Electroplating of strips & parts

Diehl Metal Applications (DMA) stands for innovative coating technology and galvanic surface finishing at the highest level. With a wide range of electroplating processes, we develop and implement customized surface solutions for the requirements of modern industries - from the automotive industry, telecommunications and medical technology to mechanical engineering, electrical engineering and electronics.

Our surface coatings are not only used for finishing, but also fulfill functional requirements such as corrosion protection, wear resistance, solderability and electrical conductivity. Thanks to state-of-the-art systems, precise process control and decades of experience in electroplating, we ensure consistently high quality and a long product service life.

Whether selective electroplating, high-precision contact finishing or special functional coatings - Diehl Metal Applications offers everything from a single source: from development and sample production to series production. In this way, we support our customers worldwide in optimizing components, reducing friction losses and increasing efficiency and reliability.

Our product portfolio

Diehl Metal Applications offers a comprehensive technology portfolio in the field of electroplating and surface finishing. This enables us to meet individual customer requirements in a reliable and performance-oriented manner - from standard solutions to highly selective or specialized processes.

Our range of services includes

  • Strip finishing of belts - precise electroplating of multi-track belts for different functional zones
  • Coating of precision stamped parts - including stamping grids, individual and small series parts with selective coating application
  • Coatingof connectors - springs, sockets and pins are plated for optimum conductivity and corrosion protection
  • Single-sided coating of contact springs - for optimized functionality and reduced material costs
  • Internal coating of closed contact springs - highly selective gold plating inside the components for maximum performance
  • Special coatings for press-fit zones - tailor-made surfaces for mechanically stressed areas, optimized for lead-free applications

 

Thanks to this variety of electroplating processes, selective technologies and special coatings, DMA offers its customers tailor-made solutions for the most demanding requirements in electronics, automotive, medical technology and mechanical engineering.

Quality assurance

Highest surface quality is a central requirement at Diehl Metal Applications. To ensure the long-term quality of our electroplated coatings, we rely on state-of-the-art testing and analysis technologies. This allows us to monitor every step of the coating process precisely, reproducibly and with full traceability.

Our quality assurance at a glance:

Scanning electron microscopy (SEM)

  • Visualization of the finest surface structures
  • Analysis of coating morphology, pores and defects

X-ray fluorescence analysis (XRF)

  • Precise, non-destructive measurement of coating thicknesses
  • Inspection of material composition and layer structures

High-resolution camera systems

  • Automated visual surface inspection
  • Detection of irregularities, scratches or inclusions

Holistic process monitoring

  • Ensuring homogeneity, dimensional accuracy and reproducibility
  • Seamless documentation of all quality parameters

Our commitment to sustainability

  • Sustainable precious metal recycling

    Diehl Metal Applications closes the precious metal cycle directly in production: gold and silver from electroplating are efficiently recovered and recycled. In this way, we save valuable raw materials, reduce CO₂ emissions and strengthen the circular economy - for more sustainable coating technology.

  • Waste water & treatment - responsible and process-safe

    Diehl Metal Applications guarantees maximum process reliability through continuous quality monitoring of the electroplating baths. Electronic control systems and precise analytics ensure stable coating conditions and reproducible results. At the same time, all waste water is specifically monitored and treated in order to conserve resources and reliably comply with environmental standards. This is how we combine technical precision with responsible environmental protection.

We think holistically

  • Product and process development

    Innovative products require stable, precisely controlled processes. In product and process development at DMA, we rely on state-of-the-art analysis and automation technologies.

    A central component is the use of automated pipetting robots, which are used for the precise analysis and monitoring of our electroplating chemistry. They enable reproducible measurements, maximum accuracy and rapid evaluation of complex chemical parameters. On this basis, we continuously develop and optimize our coating processes - for consistent quality, process reliability and customer-specific solutions. Our comprehensive analysis options form the foundation for sustainable innovation and technological excellence.

  • Integrated value creation

    Diehl Metal Applications develops and produces customer-oriented complete or partial solutions along the value chain:

    Our customers and partners can choose at any time whether they want to take advantage of partial solutions and provide the material themselves or hand over the complete process to us.
