About Beinbauer Group
Beinbauer Group is an integrated provider of casting and machining solutions with five locations in Germany and the Czech Republic. At the Schwerte site (Beinbauer Casting), complex iron castings with nodular and flake graphite are produced in weights from 15 to 400 kg – from solidification simulation through patternmaking, core and mould making to machining. At the Büchlberg, Obernzell, Kelberg and Sporice sites, cast and forged parts are machined on more than 300 machines: 3-, 4- and 5-axis milling as well as turning for part sizes from 30 to 1,250 mm with a maximum clamping mass of 2 t. The service portfolio includes technical consulting, toolmaking, in-house fixture construction, coating via a partner network, assembly and supply chain management including JIT/JIS delivery. Customers come from the commercial vehicle, agricultural machinery, construction machinery and rail technology sectors. With the planned electric melting operation (GREEN CASTING, production start 2027), the company is reducing its Scope 1 emissions by around 90%.
