Metal-plastic compound systems

Read more

The best of two worlds.

Metal and plastic were seen as competitors in industrial production for a long time. The overmolding and assembling technology ended this once and for all. At the same time a wide space for innovations, technically sophisticated concepts and varied new challenges arised.

Sustainable solutions start at the beginning of the supply chain.

Like no other material copper alloys as prematerial meet the highest standards of flexibility and strength, bending and stamping as well as thermal and electrical conductivity. Our prematerials are formed to durable and modern products. The sustainable Diehl Metall recycling system provides efficiently used raw materials.

Synchronizer Rings

Always one gear ahead.

Transmissions ensure driving dynamics. The keystone of the mechanical transmission is the synchronizer ring. Whether synchronizer rings out of metal or steel, with or without friction layers: Diehl Metall shapes mobility actively. Has been for more than 55 years with 150 different types of synchronizer rings now. In almost every gear box vehicle is a synchronizer ring of Diehl Metall.

Drop-forged Parts

We highlight your day.

Diehl Metall droped-forged parts made of brass, lead-free copper and light-metall materials function not in plain view. They are a part of daily life. Especially where you least expect it. Diehl Metall droped-forged parts are in demand with the traditional industries as well as with the customers who indulge in modern mega trends like water, health, green technologies, mobility and energy.

Stamping Technology

Read more

Stamping and bending. Instead of bending and breaking.

Precision stamped parts are important elements in a variety of electronic and electrotechnic applications. The functional reliability as well as the quality in manufacturing of the final product play a decisive role in stamping technologies. The foundations for all further steps are made here. In our stamping technology we therefore count on uncompromising precision with highly developed automated processes.

Rods, Tubes, Profiles

Brass incognito

Rods and tubes by Diehl Metall in different shapes and dimensions are the direct link between raw material and final product. Not only do they offer a comfortable processing but also enable high efficiencies in subsequent products. Being hidden under a bright surface our rods and tubes made of over 60 alloys do not function in the plain view, but fit perfectly to every purpose.

Creating a piece of future day by day. Since 1902.

Alloys increase product life and efficiency while providing a positive energy and climate balance of the products. In coordination with our customers we research, develop and produce alloys for modern life and create a piece of future day by day. An extensive range of alloys as well as experience of more than 100 years are what make us special.

Plating Technology

Read more

Quality. Not only on the surface.

New materials and increasing complexity of applications place highest standards to the plating. Progress in electronics and electrotechnics is hardly to imagine without plating. Whether wear resistance, solderability, corrosion resistance or conductivity – thin surface finishing ensures security and long product life.
