About Herbert Bauer
Herbert Bauer GmbH & Co. KG is a service and industrial company for surface treatment founded in 1950, headquartered in Obernzell (Lower Bavaria). At the site, around 400 employees process up to 400 tonnes of material daily. The range of services includes electroplating such as acid and alkaline zinc, zinc nickel, nickel plating, tin plating, silver plating and copper plating, as well as surface and coating processes such as KTL, powder coating, wet paint, multi-layer systems (duplex/triplex), Geomet® zinc flake, electroless nickel and phosphating. In addition, the company manufactures components mechanically: 2D laser cutting (3000x1500x25 mm), CNC bending, dual-robot MAG welding, 5-axis milling, CNC tube bending, as well as assembly and kitting. Steel, stainless steel, aluminium, copper, brass, bronze and non-ferrous metals are processed. As part of the KFB Surfaces group, Herbert Bauer primarily supplies the automotive, commercial vehicle, mechanical engineering, agricultural machinery, electrical industry, construction and plant engineering sectors in Germany, Austria and the Czech Republic.
