About Röttinger Metallgießerei
Röttinger Metallgießerei GmbH is a customer-oriented foundry in Röttingen near Würzburg producing castings made of aluminium and copper casting alloys. The portfolio includes sand castings produced by hand and machine moulding (HWS flask moulding machine, flask size 800x650x250/250 mm), gravity die casting, full mould casting (lost foam), and centrifugal and continuous casting for rotationally symmetric parts such as bushings and rings up to 2000 mm outside diameter. Aluminium sand cast parts are produced from 0.2 kg to 800 kg, copper castings up to 150 kg unit weight; series parts up to 10,000 pieces per year are possible. In addition, the company offers heat treatment of non-ferrous casting alloys, surface treatment by sand, steel and glass bead blasting, as well as mechanical finishing up to 4000 mm component length. Customer industries include, among others, mechanical and plant engineering, the food industry, the brewing industry, wood processing, the automotive industry, gearbox manufacturing, organ building and household appliances.
