numerous advantages
of our machines, making them simple
to operate, ensuring robust and trouble-
free operations. All these provisions have
evolved over the years through good
investments in R&D.

How do you see the performance of thermoforming industry in India?The thermoforming industry in India
is witnessing a steady growth as a
result of an increase in application from
the packaging industry. Packaging is
by far the most known application of
thermoforming. This versatile process has
helped modernise several industries such
as automotive, medical, non-conventional
energy sectors and a long list of others.
Thermoformed parts have become
important in two main areas – structural
and functional parts and low-cost, high-
performance packaging applications. The
advantages of thermoforming are the
significantly lower tooling costs and lead
times, as compared to injection moulding
or other closed-cavity methods.
How do you see the progress of this technology in India?The thermoforming industry has
developed despite two fundamental
shortcomings. Many other thermoforming
processes use a resin base in powder or
pellet form. Vacuum forming begins
further down the line with an extruded
plastic sheet, which incurs an additional
process, and therefore, an extra cost to
reach this stage. Generally, a part of the
material is cut away from the formed part,
which, unless reground and recycled, has to
be considered as scrap and accounted for
in expenditure. However, these problems
have been invariably resolved by strict
control of sheet quality and intelligent
mould design to minimise wastage.
What are the advantages of thermoforming over other plastics processing techniques?Thermoforming offers several processing
advantages over other techniques such as
blow moulding, rotational and injection
moulding. The technique requires fairly
low forming pressures, thus enabling the
use of comparatively low-cost tooling
and economical fabrication of relatively
large-sized mouldings, which would be
otherwise cost prohibitive with other
processes. Since the moulds witness
relatively low forces, these can be made
from relatively inexpensive materials and
mould fabrication time kept reasonably
short. This results in comparatively
short lead times. It provides the perfect
solution for prototype and low-quantity
requirements of large parts as well as
medium-size runs utilising multiple
moulds.
What are the challenges facing the sector?Chinese manufacturers are the biggest
threat to us. We follow a single quality
standard, while they have different
product ranges for different consumers.
The customer willing to pay a high
sticker price can opt for a high-quality
product, while the one looking for
quantity and bulk purchase also has his
options, so Indian manufacturers have
little to offer. International customers
prefer Indian machinery, as these are of
better quality, and there is scepticism
regarding the quality of Chinese
products. They produce in bulk, while we
offer quality, and most of our customers
prefer quality. The Chinese lag behind
the Indian manufacturers in terms of
reliability. Domestic consumers do not
even prefer to buy machinery that has
Chinese parts, let alone buying Chinese
machines. Thus, we do not even use
Chinese parts for our machinery.
What are the current key requirements for this sector in India?With cost reduction and competition,
the quality of thermoformed products
is feared to go down. The thickness for
thermoformed products should be set
and made mandatory or else, quality gets
compromised. While growth is expected
in the flexible packaging industry,
consumers are preferring rigid containers,
whose quality can be ensured only by
prescribing a minimum thickness for the
product. Another important factor is the
confidence of investors in the sector. With
rapid implementation of stringent norms
by the Government, new entrepreneurs
are often afraid to venture in this industry
thinking that they might soon have to
look for alternative business avenues.
The fear of ban has been rampant for
quite some time, and this hinders fresh
investment in this sector.

“Thermoforming offers a fast way to manufacture light-weight products”
SPECIAL FOCUS: Roundtable
56 Modern Plastics & Polymers | July 2012
Dipak Vyas Director, Neo Pack Enterprises
The thermoforming industry in India is witnessing an upward-moving graph. The demand for light, recyclable, yet rigid, products is on the rise and thermoformed articles enjoy a market that is benefiting from the above characteristics. The plastics and polymer industry has a wide range of applications in the daily life of people, as it has been substituting most items for over a decade, particularly thermoformed catering items such as food trays, packages, cups, glasses, other beverage containers, bakery and sweets packaging, besides other large industry applications.
Thermoforming yields a part with the same aesthetic properties as an injection-moulded part, but at a fraction of the tooling expense involved in injection moulding. In India, there is a constant need to have light-weight packaging, as it offers rigidity and is cost-effective. This renders thermoforming as a better technique. Considering the current requirements of the Indian packaging market, thermoformed products currently made are fit for the international market.
Although thermoforming companies have been successful in catering to the varied requirements of packaging in India, it remains to be seen how well placed domestic companies are to meet the current demands of a market highly influenced by international trends. Anwesh Koley gauges the opinions of some industry experts on the preparedness of the market to compete on a global level.
Ratnesh Kumar Manager, Dr Froeb (I) Pvt Ltd
While the thermoforming industry is growing due to the varied applications it enjoys, new methods have enhanced the quality of finished products. This is due to the increased use of engineering plastics. Earlier, only polypropylene and polystyrene were used, but now polyvinyl chloride is also being used. With the availability of raw materials in the market and increase in competition, manufacturers are forced to offer better quality at affordable prices. Although competition has often hampered our bottom line, it enables us to understand the customer better and makes us aware of the trends in the global market.
However, in te rna t iona l competition in terms of technology is yet to make heavy inroads into the Indian market. As most of the sector is unorganised, our markets are limited primarily to the local demand. This is also because thermoforming technology is still an unexplored area, though it has a lot of scope. With the advent of global competition in India, we can expect domestic players to gear up in terms of quality, which will enhance the scope for the process.
Govind Bhandari Director, Shrink Packaging Systems Pvt Ltd
Although demand for thermoforming machinery is high, competition is increasing both at the domestic and international level. The biggest threat currently is from Chinese manufacturers. We follow a single quality standard, while they have different product ranges for different consumers. The customer willing to pay a higher price can opt for a high-quality product, while the one looking for quantity and bulk purchase also has his options; thus, Indian manufacturers have little to offer. Although international customers prefer Indian machinery, which are of better quality, they are sceptical about the quality of Chinese products.
It remains to be seen how far domestic technology can match up to international standards and the changing customer requirements. While the thermoforming sector faces several challenges, customer demand and global trends have a long way to go in determining the future of this industry. At present, we require more support from the government to be better prepared to face competition from international companies.
The domestic setup for thermoforming is suited for current requirements. However, since packaging is a dynamic market, customers’ tastes keep changing frequently. Hence, thermoformers must adapt quickly to international requirements to retain their marketshare.
Editorial take:
Is the Indian thermoforming industry ready to compete on a global scale?
Email: [email protected]
58 Modern Plastics & Polymers | July 2012
The Indian plastics processing
industry is witnessing growth
in all verticals. This growth,
coupled with the demand
for light, recyclable yet rigid packaging
solutions, has provided a boost to the
thermoforming machinery segment.
With the rise in their demand from the
packaging industry and recent revolutions
in organised retail, the thermoforming
machinery industry is booming, both
in India and globally. This trend has
led to establishing many manufacturing
companies in the segment, one of the
leaders being Wonderpack, which is a
division of Rajoo Engineers Ltd.
Chandrakant Doshi, Chairman,
Rajoo Engineers Ltd, notes, “The
thermoforming machinery market is
constantly growing in India. Currently,
this technology is used to make cups for
tea and water, but it can also be used
in other segments to make a variety of
products. The key demand driver for the
growth of such machinery is the booming
packaging sector, which consumes almost
50-60 per cent of machines. This demand
will increase in future and be the key
contributor to our growth. Organised
retail will provide a fillip to this industry.”
A humble beginningWonderpack commenced business as
Wonderpack Industries in 1985 at Igatpuri, a
small village in Maharashtra, to manufacture
forming machines. The company grew over
the years and, later, merged with Rajoo
Engineers Ltd in 2010, who were already
present in this segment as one of the key
players; the production facility then shifted
to Rajoo’s premises at Rajkot. Since then,
Rajoo and Wonderpack continue to provide
solutions to the industry, all from a single,
focussed source.
Today, Rajoo caters mainly to
the needs of the packaging industry,
including blister, fast food and cosmetic
packaging. These machines are also used
to make thin- and thick-walled plastic
containers. Khushboo Doshi, Executive
Director, Rajoo Engineers Ltd, says, “The
same technology is also used to make
automotive parts, suitcases & briefcases,
bathtubs, refrigerator liners, door panels,
industrial trays/covers, etc. Thermoformers
manufactured by the company are also
used to make disposable containers, which
constitute a major segment today.”
Product portfolioFrom Rajoo’s portfolio, Dispocon series
thermoformers are sold under the brand
names of Rajoo and Wonderpack. These
machines are developed specifically to
meet highly competitive market demands
for reducing energy consumption, greater
ease of operation, lower maintenance

The state-of-the-art tooling zone
ensures consistently high accuracy levels
in all critical components, and the paint
shop with powder coating facilities has
its own advantages. The huge and well-
equipped assembly shops are partitioned
to accommodate machines of different
dimensions. Highly professional and
skilled craftsmen assemble the lines. The
machines are tested thoroughly as per
Rajoo’s quality standards and customers’
specifications before dispatch. The testing
bay can house over 10 multilayer lines
at a time. The latest entrants to the
Rajoo portfolio are non-woven extrusion
machines, drip irrigation and polyvinyl
chloride/high-density polyethylene pipe
extrusion lines.
R&D initiativesThe company believes in basic and
continuous Research & Development
(R&D). Khushboo Doshi notes, “This
industry always functions on R&D. We also
have our sister concern nearby where we
set up new products, conduct commercial
production, test the technology, designs,
products and then launch these in the
market. These also operate as demo centres
and training grounds for prospective &
existing customers.”
Quality and performance The company is ISO 9001:2008 certified
and the machines conform to CE standards
with regard to safety & operations.
The company’s manufacturing model
comprises a judicious and efficient mix of
outsourcing and in-house manufacturing.
To ensure that the products consistently
live up to and surpass the performance
standards, Rajoo uses the most advanced
machine tools and techniques available
worldwide for stage-wise inspection
of the components & assemblies. Also,
the engineering and manufacturing
departments are integrated through a
digital network to ensure consistency,
reliability and collaboration.
The company’s quality policy is
based on ‘total quality managem0ent’
and world-class manufacturing practices.
Khushboo Doshi notes, “We have
laboratory equipment for testing all
parts of the machines. The machine is
dispatched to the customers only after
completing wet trial and testing. We are in
the process of adopting quality standards
and manufacturing practices employed by
our technical collaborator in Germany
– Hosokawa Alpine – a world leader in
blown film systems. For this purpose,
we send our engineers to Germany for
training and have seen excellent quality
improvements.”
Future growthThe company is way ahead of its competitors
in several aspects. Chandrakant Doshi
avers, “We spend time to understand the
requirements of the customer, and then
provide them with best-quality solutions.
All machines are energy-efficient and of
high quality. We are the forerunners in
providing integrated automated solution
to our customers. We want to continue
growing this way in future as well.” He
concludes, “We are also looking for partners
for technical collaboration or joint venture,
thereby taking thermoforming technology
to the next level.” Photo: Nikhil Patel

Plastics in Electronic/Electrical Applications
INSIGHT & OUTLOOK

INSIGHT & OUTLOOK: E lectr ical grade plast ics
The low cost of
production, energy-
effic iency and
ability to continually
harness plastic waste, while
offering better malleability and
flexibility than metals, have made
plastics the preferred material
for almost all electrical grade
appliances. The light weight and
high-strength characteristics of
plastics are some of the factors
that affect ease of use, logistics
and performance. These have
been possible due to the polymer
compounding process, which has
expanded the scope of plastics
applications.
Plastics in electronicsThe last decade has seen a
phenomenal growth in the
use of engineering plastics.
Especially, additives that impart
thermal conductivity to plastic
compounds electrically or while
offering antistatic properties are
much sought after. The wider
acceptance of such compounds
in replacing metal (particularly
aluminium) and non-conductive
plastics is evident in their
double-digit annual growth rates
over the last decade. One reason
is the decline in their prices
with increasing applications
in electronics, computers,
medical devices, automotive,
aerospace and appliances. This is
remarkable since plastics by itself
does not offer heat resistance,
durability or high tensile
strength. Additives modify
the properties of plastic resins
during polymer compounding,
making plastics a panacea for
engineering applications.
An example of the
achievements with plastics
and additive blends is the
compounded grade of
Polyphenylene Oxide (PPO)
used in the manufacture of
chassis. A plastic chassis part
for a copier device must meet
multiple service requirements
to be effective. The part must
be rigid and flat while the
paper or plastic tape moves
across the surface. It should
have long-term stability, as any
change in dimension affects
the repeatability and accuracy
of copies. Any medium moving
across a good insulator will
build up static electricity on the
insulator’s surface, which can curl
paper and short out the sensitive
electronic circuit boards. The
plastic chassis, which is a good
insulator, must provide a means
for removing the build-up of
The advent of engineering plastics has brought about a paradigm shift in the possibilities of plastics applications. Lionel Alva assesses the role of performance additives in resins that have facilitated the use of electrical grade plastics as well as their future avenues.

static electricity on its surface. The surface
of the part must have dry lubricating
qualities to enable the paper or plastic
tape slide easily across the surface. These
can be achieved with PPO plastic material
compounded with additives.
Thermal properties modification Electrically conductive plastics have
made significant inroads in Electrostatic
Dissipation (ESD) for electronics
packaging and automotive fuel systems
and are growing in both metal replacement
and safety applications, eg, Explosive
Atmosphere (ATEX) environments.
The range of application has broadened
to include silicon-wafer storage boxes,
thermoformed trays for electronic
components, storage and transport
containers, air-cleaner parts, conveyors
as well as protective films, foils & bags.
Unlike conventional migrating antistats
used in packaging, ESD applications
require longer-term protection and/or
lower resistivity. These are better served
by ‘permanent’ antistats such as carbon
black, carbon and metal fibres and
nanomaterials. These additives must show
rapid charge dissipation and cleanroom
compatibility & and low outgassing.
Carbon black compounds and
concentrates offer a good price-
performance ratio and account for a
major portion of conductive plastics.
But, although carbon black is effective in
adding electrical conductivity, its adverse
effects on mechanical properties is a
drawback.
One of the fastest growing areas for
conductive plastics is metal replacement
for weight reduction. Among the most
widely used heat-conductive additives
are graphite fibres and ceramics such
as aluminium nitride and boron nitride.
“Computer, automotive, appliance
and aerospace markets are welcoming
thermally conductive plastic compounds
for transferring heat away from sensitive
electronic components. These are
increasingly specified for heat exchangers,
heat sinks, heat pipes, electronic
interfaces, housings and transformers.
The emergence of energy-efficient light-
emitting diode lighting is also fast turning
into a major growth area. Most specialty
compounders have added some thermally
conductive materials to their portfolios,
aimed primarily at metal replacement.
These offer lighter weight and good
chemical resistance, making them an
excellent alternative to metal heat
exchangers that are susceptible to failure
due to corrosion,” avers Aditya Tandon,
Director, Classic Polymers.
Possibilities and limitations Thermally conductive compounds are
generally not considered to be direct
replacements for metals, but open up a
range of new opportunities for ‘thermal
management’ applications. Parts moulded
from this new generation of materials
can replace metals and ceramics in some
applications, while non-conductive plastics
in others. Uses include custom-moulded
heat sinks on circuit boards, as well as
tubing for heat exchangers in appliances,
lighting, telecommunication devices and
industrial equipment used in corrosive
environments. Heat sinks often involve
plastics overmoulded on a metal heat
pipe. Lighting applications also include
reflectors, laser-diode encapsulation and
fluorescent ballasts.
In temperature sensors such as
thermistors, thermally conductive plastic
encapsulation improves the response of the
temperature sensor. Thermally conductive
compounds are also used to encapsulate
small motors and motor bobbins. The
heat-transfer requirements of ever-
smaller and more power-consuming
electronics have opened the door for
this new generation of cooling materials.
While unfilled thermoplastics have a
thermal conductivity of about 0.2 Watt/
meter-Kelvin (W/mK), most thermally
conductive plastic compounds typically
have 10-50 times higher conductivity, ie,
1-10 W/mK.
Electrifying prospects Ensuring that electronics, lighting and
car engines remain cool are some of
the new roles for thermoplastics that
have been formulated to replace metal
or ceramic. Packing more powerful
microelectronics into ever smaller spaces
would not be possible without heat
sinks and heat spreaders moulded from
new thermally conductive thermoplastic
compounds. In the Indian context, this
provides a tremendous opportunity
for Indian plastics processors to
tap a lucrative market with enormous
business potential.

INSIGHT & OUTLOOK: Micromoulding solut ions
Micromoulding technique
is used to make extremely
small-sized parts of
electronic products.
These parts are measured in micron.
Micromoulding has opened the door to
manufacturing tiny parts relatively easily
at a lower cost and higher speed, and
has thus increased profitability through
material conservation as less resin is
used to create more parts. Amit Mahant,
Director, PK Plastic International Pvt Ltd,
notes, “Micromoulding is a specialised,
precision injection moulding technique
specifically for moulding micro-miniature
electronic components.”
Micromoulding is designed specifically
for producing the smallest components,
typically, with component weights less
than 0.25 gm and even smaller. It has
many advantages, eg, greater accuracy
in finished parts. Its major application
includes plug connectors. Since the
process is designed for smaller parts, few
mould cavities are used in micromoulding.
Thus, the accuracy and reliability exceed
those of conventional moulding. New and
unconventional part geometries are also
possible using micromoulding. Material
choices for micromoulded components
range from commodity olefins and
polypropylene to exotic, high-heat
materials. Generally, in micromoulding,
part weight is 0.001 gm or lesser and part
size is 0.075-inch of diameter or smaller.
Machining parametersIn moulding of electronic components,
micromoulding can offer a range of cost-
effective alternatives for components that
are small, complex and require high-
precision tolerances. Mahant notes, “The
one big reason for companies using this
technology is the cost savings it incurs.
That is because the time taken to mould
a component is a fraction of the time
taken to machine a component. Another
reason is that designers generally do not
want to have the possibility of entry
of foreign matter into their electronic
devices. Micromoulding eliminates
the potential failure mode of having
particulates left after machining. It also
gives more freedom to designers to
introduce intricate features in products,
thereby enhancing their ability to create
more innovative products.”
He adds, “As the trend for smaller
components becomes greater in the
Electrical & Electronic (E&E) industry,
micromoulding can make it easier to
machine complex geometries. In addition,
this technology offers solutions to some
common manufacturing issues specifically
pertaining to the electronic device field,
which has embraced micromoulding as
a key enabling technology for making
micro-electronic components.”
Basket of offerings Micromoulding solution offers numerous
benefits in the moulding of electronic
components. “It can be an excellent
low-cost alternative to machining.
Further, small parts require high-speed
automation to maintain part consistency,
complex, tight tolerance and flash-free
moulding, which can be only achieved
by micromoulding process. In a nutshell,
micro-injection moulding is a lower
cost solution, leads to dimensionally
stable production process and causes no
particle contamination; further, complex
geometries can be achieved through this
process. It uses alternative resins or fillers
to improve mechanical and/or electrical
properties, leading to better surface finish,”
notes Mahant. Some other benefits
include reduced tool sizes, increased part
accuracy, improved cycle times, reduced
part cost and defined colours.
Moulding successControl of the mould design and build
process is essential to the success of
any micromoulding project. Four key
factors contribute to the success of any
micromoulding project, ie, mould tool
design & fabrication, micromoulding
equipment used, the quality of inspection
equipment used and the business
With electronic products becoming smaller and portable, the plastic components inside them are constantly expanding in performance but shrinking in size. Avani Jain analyses the micromoulding technique used for moulding tiny electronic plastic components at higher speeds and lower costs.
MINIATURISINGprecisionwith
Micromoulding solut ions
strategy. Mahant asserts, “These variables
are critical for obtaining a specific
micromoulded component, yet individuals
sourcing micromoulded components
commonly overlook one or more of them.
Attempts to micromould components
using conventional moulding equipment
often fail due to various reasons.
Therefore, a buyer must have adequate
understanding of the mould tooling and
the capabilities of the equipment being
utilised, to be able to make an informed
decision on whether the micromoulder
can provide a successful product.”
Conventional injection moulding
machine has a high shot size relative to the
barrel capacity. Mahant notes, “If plastic
resin is left in the screw for an extended
period, it will affect the mechanical
properties of the plastic resin. The
conventional machine screw, depending
on size, can carry several hundred shots
of material in the injection barrel. This is
important since many conversions use high-
performance plastics in their applications.
These high-performance plastic resins
have a high degree of thermal degradation.
One way in which moulders try to alleviate
this problem is by increasing the number
of cavities in the mould to increase the
shot size. This resolves the issue with the
shot weight. The machine specifically
designed for micromoulding process
addresses the issues of melt cushion size,
speed and pressure.”
He elaborates, “The last factor to
consider, and one that is often overlooked,
is the quality inspection equipment.
Buyers must verify whether the
suppliers have the capability
to measure micromoulded
components. For visual
inspection, a microscope
(0–50X) is needed. For first-
piece inspection, optical
measurement inspection
systems are suitable
(0–200X), which can handle
most of the work. For in-process
inspection, the micromoulder should
have a camera inspection system
incorporated in the injection moulding
equipment. In combination with a robot,
the equipment continuously provides
100 per cent visual inspection. This ensures
that the moulded component has been
inspected and separated correctly from
rejects. Otherwise, an operator would have
to perform a manual in-process inspection.”
Future trendsAt present, micromoulding machines have
plunger injection, programmable controls,
built-in gate cutters and needle valves.
Mahant avers, “In future, these machines
will see new developments in the form
of small screws (14-16 mm), high-speed
injection up to 700-750 mm/sec, low
injection volume and shot size of 1.0 gm
or smaller and development of two-stage
machines, ie, screw or plunger type.”
He further adds, “The use of all-
electric micromoulding machines for
moulding electronic components offers
various benefits along with precision and
accuracy. These can lead to energy savings
up to 80 per cent, helping to achieve
accuracy and repeatability. In future, the
machines will make use of tie bar-less
mould-clamping structure, which will
result in much larger mould space and can
be equivalent to wide platen style. The
machine will come with direct lock-ball
screw with cross head to ensure accuracy
and stable clamping and lead to equalised
force on the mould. The machines will
also incorporate mechanical ejector with
servo control for enhancing machine
efficiency.”
A positive outlookThe increasing complexity of contemporary
electronic appliances has resulted in
more components per appliance. This
has increased the pressure on injection
moulders to constantly upgrade machines
to meet specialised requirements. The
added features demand more part strength
and miniaturisation, which has increased
the demand for micromoulding solutions.
Due to various benefits offered by
micromoulding solutions, their demand in
moulding electronic compounds and in the
E&E industry will continue to increase in
the future.

INSIGHT & OUTLOOK: Inter face - Dr Har indu Vyas
How is the demand for engineering plastics in E&E sector?Plastics in E&E applications cover
the third largest plastics market in the
world. Without plastics, some of the
electronic or electrical applications
would not be practically possible or be
very expensive. In E&E applications,
the contribution of thermoplastics is
75 per cent; thermoset, 15 per cent;
polymer composite, 9 per cent; and
others 1 per cent.
Insulation is the most important
property required by the material
used in the E&E sector. The
materials conventionally used for
these applications are wood, ceramic
composites, polymer composites and
engineering plastics. Wood and ceramic
composites have some drawbacks in
comparison to engineering plastics, eg,
high weight, brittle nature and high
moisture absorption. To overcome these
drawbacks, presently, manufacturers are
using engineering plastics in the E&E
industry. Thus, the demand for these
plastics has increased. Also, engineering
plastics are easily processable in injection
moulding machines, with excellent
flame resistance and dimensional
stability. These have excellent electrical
properties, eg, dielectric strength,
insulation resistance, arc resistance,
comparative tracking index, and
properties for glow wire test & ball
pressure test, etc. Thus, the demand
of engineering plastics is continuously
increasing in the E&E sector.
What are the major usages of engineering plastics in E&E sector? Engineering plastics have wide
applications in the E&E sector. These
are used in electronic applications,
eg, CEE connectors, single-socket
outlet, plug socket set, connection
unit, Printed Circuit Board (PCB),
electrical accessories, etc. Presently,
engineering plastics are well accepted
in optical cable application and its
parts, microwave parts, switchgear
application, telecommunication, low
voltage application, etc. Electronic
instruments used in medical diagnosis
are unimaginable without using
engineering plastics. Thus, the
application of engineering plastics in
the electronics sector is fast increasing.
What are the recent trends in the sector? The use of engineering plastics in
the electronics sector includes PCB,
switchgear applications, high-dielectric
application, excellent arcing resistance,
etc. Light-Emitting Diode (LED),
which utilises engineering plastics, is one
of the excellent innovations used across
the world. Engineering plastics are
also used in solar panels. Thus, almost
90 per cent of the E&E sector uses
engineering plastics.
What are the leading innovations in the sector? Research is underway to find new
applications of engineering plastics in
the E&E sector. Some of the leading
innovations in this sector include nano-
filler engineering plastic compounds
to replace ceramics or thermoplastics
in E&E applications, flame-retardant
engineering plastics, high-dielectric
strength polymer blends, etc. In
Europe, Restriction of Hazardous
Substances (RoHS) in electrical and
electronic equipment and Waste
Electrical and Electronic Equipment
(WEEE) directives mandate that flame
resistance be achieved without the use
of halogenated components, one of the
favoured areas of research.
What are the future trends in engineering plastics in the E&E sector? Nano-plastic composite, clay composite,
carbon fibre composite are the future
of E&E sector. The demand for
these materials will increase in the
E&E sector, due to their numerous
advantages. Depending on the
electronics application, plastics is
chosen for its rigidity or flexibility,
toughness/durability, resistance to low
or high voltage and electrical insulation
or conductive properties. Ease of
fabrication into complex shapes is
also a requirement. Thus, in terms
of usage of engineering plastics
in the E&E sector, polycarbonate,
acrylonitrile-butadiene-styrene, Nylon,
thermoplastic polyester, polyphenylene
oxide, fluoropolymers, polyacetal,
polysulphones, etc, will be the future of
this industry.

INSIGHT & OUTLOOK: Polyamide al loy

Mandar Amrute
Polyamides are known for
their outstanding mechanical
properties, tensile strength
and abrasion properties. One
of the most common problems with the
polyamide family is its property of water
absorption. Polyolefins, on the other hand,
have good hydrolysis properties with the
ease of processing on standard plastic melt
processing machines. In general, polyamides
are observed to be incompatible with
polyolefins. Therefore, polyamide alloy is
a Polyamide (PA) 6- or PA66-based alloy
with polyolefin, which offers the benefits of
combined properties from polyamides and
polyolefins. Orgalloy® – a type of polyamide
alloy – is based on a patented technology,
which ensures homogeneous mixing and
ease of processing, combining the benefits
of both polyolefins and polyamides. This
technology also ensures consistency in the
product, thus resulting in improved and
consistent performance of the final product.
Low moisture uptake resulting in
retention of mechanical and
electrical properties
Excellent dimensional stability
Easy to process on standard
processing machines
Good chemical resistance
Low density
Good recyclability [Polypropylene
(PP), Polyethylene (PE), PA, etc)]
Light in weight as compared to
PA6 and PA6/6; it is clearly visible
to difference in density of these
materials resulting in low-weight final
component
Excellent barrier properties against
polar and non-polar gases and solvents
Multilayer film packaging A layered structure is usually used in
multilayer film packaging for food items.
Polyamide has been the material of
choice for the barrier layer since long. In
multilayer packaging, PA is often used
when an enhanced barrier function is
required, due to its unique combination
of features:
Mechanical strength
Excellent impact, puncture resistance
and tear resistance
High transparency
Thermal stability
High oxygen barrier
High aroma barrier
Easy thermoformability
As a barrier material, PA does much more
than just preventing oxygen migration
into the package, which helps slows
down spoiling or discolouration of the
packaged material (eg, meat, cheese fruit
juice packages). It also provides a barrier
to aroma molecules, which helps prevent
loss of aroma from the packaged material,
as well as delays contamination of the
package's environment by the aroma
material. Some examples of packages
where aroma conservation is necessary are
spices, fruit juice, detergents, toothpaste,
etc. Also, herbicides, pesticides and
fungicides may require a barrier material,
such as Nylon, to prevent migration of
the active, potentially harmful ingredient
as well as the organic solvent into the
environment during storage. As an
additional feature, a well-designed barrier
material will not absorb flavour or aroma
constituents from the packaged item.
Advantages and applications Polyamides are impermeable to non-polar
An excellent barrier material, polyamide offers features such as reducing oxygen migration into the package, which helps delay spoiling of the packaged material. One such polyamide alloy is Orgalloy®. The properties, processing methods and some of the key applications of Orgalloy® in the packaging sector is outlined here.

solvents and gases (eg, hydrocarbons,
oxygen), but, unlike polyolefins, these have
poor barrier to polar solvents, eg, water
and alcohol. Polyamide alloy combines
the advantages of both polyolefins and
polyamides, with simultaneous barrier
to polar and non-polar solvents
& gases.
Another advantage of
polyamide alloy is the ease
of processing on machines
designed for polyolefins.
Polyamide alloy can be used
to produce three-layer barrier
films without using tie layer
on the same machine designed
for polyolefins, as polyamide
alloy has good bonding with
polyethylene. Polyamide alloy
features good weldability at
production speeds normally
achieved with PE. Thus, the
excellent barrier properties,
mechanical properties, ease of
processing and low sensitivity
to moisture of polyamide alloy
make it suitable for packaging
applications such as cosmetics
packaging, industrial packaging
films, agricultural barrier films
and food packaging films
& containers.
Providing a unique barrier In the field of barrier packaging,
polyamide alloy is a unique
material that can bring about
various changes without
changing anything on one's
standard machine. Apart
from mechanical properties,
low moisture pick-up and
dimensional stability, this alloy
has a lot to offer in packaging
& films where low permeation
properties are required. Ease of
processing on standard extrusion
and injection machines designed
for polyolefins is an added
advantage. Hence, polyamide
alloy can be an ideal material for
any application that demands
barrier properties.

INSIGHT & OUTLOOK: Cost informat ion in project management
72 Modern Plastics & Polymers | July 2012
M Hariharan
V arious methods are used in management of project cost and schedule concerns. One of these is ‘Cost Information
Need’. In cost management, there is only ‘A’ Cost, and no ‘The’ Cost, which depends on the requirement. Cost information requirements for a project may vary according to the stage of a project.
Project cost information needs These include cost estimation at
conception stage, cost budgeting at planning stage, cost analysis and cost tracking during execution stage and compliance requirement.
Compliance takes precedence Similar to manufacturing firms, in project firms also, formal cost analysis is restricted to compliance. Compliance should be properly maintained. But, a common mistake is to use it mindlessly for other requirements. Project companies generally believe that
Enterprise Resource Planning (ERP) can track their costs well. But, although it is satisfactory for compliance and cost control, configuring ERP to meet only compliance requirements undermines its potential.
Cross-disciplinary costing cell In some project companies, cost estimation is an exclusive club of engineers, while cost reporting through execution is the domain of accountants. Here, a Cross Disciplinary Costing
Monitoring and regulating cost needsThe previous two articles (Apr ’12 and June ’12) dealt with project cost control on the basis of the QRST pattern and the S-Curve & 4D Grid. This article focusses on cost information needs of project cost management.
Detailing and grammar of cost numbers, which depend on the stage of a project
Stage of project Detailing required Grammar of information
Project conception stage
Assessing project viability;Participating in tender;Funds requirement planning
Macro-level information based on rough order of magnitude; planning horizon is longer, so detailing is difficult. But, with long experience in such projects, micro-level details can be achieved.
Future cost information. What will be the cost?
Project planning stage
Project cost baseline for cost control Micro-level detailing using parametric modeling or bottom-up estimation is critical. Resource and cost details at Work Breakdown Structure (WBS) level are required for cost budgeting. For short-term projects, this will be same as in the conception stage. But, for long-term projects, such as infrastructure, detailing must be done for a shorter time horizon.
Near future cost information.
Project execution stage
Cash planning for short-term requirement
Projects typically require cash outlay on daily, weekly and monthly bases. This must happen at the site. For this, a detailed cost estimation with time schedule for disbursement is needed. This estimation will be at the level of cost elements, eg, salary, travel, etc.
Near future cost information.
Actual cost tracing for cost control Cost detailing at WBS level is required. Cost classified as direct and indirect, variable & fixed is critical for effective cost control. This requires detailed analysis.
Immediate past cost. What was the cost?
Cost analysis for decision making during execution
During execution, site incharge takes many spot decisions. Project head takes decisions for course correction. Cost analysis is detailed at a micro level. Cost estimate numbers used for tendering, cost estimates used for budget and actual cost numbers captured in the system are of limited use for this. One must look beyond the formal cost information system to cull out the information required for this purpose.
Near future and immediate past cost.
Milestone billing for cost plus projects
Direct costs captured at WBS level plus indirect costs apportioned to the stage (including Administration costs) are relevant.
Past cost information. Cost rates based on the agreement.

for cost estimation for tendering, project viability and funds planning; cost budgeting for project cost baseline; providing inputs for decision-making during execution; cost tracking & deviation reporting for cost control; and inputs for milestone billing.
Resolving cost conflicts Distinct departments like engineering, estimating, project monitoring and costing working in silos are not of much help. Most inter-departmental conflicts in project companies arise from cost conflicts. Thus, understanding the uniqueness of cost information needs for projects is critical for their on-time, at-cost completion.

INSIGHT & OUTLOOK: Product grade transi t ions
74 Modern Plastics & Polymers | July 2012
Sunil Chaudhari
Typically, during a downturn,
most processing companies
tend to shift their priorities
away from maximising
throughput to minimising waste and
reducing energy consumption as a means
to increase return on investment. This
change in focus thus leads to a stronger
emphasis on the safety parameter.
The experience of several polymer
production plants is a case in point. In
these plants, in particular, as also in other
specialty chemicals facilities, processes
are constantly changing, as they run
on a fixed set of operating conditions.
Companies continuously produce
various products with different densities,
viscosities and material properties.
One of the key environmental
challenges that organisations face is that
each grade transition produces many
tonnes of off-specification material. It is
frequently difficult, or even impossible,
to sell these intermediate grade products
at a premium rate. While blending
and recycling techniques are available
in this eventuality, which are more
environment-friendly, these cost energy
and such products thus manufactured will
probably invariably have to be dumped
into landfills. There are associated safety
implications as well. Carrying out a
transition from one product grade to
another is one of the most safety-critical
operations in a chemical plant.
A harmonised approachUntil recently, no commercially available
technologies were available to support
automation and optimisation of product
grade transitions. Minimising the
waste created by the transition from
one grade to another is something that
Advanced Process Control (APC) can
now help with, thanks to the innovative
use of non-linear as opposed to linear
control and advancements in procedural
automation technology.
Nevertheless, it is not only the
development of the process that is
important here, but equally important
is orchestration of the functions of the
controller and having a technology that
can coordinate and provide synchronised
sequencing logic to some of the manual
processes in the plant. For instance,
AspenTech’s clients have witnessed
considerable success in this area. We
have been able to achieve an average of
50 per cent reduction in transition waste
for them, with some clients significantly
exceeding this value.
This is a relatively recent but hugely
significant breakthrough. Handing over
the product grade transition process to
an automated controller has never been
taken lightly by operators who have
historically not been fully convinced
of the safety credentials of automated
processes. Therefore, for many years,
while APC was being widely deployed
across ethylene and refining plants, it
was not extensively used in the polymer
industry. Since the collaboration was
complex between what the automated
controller needed to do and what
operators were required to do, both on
the plant and in the control room, it
was not deemed safe to use the APC
Rising emphasis on productivity and safety in companies, particularly during crisis, has resulted in the need for an approach that could reduce energy consumption and enhance return on investment. Manufacturers, therefore, need to automate their processes and operations to attain these objectives as well as enhance productivity and profitability.
Advantages of an automated approach

technology. For instance, AspenTech has managed to
tackle such problems by using a combination of sequencing
technology and non-linear control.
Over the past few years, the use of this method has become
an expectation with companies in the sector. If a polymer
company requires an advanced process control, then it expects
the solution to optimise its product grade transitions. Polymer
companies have moved on from being concerned only about the
safety of handing over a process to a remote controller towards a
situation where they recognise this as the right approach.
Working in tandemThis paradigm shift has been driven by polymer companies
themselves. In the earliest days of APC, vendors have tried
to push a certain technology as being a solution rather than
listening to their customers’ requirements.
For example, they initially tried to promote the standard
version of APC, though it did not work. Later, they shifted
their focus to consider the viability of neural networks as a
potential solution. Again, the sales pitch was unsuccessful,
primarily because the ability of this technology to deliver
precise predictions about product grade transitions can often
be unreliable.
Ultimately, vendors realised that the best approach was to
work painstakingly with polymer companies in order to develop
safe as well as reliable modelling and controller technology
that closely fitted their business objectives of reducing waste
not just in transitions, but also during in-grade product runs.
Being able to manage this process has further environmental
benefits because the ‘off-spec waste’ created by the latter process
would either have to be reprocessed, with all attendant energy
implications, or scrapped. The key was to gain knowledge and
proofs of concepts and ensure that business needs were driving
the technology development rather than vice versa.
Futuristic solutionsThis meticulous approach has ultimately borne fruit. Polymer
companies today no longer have to be concerned about
environmental and safety issues surrounding product grade
transitions. They can now be confident about the resolution
of the problems. Moreover, manual techniques combined with
high-quality sequencing technology and non-linear controls
have provided them with the solution that they have been
seeking for many years.

AUTOMATION TRENDS: PC-based technology
The advancements in computer
technology and development
of artificial intelligence has
made it possible to greatly
reduce the cost and lead times in the
design & manufacture of injection moulds.
This is due to the optimisation of the
overall manufacturing process. However,
understanding the intricacies of injection
mould design is highly complex. This
is because injection moulding imbibes
several sub-designs related to various
components of the mould, and thus needs
an absolutely keen understanding of the
overall manufacturing process.
Design considerationsMould design affects the productivity,
mould maintenance cost, manufacturability
of mould and quality of the moulded
part. Until now, most of the work in
mould design has been directed towards
application of expert systems, knowledge-
based systems and artificial intelligence to
eliminate or supplement the vast amount
of human expertise required in the
conventional design process. A number of
studies have also been done on improving
the design of specific components of an
injection mould.
The design principles of cavity layout
and patterns of mould design can be
presented easily in a knowledge-based
design system. This helps build an effective
system to address the complexities.
Current practice for injection mould
design, especially cavity layout design,
depends largely on designers’ experiences
and knowledge. Therefore, one can
use knowledge engineering, artificial
intelligence and intelligent design
techniques for generating accurately and
efficiently an acceptable cavity layout
design in an injection mould.
The criteria to select a suitable
layout pattern for design depend on
working environments, conditions and
requirements of customer and are based
on a designer’s skills & experience.
Intelligent design techniques should
be used in systems designed for such
situations, especially for routine or
innovative design. Design of an injection
mould mainly involves considering
the design of the certain elements or
sub-systems such as mould type, number
of cavities, runner system, ejector system,
cooling system, venting and mounting
mechanism.
One cannot realistically expect a
designer to keep close scrutiny on all
design parameters. However, one must
understand that cavity design and
layout are the key factors affecting all
other activities. Application of advanced
knowledge based techniques to assist
the designer in cavity layout and
design enables effective creation and
development of a capable computer-aided
injection mould design & manufacturing
system. “A fully integrated Enterprise
Resource Planning (ERP) system
should be used to enhance quality and
consistency in production. Especially, in
high-volume production, monitoring of

can help develop a highly effective ERP
system,” avers Gaurav Bansal, Director,
Kiran Consultants Pvt Ltd.
Challenges in IndiaA key problem in India is investment,
infrastructure and availability. The
market is largely driven by Small and
Medium Enterprises (SMEs) who do not
possess the economies of scale that larger
manufactures have. Thus, adoption of
new technology becomes a major problem
since it does not justify the return on
investment for manufacturers. However,
with recent technological developments,
an ERP solution can be acquired at a
much lower and affordable cost. This will
greatly enhance the competitiveness of
manufacturers in the Indian scenario.
“In the Indian scenario, many SMEs
view ERP systems as cost-prohibitive.
Also, having an effective ERP system for
the entire manufacturing process would
require an approximate investment of
` 30-40 lakh, which many manufacturers
are not willing to make. Better awareness
is required regarding the advantages of
ERP solutions, and it is important to
consolidate the growth of the plastics
industry in India. We also provide training
to employees since a full-time operator
is needed to monitor manufacturing
activity,” observes Bansal.
Impact on qualityA healthy mix of cutting-edge hardware
and sophisticated software enables the
creation of a highly integrated approach
to injection moulding manufacturing.
Since injection moulding is used for
manufacturing of a wide variety of parts,
the software must adapt easily to new
applications. Further, optimisation of the
material used ensures minimal wastage in
various stages of production.
Computer-assisted technology is
designed to optimise the machinery
parameters, including process stabilisation,
shortened cycle times and production
efficiencies, which are most critical
to zero-defect medical, automotive,
electrical component, optical & liquid
silicone rubber plastics injection moulding
operations. Conventional injection
moulding machinery optimisation
involves time-consuming, manual
trial-and-error adjustments of relevant
parameters until all quality targets are
met. During this phase, user experience
with similar parts, materials and injection
moulding machinery is critical. Online
process optimisation (ie, during active
production) is even more complex, as
each parameter change can mean new
machinery setting modifications, cycle
time data recording and moulded parts
measurements.
“Our injection moulding systems
consist of Programmable Logic
Controllers (PLC), precise machining
tools, temperature regulators and several
highly advanced features that help in
complete automation of the injection
moulding process. While being an
expensive proposition, the use of CAD
has helped enhance the quality of our
volume-driven manufacturing, while
reducing energy costs,” avers Hiren Bhatt,
Proprietor, Sai Shakti Plastotech.
Facilitating industry needsIn the context of an injection moulding
manufacturing facility, ERP may be
used to facilitate on time delivery,
eliminating unnecessary downtime, and
ensure compliance with industry &
government standards. A critical benefit
is the ability to track and trace products
across the supply chain. This is especially
important for medical, safety and military
applications. A product failure in the
field can be isolated according to lot
number and a replacement or repair can
be pushed to all customers affected, thus
allowing the manufacturer to proactively
solve problems before they impact a large
number of customers. Hence, in today’s
fast-paced business environment, an ERP
system is critical for the competitiveness
of industries.

In high-volume production, monitoring of the entire manufacturing process without the aid of technology is an arduous task. A keen understanding of various injection moulding parameters as well as a pre- and post-production analysis can help develop a highly effective ERP system.
Our injection moulding systems consist of Programmable Logic Controllers (PLC), precise machining tools, temperature regulators and several highly advanced features that help in complete automation of the injection moulding process.
Extrusion can be seen as not
only a final forming process,
but also as an intermediate
process for other processing
techniques such as film blowing and
injection & blow moulding. The efficient
operation of extrusion screws used
in the extruder is, therefore, the most
essential aspect of the plastics processing
industry, as these perform various tasks
that enable manufacturers to achieve
the desired results. Screws can be used
for a plethora of applications such as
conveying the polymer, mixing, shearing,
compressing, degassing or heating
the polymer through convection and
many others.
Jaymin Pithwa, Director, Konark
Plastomech Pvt Ltd, notes, “For ensuring
maximum energy efficiency, the machine
designs have changed drastically over the
years. Every company involved in plastics
extrusion is trying to adopt strategies to
produce maximum at a lesser energy
cost. A good extrusion screw design
technology can help achieve the objective
of reducing the energy consumption to a
large extent. Further, with each passing
day, the companies are developing
new technologies that can minimise
mechanical losses.”
The core matter The extrusion process is highly dependent
on electricity, and most of the energy used
is directly related to machine operation.
Various steps can be taken to reduce
energy consumption of the extruder
in plastic extrusion processes. The
heart of the extruder is extruder screw.
This is a long cylinder with a helical
flight wrapped around it. The screw is
important because it mostly determines
the conveying, heating, melting and
mixing of the plastic materials. The
stability of the process and quality of the
extruded product depend on the screw
design. The screw rotates in a cylinder
that fits closely around it.
Extrusion screws perform four
main functions – consistent feeding of
the resin or axial forwarding, uniform
melting of the resin, steady consistent
pumping of the melt and homogeneous
mixing of the melt pool. Constraints
like head pressure, throughput rate and
product quality determine proper screw
design for applications. These points
must be considered while designing the
extrusion screws.
Types of screwsThe field of extrusion screws has
undergone tremendous development
over the past decade. The screw used
in extrusion processes can be classified
in different ways. These can either be
classified based on their methods of
working or the functions they perform.
Screws may also be classified based
on the types of materials for which
these are most suitable. Screws can be
classified as single-stage or multi-stage
(non- vented or vented) screws; simple

An efficient screw design technology helps reduce considerably the energy consumed during the plastics extrusion process. With the industry continuously working on modifying the screw geometry and design, Avani Jain analyses the role and benefits of a good extrusion screw design technology in reducing energy consumption.
Energy savings through best-in-class processing

Extrusion screw design
conveying screws or barrier screws
or mixing screws and screws for low-
viscosity polymers, medium viscosity
polymers & high viscosity polymers.
Some other modes of classifications
could be single-flight or multi-flight
screws; screws for smooth-bore extruders
or grooved-feed extruders; screws for the
primary extruder of foam extrusion lines
and screws for the secondary extruder
of foam extrusion lines (cooling screws).
They may also be classified as melt-fed
screws or plasticising (solid fed) screws.
Barrier-type screw designs are most
widely used in the extrusion industry and
help in achieving energy efficiency. The
advantages derived from well-designed
barrier screws are improved rate, lower
melt temperature and improved melt
quality. Barrier screws, due to their
mechanism of melting, produce higher
internal pressures through the barrier
section helping to increase the melting
of material. In contrast, general-purpose
screws do not produce as high internal
pressures at the end of the transition
section as do barrier screws. Primarily,
barrier screws are designed so as to
increase the throughput in single-
screw extruders and improve the melt
quality. Twin screws also help in process
optimisation. These are well known
for their ability to offer optimisation,
efficiency and flexibility in processing
tasks such as mixing, compounding or
reactions between polymeric materials.
Energy consumptionA high percentage of the total energy
requirement (up to 30 per cent) for
moulding and extrusion equipment
is used to plasticise material. Screw
design is the most important feature
on extrusion machines. Screw design
technology is constantly evolving and
the processors are always involved in
gauging the appropriate screw diameter,
geometry and length-to-diameter ratio
appropriate to a specific material and
plasticising rate.
Energy savings of 20-30 per cent are
claimed in some instances. If the rate
of machine use is high and production
demands are predictable, a screw
replacement may be warranted. Screws
and barrels should be checked every five
to six months. Worn screws must be
replaced or repaired as the payback is
quick (ie, a few weeks).
Fixing the screw designPoor screw design is a common cause
of overheating of plastics and is usually
the reason why barrel cooling is needed.
Operations where multiple extruder
zones are cooled at 100 per cent are
inherently inefficient. Pithwa notes,
“The most energy-efficient extrusion
operations are those where most of the
heat is supplied by the extruder screw,
with only a small amount of heating by
the barrel and die heaters and without
the need for cooling of the extruder.”
The best solution to overheating
caused by poor screw design is to
change the screw geometry. If an
extruder with poor screw design runs at
0.25 kWh/kg and with a good screw
design at 0.20 kWh/kg, the energy savings
will be $ 36,000/year at $ 0.10/kWh and
a throughput of 1,000 kg/hr running
24 hr/day and 300 days/year. Thus, a
well-designed extruder screw can recover
the costs faster. It also offers various
benefits such as lower melt temperatures,
less degradation of the plastics, better
physical properties in the extruded
product, better product appearance and
consistency.
Thus, irrespective of the age of
the machine, it is essential to get the
right extruder for the job and the screw
diameter & design should be checked
to ascertain that they are appropriate
for the polymer product. Pithwa notes,
“One must decide on the screw design
and diameter right at the design stage. A
well-designed extruder screw can cover
up for the high prices relatively quickly,
based only on reduced energy cost.”
The right design With energy management concerns
rising worldwide, the companies in future
will have to adopt various other measures
for decreasing their energy consumption
in plastics extrusion process. For this, the
first step is to get the extruder right. If
the extruder runs at optimum conditions,
the need for downstream cooling and
calibration will be minimised. To achieve
this, deciding on the appropriate screw
design right at the design stage will be
beneficial. Thus, the companies need to
increasingly adopt strategies to ensure a
good screw design technology that helps
minimise energy consumption. The
ideal screws will fulfill the performance
criterion to deliver maximum output for
the available motor power with minimum
frictional heat generation. Ideally, there
should be no need for barrel cooling.
These two criteria ensure that energy
consumption remains at the lowest.
These are only some of the steps for
reducing energy consumption through
extrusion screw design technology. But,
a complete extrusion process has several
other components that consume large
amounts of energy, such as dryer, resin
conveying system, water-cooling and
circulation system. Various steps should be
taken to reduce the energy consumption
of these components as well.

POLICIES & REGULATIONS: P last ic waste management
84 Modern Plastics & Polymers | July 2012
The ability of India to become a major world player in all aspects depends greatly on how well it uses its most
abundant resource – its population. The huge population of the country as well as the economic developments have created numerous issues, one of which is waste disposal – particularly non-biodegradable plastic waste. The emergence of supermarkets and mall culture has brought to the fore increasing utilisation and ubiquitous applications of plastics, right from packaging food stuff and electronics to automobiles & construction. Since any threat to public health must be viewed with urgency, there is a pertinent need to understand effective waste disposal methods to ensure sustainable and healthy growth in India.
Since the Indian industry is still in the initial stages of the retail and consumer revolution, it is possible to bring in a tenable policy and regulatory framework for the management of plastic waste.
The most effective way to do this is to make a concerted effort at all levels, by including the Government, the plastics industry and even the consumers to some extent. Thus, there is a need to build better awareness and promote responsible behaviour on part of plastics manufacturers as well as those concerned with the plastics industry. With the help of an effective strategy, the country would be able to achieve a manufacturing consonance to ensure that the promise that this industry holds does not get affected. It would also lead to an amenable environment
for industrial growth, which is the need of the hour, considering India’s below average performance during this fiscal quarter.
Key challengesPlastic waste forms a significant part of the total Municipal Solid Waste (MSW). It is estimated that approximately 10,000 Tonne Per Day (TPD) of plastic waste is generated in the country, ie, 9 per cent of 1.20 lakh TPD of MSW. The plastic waste constitutes two major category of plastics – thermoplastics and thermoset plastics. Thermoplastics constitutes 80 per cent and thermoset, about 20 per cent of total post-consumer plastic waste generated in India. Thermoplastics are recyclable plastics, eg, Polyethylene Terephthalate (PET), Low-Density Polyethylene (LDPE), Polyvinyl Chloride (PVC), High-Density Polyethylene (HDPE), Polypropylene (PP) and Polystyrene (PS). Thermoset plastics are alkyd, epoxy, ester, melamine formaldehyde, phenolic formaldehyde, silicon, urea formaldehyde, polyurethane and metalised & multilayer plastics. The environmental hazards resulting from the mismanagement of plastic waste include the following aspects:
Littered plastics spoils the beauty of cities and chokes drains, making public places filthy
Burning of garbage containing plastics emits polluting gases and causes respiratory diseases
Garbage mixed with plastics interferes in waste processing facilities and may cause difficulties in landfill operations
Recycling industries operating in non-conforming areas result in unhygienic conditions
A growing population and vibrant economy brings with it the issue of increasing waste. Since plastic waste is considered hazardous to public health, Lionel Alva assesses the importance of having a strong regulatory framework to manage this waste.

“In terms of post-consumer waste, especially with flexible packaging (eg, heavily printed, multilayer/laminated/vacuum metalised pouches), currently, there is no efficient and professional waste disposal system in India. The challenges arise at various levels, since there are no sorting methods available at source, which results in waste disposed at an individual’s convenience,” avers Deepak V Mehta, Partner, Leevams Inc. He adds, “The advent of malls, super stores, mega stores, etc, in every city and town will further increase the use of convenient flexible packaging, while the waste disposal system will further deteriorate. Effective means of waste collection, disposal and recycling is the only resort to respect the growing consumption rates.”
Need for regulations Plastic waste is recycled in India in an unorganised way. Almost 60 per cent of the plastic waste collected and segregated is recycled back into materials for further processing into consumer products, while the remaining is left unutilised. Regulations and legislations are being enforced in two states of India, viz, Haryana and Himachal Pradesh, while a National Plastic Waste Management Council Task Force has been set up by the Ministry of Environment & Forests, Government of India, in association with Department of Petroleum and Chemicals, Ministry of Urban Affairs, Municipal Corporation of Delhi and various groups/associations of plastics manufacturers. There is scope for recycling/management of plastic waste as an organised activity in India. Mehta says, “Plastic Waste (Management and Handling) Rules, 2011, has certainly come into force; however, its understanding and implementation in the true sense will take time considering the diverse spread of the industry and huge population of the nation. The real effect can only be seen after the move is made in the right spirit and perspective.”
At present, no penalties are imposed on plastics manufacturers for improper handling of plastic waste. This move would help improve the image of the plastics industry by making it more environmentally responsible, thus setting
a landmark precedent that would actually improve its prospects in India.
The National Plastic Waste Management Council Task Force has recommended a strategy and action programme for Plastic Waste Management in India. The Ministry of Environment and Forests, Government of India, has issued criteria for labeling plastic products as environment-friendly under its ‘Ecomark’ Scheme, in association with the Bureau of Indian Standards (BIS). One of the requirements for plastic products is that the material used for packaging should be recyclable or biodegradable. The BIS has issued specific criteria for recycling of plastic waste while providing instructions on how waste should be classified and collected; further, there is a will and desire among Government bodies as well as Non-Government Organisations (NGOs) to make the existing guidelines stringent.
However, while formulating Indian standard specifications for various plastic products used for critical applications such as plastic piping system, water-storage tanks and packaging for food articles, a clause is included, which reads – ‘No recycled plastic waste shall be used’. The Ministry of Environment and Forest in association with BIS has carried out an exercise to include the use of recycled plastic waste where appropriate in the manufacture of plastic products, and this should be specified accordingly in the relevant Indian waste disposal guidelines.
Preventing wastagePlastic waste has several facets involving various stages where waste occurs, and it is important to bring about an effective strategy to deal with different types of waste. Recycled polymers are finding new avenues for application. If the waste is not handled in an effective manner, then it could lead to a serious situation. The implications of bringing in better regulations would ensure that plastics manufacturers utilise waste in a proper manner. Alternative strategies such as the use of non-recyclable waste for roads and power generation can also be explored, which could lead to innovative methods for waste management while enhancing the prospects for the industry in the global arena.

Plastic Waste (Management and Handling) Rules, 2011, has certainly come into force; however, its understanding and implementation in the true sense will take time considering the diverse spread of the industry and huge population of the nation.
The Indian plastics processing machinery industry is incessantly setting up new highs
year over year, due to the enhanced ability of Indian machinery suppliers to accommodate innovative technology. Evolved over the years, the plastics processing industry has seen some major innovations recently, which have a long-term impact on the functioning of machines. With overall cost reduction including labour costs and quality improvement as the main driving forces, the plastics processing industry offers a comprehensive choice of technologies and application techniques.
Some of the major trends for increasing the operating efficiency and reducing costs in all sectors of the plastics processing machinery segment such as injection moulding, blow moulding and extrusion include the use of Supervisory Control And Data Acquisition (SCADA) system, Programmable Logic Controller (PLC) and PC-based control systems.
Praveen Sharma, Proprietor, Hind Machineries, notes, “Today, customers want highly
automatic and synchronised systems to improve their product quality & efficiency and reduce overall costs. Although priced slightly higher, these machines are high in demand, as they help reduce the overhead cost of manufacturers, thus eliminating the need to employ a large number of workers to perform common tasks.”
User-friendly machineryThe main aim of the control system for any equipment in the plastics industry is to provide a simple, but powerful user interface. Its function must be intuitive and easy-to-use; further, depending on the familiarity level of the user, the complexity of the functions can increase. Currently, machines with PC-based control systems are the most operator-friendly machines available in the market. PC-based automation includes a PC platform with Windows operating system. It ensures a host of benefits to the plastics industry, ranging from higher quality parts, through improved equipment uptime, faster cycle time and more predictable production flow to reduce employee turnover. A PC-based system solution offers a style of operation similar to desktop PC applications, which any individual can use today. This has a direct impact on the human-operator performance considering the rules of behavioural science.
Further, software such as colourful Graphical User Interface (GUI) can be installed on PCs, which not only makes machine operations interesting and motivating for operators, but also shortens the learning curve for them. Thus, machine operations become more enjoyable at the shopfloor.
Controllers speakIn a PC-based system, at the press of a button, the set-up person can select a completely different procedure or adopt its function to the required procedure. The ‘simple view’ wide selections of tried-and-tested standard procedures are available to the operator in the controller for different automation applications. The set-up person does not require any programming know-how; he/she can simply select a procedure and adopt the process sequences to the requirements demanded by changing variants. All the settings necessary for a sequence (position, speed
With growing emphasis on automation and demand for operator-friendly machines in the plastics processing segment, many companies in the country are employing machines with PC-based automation or control systems. Avani Jain finds out how the use of such machines helps in reducing the labour costs.

and time) are displayed on a clearly arranged setting page. Commands to be inserted are simply selected from an extensive functions list and placed at the desired point in the sequence. Pressing the symbols in the sequence editor immediately calls up the respective screen page on which the parameters can be set. Even complex sequences can be quickly configured. An operator able to create
movement sequences for linear robots can thus learn to program articulated arm robots within minimum time. Thus, all tasks can be performed by just clicking the button, reducing the need of labour for performing each task manually.
The ‘soft’ware touchOne of the key benefits of process control system based on PC technology is ease of use because the software is running on a familiar platform, and that makes it cost-effective as well. An operator can be trained to use a well-designed touchscreen control system in a few hours. And because these systems are software based, these are more powerful and flexible. PC-based systems are inherently user-friendly and operation can be very intuitive. The biggest convenience for users is the ability to see the ‘big picture.’ Instead of viewing process conditions in isolation, this type of system allows users to readily view data from all equipment from a single, central monitoring station and view that data over time via trending screens.
Human Machine Interface (HMI)Today, machines with PC-based controls come equipped with HMI, which is operator-friendly and easily accessible for process parameters. It provides excellent troubleshooting guidelines, along with the help and alarm menu pages. It has several features: functionally oriented screen
layouts; process parameter monitoring in real-time and feeding value on absolute basis; simple & pictorial diagrams to enable operator understanding; auto temperature and profile selection for homogenous melt from the first shot; extruder over-run for uninterrupted auto cycle; auto heating start, shut down and standby to save time & energy during operation; intrusion insert moulding, gas-assisted interface, core pulling, etc for multitasking utilisation; auto purging for smooth shutdown; mould cooling, mould gate option, sprue break, nozzle shut-off valve, cold slug remove, etc for various applications; as well as smart input/output for uninterrupted production.
Reducing labour dependenceAt present, the controls use microprocessor-controlled high-speed PLC systems, which also help reduce labour cost. Sharma says, “The PLC systems help in reducing labour costs to a large extent, as only one skilled personnel is required to set the parameter once and then the operations can be repeated automatically, thereby minimising manual labour.” Hence, machines with PC-based controls can reduce the labour cost of the company considerably.
Future trendsThe plastics processing industry is in the midst of a transformation in terms of machine construction and system engineering, leading to development of versatile and innovative control technology.
Further, despite increasing complexity, the user-friendliness of the systems and processes not only need to be maintained, but also improved. The operator must only be confronted with a central operating concept and user interface. Therefore, control systems that facilitate integration of peripherals, a uniform operating concept, simple programming and clear representation of complex processes with all important parameters, a high degree of process reliability and comprehensive motoring functions for quality assurance are required to increase the user-friendliness of the machine, which, in turn, will lead to reduction of labour costs.

TIPS & TRICKS: Mould maintenance
94 Modern Plastics & Polymers | July 2012
Regular maintenance can prolong a mould’s life, reduce interruptions, and hence save time, money and problems in the long run. Anwesh Koley lists some pointers that are a must for ensuring proper functioning of plastics machinery through regular maintenance of moulds.
healthy machine lifeto a
Plastics moulding machineryare the most important of all processing equipment, as mould quality is directly
related to the merits of the quality of products. Moreover, as the importance
of the mould during the processing of plastics is high and involves a high cost to the company, these should be paid special attention. Therefore, it is important to spruce up the quality of moulds as well as
their maintenance in order to increase the life of the machinery and ensure seamless output quality.
Email: [email protected] inputs from: Gaurav Anand,
Director, AB Diachem Systems Pvt Ltd
Following are some of the pointers for ensuring regular mould maintenance:
Aluminium or soft tools suffer wear and tear faster than tools made of steel. Plastic materials having fillers are abrasive and wash away the mould steel after some cycles. Plastics with high melt temperature expose the mould to more heat and increase wear. Some materials emit excess residue or corrosive gasses, resulting in the need for regular mould cleaning.
Preventive maintenance should be done every time the mould goes into operation and every time it comes out of the press. Inspection must note small problems and have the repair done. This type of maintenance should be performed by a lead operator in the tool room after about 20,000 cycles, 10 production days or at the end of a production run, whichever comes first.
Use soft or treated water in cooling systems. Blowing out or draining the tool when it is pulled from the machine will enhance its life. Avoid excessive clamp pressures, high injection pressures and over-packing or flashing the mould. The press should not be operated such that the mould is rapidly jerked open and closed, and the appropriate components should be well lubricated.
Extreme care should be taken not to crash the mould closed or close up on partially ejected parts. Seal the work area and mould storage area from the external environment. Moulds with intricate mechanisms or parts requiring unusually high tolerances will require more maintenance than a simple open-and-shut mould, making a low tolerance part.
All components determined and authorised to be replaced should be removed and new components constructed and installed in accordance to the original designs, if previously certified spare components are not available. Worn leader pins, bushings and all bearing moving surfaces such as wear plates and wedge blocks, should be checked for wear and replaced or repaired as required.
In-house tool abuse should be reduced by having a clean operation using well maintained machines and the right tools. One should avoid the use of hard tools such as screw drivers, hammers, punches and knives on any moulding surface, parting or shutoff surface. Use soft tooling like rubber mallets, punches and pliers made from plastics, copper or brass to avoid damaging the mould.

BOOK REVIEW
106 Modern Plastics & Polymers | July 2012
Epoxy polymers are considered as mature polymers since the fundamental knowledge of these thermosetting polymers has been well established during the 1970s and 1980s. The industry, however, continued developing new formulations, processing techniques and applications in the areas of adhesives, coatings & composites, which extend to sectors such as building, electronics, sports goods, automobile and aircraft among others. Towards the end of 1990s, the world had begun to recognise the word ‘nano’, and this book covers the new work done with nanoclays, Polyhedral Oligomeric Silsesquioxanes (POSS), block co-polymers and carbon nanotubes. Serious readers from the industry and students can benefit from this exhaustive compilation.
The book has a chapter on ‘Green Chemistry’ describing different monomers derived from various natural products that are now available commercially. It also has a chapter on thermoplastic epoxies, which can be processed like thermoplastics and cured like thermosets. There is a good inclusion of advanced functional materials such as self-healing, shape memory and transparent opaque transitions with formulations based on epoxy polymers.
EPOXY POLYMERSEditors : Jean-Pierre Pascault and Roberto J J WilliamsPrice : ` 6,595
Polymers are the building blocks of a vast number of natural and synthetic raw materials, which when mixed together and with other materials produce a variety of products such as plastics and resin-based articles, adhesives and many other coating formulations.
Three basic mechanisms, either alone or in combination, can be present in mixing processes. This book briefly describes the mixing equipment and the process where mixing is achieved by a combination of shear and circulation. Blade mixers achieve the mixing by kneading the material continuously, tearing, folding and compressing it between heavy rotating blades. The blades are available in various designs, but are commonly Z-shaped, and while rotating their paths, overlap or cross to achieve the required degree of mixing.
The book gives a view of high-pressure laminates, which play an important role in engineering industries. Other important features include in great detail the high-pressure laminates and copper-clad laminates that are used as printed circuit boards. The topics covered at length in this book are remarkable, such as the use of paints, additives such as anti-oxidant, surfactants, anti-foams, fungicides and curing catalysts. This book is excellent for the library for general information on plastics and resin compositions and even demands space on the shelf of industries even remotely related.

opto-electronic device in the
form of an invisible wall, which
detects any unintentional
movement across it and
signals for use in activation of
protective circuits. This curtain
is mainly used for safety of
the machine operator. The
safety light curtain is used as
an alternative or addition to
mechanical safety system and other form of traditional machine guards.
It is placed between an operator and the machine so that if the operator
puts any part of his body into the machine unintentionally, then some
of the optical beams get interrupted and the receiver generates a trigger
signal for the controller section to stop the machine.
