Diehl Metall – Know-how in efficient technologies

Composing metal competence

Diehl Metall is an international technology manufacturer of rods, tubes and profiles, synchronizer rings made of high-tensile brass and steel and metal-plastic compound systems. The company is world leading supplier with its own fully integrated supply chain. The trends of the future have been identified. Diehl Metall operates in the fields of metal purchase, material development, integrated production of stamping and plating, overmolding and assembling, sheet metal forming and forging – completely in-house. From the start, we place great value on easily recyclable alloys and composite materials. With our new copper alloys, like Ecobronze BB05xi, material costs can already be reduced during the component design. New cost-efficient ways of recycling are introduced. The active recycling-system of Diehl Metall leads to savings in raw material right from the start and helps to minimise the access to primary resources.

Economic production process as system supplier

Due to the right selection of material, effective stamping and plating technologies, integrated overmolding and assembling as well as adapted processes to each product, we are able to meet all requirements and at the same time an economic reduction process can be realised. In collaboration with our customers and partners, Diehl Metall develops individual solutions for special applications and customized prematerials and components in order to select the appropriate material as well as to specify customized material combinations and production processes.

Toolmaking

Toolmaking

Quality, precision, production reliability and high production rates can only be achieved through optimum interaction between product development and tool manufacture. The Diehl Metall project management is focused on the most modern aspects and benefits from our long-term experience gathered over decades in the manufacture of sophisticated tool and fixture concepts. Even in the stage of product development we are able to work out flexible solutions and react to customer demands at any time. The short-term supply of prototypes and small series can be realised as well. Thus, Diehl Metall ensures an optimum process and project development.

Forming Competence

Forming Competence

Compared to open-die forging, the workpiece is almost completely enclosed by the tool in the drop-forging process. The production of drop-forged parts made of brass is assigned to the production process of warm forming within the massive forming. In comparison with massive cold-formed workpieces, warmed-formed parts are advantageous because of their significantly higher degree of forming. Moreover, they offer – compared with chipped components – the advantage of much lower material input and at the same time much more complex shapes can be produced.

Precision Stamping Technology

Precision Stamping Technology

The functionality as well as the production reliability of the finished product is determined in the stamping technology. At this point the course for all further steps is set. This is why we focus on uncompromising precision in our stamping technology due to our highly-developed automation process using optical and electronic monitoring. With its ultra-modern stamping machines and its own toolmaking and engineering, Diehl Metall provides precision stamping technology for sophisticated precision stamped parts in large numbers. Of course, we deliver our precision stamped parts with any full- or partial-surface plating that is required by our customer.

Plating Technology

Plating Technology

Special surface coatings solve the conflict between the technological requirements for the base material and the conditions of use in many cases. Diehl Metal Applications offers an entire electroplated, thermal and metallurgical finishing process as well as its combination. An economic use of high-quality plating with precious metals can be achieved with modern selective techniques. Because of appropriate plating technologies, the precious metal used for contact and bonding surfaces is substantially reduced. Moreover, the DMA is able to detach gold targeted from surface elements and win it back. This precious metal-recycling-process MEGER® was awarded the innovation price of Berlin-Brandenburg.

Overmolding & Assembling

Overmolding & Assembling

Different strengths of diverse materials can be used in a targeted way in the overmolding and assembling technology. Due to an optimum material selection, products of high quality result. At the same time the component is engineered in such a way that the customized solution with optimum material input for each application can be developed. Development capacities as well as testing and laboratory facilities support this.
