About us
HJT GmbH from Schloß Holte-Stukenbrock manufactures metal parts that cannot be produced in mass production due to their shape and use. Originally rooted in toolmaking, the company today operates on four pillars: motorsport, toolmaking, special engineering and prototype construction. The portfolio includes special parts for historic racing such as wheel hubs, drive shafts, gearbox gears and centre nuts as well as the construction of new injection moulding tools including repair, modification and maintenance. Turning, 3D milling, wire and sinker EDM, laser welding and grinding make up the daily production work; 3D design and 3D CAM programming complete the process chain. The company is fully geared to single-part and small-batch production and supports customers through to series production. Heat treatment and coating are procured via an established partner network; common motorsport materials are kept in stock.
