3 FOUNDRY TECHNOLOGY 2 3 Casting on highest level Since the company foundation in 1708 components of metallic materials are cast. Besides an iron and steel a bronze foundry was erected around Nowadays mainly sand castings of copper and copper alloys are produced but also castings of high and low alloyed steels and nickel alloys. For the hand- or automatically formed parts resinoid-bonded sands are used. This ensures an excellent surface as well as very close tolerances. Components with special requirements can be cast as per the shell moulding process using ceramic moulds and ceramic cores. Castings of copper alloys can be realized up to unit weights of abt. 7,000 kgs and up to abt. 1,200 kgs of steel. A well equipped machine shop with latest CNC lathes allows pre- or finish-machining of castings as per customers drawings. In the laboratory and testing department all destructive and non-destruc - tive tests and examinations are possible. Our production is certified to DIN EN ISO 9001 : Quality and service are our basis for successful work on the national and international market.
