About RAMPF

The RAMPF Group was founded in 1980 by Rudolf Rampf in Grafenberg and today develops as an international family business with approximately 900 employees solutions in four areas: reactive casting resin systems for sealing, casting, gluing and shaping; automated mixing and dosing units for reactive plastics such as polyurethane, epoxy resin and silicone; machine beds and frame components made of mineral cast, UHPC and hard stone; and lightweight parts made of CFRP and GFRP. Manufacturing includes vacuum casting, CNC milling of block materials, precision grinding and lapping, resin infusion, VARTM, TFP and hand layup, as well as assembly of modules with cable and media integration. Customers include the sectors of electromobility, automotive, aerospace, electronics, mechanical and plant engineering, medical technology, and foundry. In addition to the headquarters in Grafenberg, the group manufactures in Wangen bei Göppingen, Zimmern ob Rottweil, Burlington (Canada) and Wixom (USA).
