About HBM
HBM Feinwerkmechanik und Vorrichtungsbau is a master-operated business founded in 1992, based in Lorsch (Bergstraße District, Hessen). The company manufactures machine jig and fixture components, complex fixtures, prototypes, drawing and sample parts, as well as individual parts and small series using conventional and CNC-controlled turning and milling machines. Further services include welding, engraving/marking of manufactured parts, standard part procurement, as well as maintenance and overhaul of industrial machines and components. Materials processed include structural steels, alloy steels, stainless steels, common non-ferrous metals, and plastics, which are available short-term from a well-stocked inventory. Surface finishing, heat treatment, as well as thread drawing, eroding, laser technology, waterjet cutting, and burning are offered through long-standing partners. Customers come from the food industry, the automotive industry, and the agricultural and construction machinery sector. Since 2018, Marc Stumpp, a master machined mechanic and state-certified business manager of crafts, has led the sole proprietorship as owner and CEO.
