Diehl Metal Applications (DMA) is your partner for sustainable metal and hybrid solutions throughout the entire value chain — from precision stamping technology and surface finishing to overmolding and complex metal-plastic composite systems and battery solutions.
With our state-of-the-art manufacturing capabilities, in-house toolmaking facility, and comprehensive development expertise, we create custom products for tomorrow's mobility and drive concepts — reliably, efficiently, and sustainably.
From press-fit zones ensuring secure PCB connections to functionally integrated metal-plastic hybrids, high-performance cell contact systems (CCS), and modular low-voltage battery solutions – we deliver precision, functionality, and efficiency. Our CCS are highly adaptable to different cell formats and power ranges, supporting both low- and high-voltage applications.
With over 50 state-of-the-art stamping lines, one of Europe’s largest surface treatment facilities, and fully automated production processes, we provide uncompromising quality – from prototype to full-scale series production.
Leveraging our experience in the automotive, electrical engineering, telecommunications, and industrial applications sectors, we collaborate with our customers to design the technologies that will enable future mobility, energy, and communication.
Since 1959, Diehl Metal Applications has been developing and manufacturing high-precision punching, cutting, and bending tools at its own toolmaking centers in Teltow (Germany) and Besançon (France). We specialize in module technology and the assembly of complex precision tools. Thanks to the use of carbide, our tools boast particularly long service lives, high productivity, and reliable processes.
At Diehl Metal Applications, we develop and manufacture along the entire value chain.
Our in-house metal management enables us to optimally match the base material and surface coating. Our customers and partners can choose whether to use partial solutions and provide the material themselves, or hand over the entire process to us.

At Diehl Metal Applications, quality is our top priority. In line with our zero-defect philosophy, we consistently test all products for maximum precision and reliability. Our quality control process covers every stage of the value chain, combining state-of-the-art testing methods with seamless monitoring of processes.
We combine state-of-the-art injection moulding and overmoulding simulation with practical manufacturing expertise. By conducting precise filling studies and warpage and shrinkage analyses, as well as optimising tool design, cooling and process parameters, we can identify potential sources of error at an early stage and ensure efficient, stable production. Live data monitoring, process verification and reverse engineering guarantee the highest quality and traceability, from prototype to series production.
With our products for the areas of eSolutions and Electrification, we enhance the implementation of sustainable drive technologies. As an electroplating company, we have a special responsibility for the environment, which we take into account, for example, with state-of-the-art water treatment plants, in order to achieve our long-term goal of 'zero emissions'.
