Production line for heat treatment of fasteners and automotive parts
Fasteners can be found in almost every industrial sector, for building construction, equipment manufacturing or automotive applications, where fasteners are an important assembly part. Screw and screw nut are the classic fasteners which have to last to high mechanical stress without getting damaged or any other defects. Gears must stand also high mechanical stresses. Modern gearboxes have to overcome this type of issues without any problem. In order to have high quality parts you also need high quality equipments. For manufacturing these elements, the product must go through several processes as the hardening process, the quenching and annealing process. We offer modern equipments and complete production lines from Asian manufacturers but also custom made equipments at competitive prices.
