Hot forming / closed-die (drop) forging

Custom bolts and closed-die (drop) forgings up to 30 kg are hot-formed. Depending on requirements, the components are machined, quenched and tempered, coated and delivered complete and ready for installation.

We manufacture custom and standard bolts hot-formed up to M64 and a maximum length of 500 mm — to DIN 261, 609, 610, 912, 931, 933, 960, 961, 6912 and 7991, in strength classes 3.6 to 12.9.

Materials

What regularly goes through our forge and presses

We process all common materials for mechanical engineering, plant engineering and vehicle manufacturing. Special grades according to specification available on request.

  • Free-cutting steels – e.g. 11SMn30, 11SMnPb30: for cost-effective series production with high machinability
  • Quenched and tempered steels – 25CrMo4, 42CrMo4, C45: for shafts, bolts and highly stressed components
  • Case-hardening steels – 16MnCr5, 20MnCr5: for case-hardened functional surfaces
  • Stainless steels – 1.4301, 1.4404, 1.4571: corrosion resistant, food-grade
  • Aluminium & special alloys – e.g. AlMgSi1, AlCuMgPb: for lightweight, corrosion-resistant parts
  • Non-ferrous metals – CuZn39Pb3 (brass), CuSn8 (bronze), copper: for bearing bushings and electrical applications
  • Plastics – e.g. POM (Delrin), PTFE (Teflon): for sliding and chemically resistant applications
