About Karl Kampka Oberflächentechnik
Karl Kampka Oberflächentechnik is a company in Fürth (Burgfarrnbach) that has been performing chemical surface treatment of metal for more than 35 years. The company treats workpieces made of iron and steel, in particular by blackening (burnishing) to DIN 50938 or in-house standards and phosphating to DIN EN ISO 9717. The service portfolio also includes mechanical and chemical pretreatments (pickling), tumble finishing (Trowalizing), post-treatments by dipping in oil-water mixtures for corrosion protection, and tempering to reduce hydrogen embrittlement. Individual parts and mass-produced parts are processed, complemented by assembly and contract work as well as a collection and delivery service. More than 40 employees work on over 3,000 m² of operating floor space. Finishing services such as zinc plating, brass plating, copper plating or nickel plating are offered via the cooperation partner GAZIMA Galvanische Veredlung Zimmermann GmbH.
