About Dörrer AG
Dörrer AG is a family-owned metal finishing company in Zurich, founded in 1935 during the Great Depression. The company offers a broad range of electroplating and chemical surface treatment processes, including electroless and electrolytic nickel plating, chromium plating, gold plating, copper plating, technical silver plating, zinc plating, tin plating, phosphating, passivation, and pretreatments. Metal workpieces from customers in various industrial sectors are finished. Since 1942, production has been located at Giesshübelstrasse 108 in Zurich; previously, the company was based at Kohlengasse 24. The company has been ISO 9001 certified since March 2003 and is a member of the Swiss Society for Surface Technology (SGO).

Processes & Materials
Electrolytic Nickel Plating
Electrolytically deposited nickel layers for corrosion and wear protection of metal parts.
Electroless Nickel Plating
Chemically reduced nickel-phosphorus layers for uniform coating thicknesses even on complex geometries.
Chromium Plating
Hard or decorative chromium layers for wear protection and appearance.
Zinc Plating (Blue, Yellow)
Zinc layers with passive blue or yellow chromate conversion as corrosion protection.
Technical Silver Plating
Technical silver layers for electrical conductivity and contact capability.
Gold Plating
Gold layers for contact reliability, corrosion protection, and electronics requirements.
Copper Plating
Copper layers as intermediate or conductive layers in plating stacks.
Tin Plating
Tin layers for solderability and corrosion protection.
Passivation
Passivation of stainless steel and metal surfaces to improve corrosion resistance.
Phosphating
Phosphate layers as corrosion protection and adhesion base for subsequent coatings.
