Composing Plating Technology

Quality. Not only on the surface.

New materials and increasing complexity of applications set the highest standards to 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.

Selective plating by Diehl Metall – savings in material for a better energy efficiency

In many cases, especially surface plating solves the conflict of interests between technological requirements to the material and its operating conditions.
The most modern selective techniques enable an economic use of high-quality plating with noble metals. The input of noble metals for contact and bonding surfaces can be decisively reduced by appropriate plating technologies. As a result the materials are only used, where they are really needed.

Furthermore, Diehl Metal Applications offers the possibility of detaching gold from surface elements selectively and thus, winning back the gold. This noble metal recycling-process MEGER® was awarded the innovation prize of Berlin-Brandenburg.

In terms of energy efficiency Diehl Metall provides high-performance alloys made of recyclable surfaces and highly heat-resistant materials for connectors.

Diehl Metal Applications provides an extensive technology portfolio for the surface treatment: Stripe plating of strips (even with different noble metals), plating of precision stamped parts (leadframes, stamped parts), plating of connectors (contacts, sockets, pins), single-sided plating of contacts, internal plating of closed contacts, plating of systems and press-fit zones for several products.

Diehl Metall – quality non-stop – national and international

The business unit Diehl Metal Applications possesses extensive know-how for technically and economically optimised plating technologies for every purpose. This know-how is combined with high-performance plants. Individual surface plating, such as selective plating with precious metals, are able to save the scarce resources. Based on the customer needs our process engineering develops and optimises our plating technologies. Therefore we can offer an optimum service to our customers at any time. Thus, we are in the optimum position to provide customized solutions for the increasing market challenges.

Two locations of the Diehl Metal Applications owe together one of the largest machinery for surface finishing in Europe:

  • Diehl Metal Applications (Germany)
  • Diehl Power Electronic (France)

As a result we are able to react flexibly on requested dates of delivery and capacities. You receive individual product solutions developed by our international production and development teams. Due to electronic monitoring as well as analytical control we obtain exactly defined functional properties at the highest level. Strips, wire or leadframes are plated, fully or selectively.

One-Stop-Shop: reduction of complexity and costs

Customers benefit from the Diehl Metal Applications One-Stop-Shop:

  • Casting of alloys
  • Rolling of strips
  • Strip plating
  • Precision stamping technology
