It is extensively used in aerospace, medical and automotive industries and is now readily available through Overmould, Henkel’s UK partner. In house design, consultation, pre-production services and demonstration facilities are based in Bedfordshire, England, as well as machine sales, material sales and expertise, service and support.

TECHNOMELT is increasingly used in industry to achieve cost and performance advantages. As a robust alternative to traditional potting and encapsulation techniques, TECHNOMELT brings improved reliability, reduced manufacturing times and ultimately superior products.

TeCHnOmelT PolyamideTECHNOMELT is a unique polyamide designed for the electronics industry. It delivers exceptional insulation properties, great physical strength and excellent adhesion to cable sheaths, metals, plastics and other materials.

low pressure injection of TeCHnOmelT polyamide for electronics encapsulationTECHNOMELT® polyamide provides advanced protection for electronic circuitry in tough environments. In just one or two mould steps, assemblies can be converted from delicate electronic structures to robust, ready to market products. The automated processing, throughput and cure time advantages that TECHNOMELT delivers simply cannot be matched by older-generation encapsulation methods. Low pressure moulding provides mechanical integrity, protects solder joints from vibration fatigue and the entire assembly from the atmosphere and liquids that could promote corrosion or conductive paths.

Technomelt comes in black, amber or clear - with other colours available through secondary processing.

Because of the unique characteristics of TECHNOMELT the applied mould pressure is very low compared to injection moulding, and so the mould process is gentle on electronic structures - even surface mount components and lead free soldering is safe! Low mould pressure also enables the use of aluminium tooling so project costs are drastically reduced and lead times are cut. Even small batch sizes can take advantage of the many benefits of overmoulding.

Designers understand that the advantages of TECHNOMELT go beyond simple enclosures including fixings, strain relief and product identity. Low pressure moulding encases, seals and adds value in one operation.

Designing with TECHNOMELT has become state of the art across many electrical and electronics industries increasing reliability, product performance, profit and competitiveness.

versatile application

TECHNOMELT is a strong adhesive and will bond with many substrates. For instance, the grip onto PVC is excellent, making it perfect for sealing and anchoring cables. TECHNOMELT also bonds to clean steel, solders and other metals commonly encountered in electronic modules. In fact, in our experience, nothing sticks better!

When cool, TECHNOMELT is tough retaining slight flexibility below zero degrees yet good rigidity to 130 degrees or even higher with selected variants.

Electrical insulation is excellent at typically 1012/cm and the dielectric strength is 20kv/mm.

High performance technical poyamide

Low pressure overmoulding of electronics provides a mechanical integration that enables fewer parts, higher reliability and cost savings. By creative involvement during the design phase, other benefits may also be enjoyed such as increased perceived value, additional functions, security of IP, electrical insulation and improved user friendliness.

Product advantages with TeCHnOmelT

TECHNOMELT is a high performance technical polyamide designed to flow at low temperatures, and therefore low pressures. Delicate electronic structures can therefore be encapsulated without disturbance. The tooling can be made from aluminium, reducing costs and shortening lead times. Applications include component protection, reliability enhancement, insulation and security, whilst adding mechanical features and product appeal.

Advantages of two-stage moulding

Many applications require only one injection process to complete. Some applications that are highly complex often benefit from two stages of moulding. The first for primary or bulk encapsulation, the second to ensure a uniform all-round thickness, coverage and finish. Both stages can often be incorporated into a single mould tool.

low pressure overmoulding improves product performance

TECHNOMELT is increasingly used in automotive, aerospace, medical, and communication industries to achieve cost and performance advantages. By rethinking conventional packaging and eliminating potting and traditional encapsulation, TECHNOMELT, together with low pressure moulding, delivers improved reliability, reduced manufacturing time and improved product performance.
