Coating Techn­ology

The whole world of coating technology

In Pforzheim, Germany, DODUCO develops products and processes for surface treatments. Our products are used in applications for the electrical industry (printed circuit boards, ceramic substrates, contacts in power electronics), equipment manufacturing, automotive industry, renewable and alternative energy, industrial drives and medical technology. All the most common processes in parts electroplating, reel-to-reel plating and PVD are available as job-shop services.

Plating of metal strips

Strips can be solid, pre-stamped or belt-linked. Strips and stamped parts made of copper and copper alloys, nickel and nickel alloys, stainless steel or beryllium/bronze and can be coated additionally hardened or annealed.


Electroplating is used for fine and hardgold, silver, palladium/nickel, copper and nickel as well as pure tin and tin/lead alloys. The dimensions of the base material strip depend on the process used; thicknesses range from 70μm to 2mm and the maximum width is approx. 120mm.

Stripe plating technologies

Dipping process
Plating of the entire surface or selective two-sided plating of solid or stamped strips
Stripe plating
Stripe plating of solid strips using wheel and masking techniques
Selective plating
Selective single-sided plating of prestamped parts using brush plating techniques
Spot plating
Spot plating of contact surfaces on pre-stamped or punched strip and grids

Parts plating

Our areas of expertise include plating a wide variety of metallic materials both with precious metals such as gold, silver, palladium and rhodium as well as with base metals such as tin, tin/lead, chemically applied and electrolytic nickel coating and electrolytic copper plating.


In addition to the conventional substrate materials of copper and copper alloys, we can also apply strongly bonded coating to aluminium, high-alloy steels as well as to more specialized materials.

Barrel plating
Bulk items can be plated with many diffent combinations of layers of varying thicknesses. In each case, the most suitable electroplating unit and production line are chosen to match the geometry of the parts and the batch size.
Rack plating
New products and parts with complex geometries impose special demands on the production of workpiece racks and jigs to ensure that the required layer thickness is deposited even on less accessible areas of the product. To meet this requirement, DODUCO has its own rack and jig construction department.


As the perfect complement to and extension of our electroplating services, we also offer PVD (Physical Vapour Deposition) coating services. This process enables even non-conductive substrates such as plastic, ceramic, glass and titanium based materials to be coated.

In addition to silver, hard gold, palladium, platinum, copper, nickel and chromium, coatings can also be made of materials which cannot be deposited by means of electrolysis, such as tungsten, titanium, aluminium, titanium nitride, alloys and composites.
