The automotive supplier

Everything from toolmaking to serial manufacture

www.muhr-metalltechnik.de

32

As supplier to the automotive industry, we focus on the

following main areas of activity: Manufacture of punching tools and drawing dies

Serial production of pressed components made of steel and aluminium, which are further processed to welding assemblies

Manufacture of tube stays

Production of seats for special vehicles

Experience and flexibility

As a family-managed SME based in Wenden in the Sauerland

region, we have extended our manufacturing capacity contin-

uously, so that today we can offer our customers optimized

all-round solutions from the design of components through to

serial manufacture on a large scale.

We stand for flexibility and reliability, and we have a wealth of

experience in our key areas of expertise – forming and weld-

ing technology.

Economical, speedy and precise

We work in close cooperation with our customers at an early

stage – even in the development of parts and tools. A holistic

view of the process, taking economic considerations into

account, is something we see as self-explanatory. With the

help of our system partners we realize every customer

request – the methodological planning, design, drawing simu-

lation, construction of prototypes and tools as well as subse-

quent serial production.

Development and design

... by experienced members of staff

The manufacture of tools and prototypes at a high level of

expertise is our speciality. A modern pool of machines, com-

bined with experience and the manufacturing skills of our

employees, are the guarantee of our success in working with

our business partners. The consistent further development of

our powerful toolmaking facilities is definitive in underpinning

the innovative strength of our company.

ProductionToolmaking

Punching

Our recently built production plant uses state-of-the-art auto-

mated punching machines, with a press force of 200 to 1100

tons. Strip processing lines for coil widths up to 1700 mm,

efficient tool changing systems and a central scrap disposal

scheme guarantee economic manufacturing operations with

the best possible cost-benefit ratio.

In 2011 we put our first servo press into operation – a 630 ton

Monoblock machine. The direct drive with servo motors used

here offers significant advantages for the output of compo-

nents.

The lengthwise division of the steel coils to the required

dimensions is effected for the most part by our own splitting

plant.

Innovative and optimized Our toolmaking division specializes in the production of

stepped tools, progressive composite dies and transfer tools

for car body parts made of steel or aluminium. We have a

base of longstanding satisfied customers, including highly

regarded manufacturers like Daimler and BMW.

For deep drawing, punching and pressing operations we use

tools with a total weight of up to around 35 tons.

Progressive composite system

In working with our customers and system partners we rely

on the CAD/CAM programs CATIA V5, MASTERCAM and

WORK NC. Inspection approvals in preparation for serial manu-

facture, initial trials and preliminary production can all be

effected using the hydraulic and mechanical presses present

on our premises. Our toolmaking department is located right

next to the production plant, shortening transit times and

making it easy for us to maintain and service our production

equipment.

Welding and cutting

Manufactured pressed parts are joined together to form mod-

ules and assembly groups, using a many different welding

systems. Our machinery pool consists of manually operated

resistance and welding machines, MIG/MAG welding robots

and fully automated universal point welding systems.

One of our specialities in the field of joining technology is the

production of parts for special vehicles, which meet the high-

est individual requirements. With a view to being able to deal

with the most demanding customer specifications, Muhr

Metalltechnik has invested in a powerful 3D laser cutting

plant.

Production

Hydraulic deep draw presses

Manzoni 800 t Triple-acting Press force 8000 kN Table area 3200 mm x 2000 mm

Gräbener 630 t Triple-acting Press force 6300 kN Table area 2600 mm x 1500 mm

Gräbener 480 t Double acting Press force 4800 kN Table area 2250 mm x 1400 mm

Gräbener 400 t Press force 4000 kN Table area 1500 mm x 1000 mm

Deep drawing

We use various double-acting and triple-acting hydraulic deep

draw presses with a press force ranging from 400 to 800 tons

to make large-scale deep draw components, like tank covers,

car body reinforcements, tube stays and decorative screens.

A speciality of ours is the production of doors for the driver’s

cabins of lorries.

With smaller batch sizes, phase changes are effected by

manual insertion of the components. Our toolmaking depart-

ment makes use of the hydraulic presses already present on

site for initial trials and preliminary production.

Quality as a philosophy

Use of the most up-to-date equipment in the production pro-

cess (including state-of-the-art measuring systems) ensures

that all customer requirements can be fulfilled in the best pos-

sible way. Central contact persons, network-supported plan-

ning and working procedures with ISO/TS 16949 and

DIN ISO 9001 certification guarantee the outstanding quality

of our products and services.

The constant endeavour to improve our quality and boost the

satisfaction of our customers is a fixed pillar of our corporate

philosophy.
