About us
Heinz Wulfert Maschinenbau is a family-owned company in Velbert that manufactures CNC precision parts by turning and milling all common materials – from bar Ø6–Ø65 mm up to Ø300 mm in the chuck. The production range extends from sheet metal processing with punching, nibbling, bending, brazing and welding to surface finishing through wet and powder painting as well as surface coating. The value chain is completed by the assembly of subassemblies, some of which consist of in-house manufactured parts. Quantities from 20 to 100,000 parts are possible. The quality and delivery dates of all parts are monitored by the QM system according to DIN EN ISO 9001:2008 (certificate CH 11006). The company's products are used, among other things, in automotive engineering, mechanical engineering, construction machinery, mining, gas technology and rail vehicles.
