Die forging

Forming of highly stressed components

The compressive forming process of die forging can be used for manufacturing highly stressed components with and without flash. It is a highly productive manufacturing process primarily used for large batch sizes. The investigations regarding die forging are mainly closely related to the corresponding forming unit, tool system technology and the materials to be formed. In particular, subsequent processes such as pre-forming (cross rolling) are included in investigations of the entire process chain as part of the technology development. In this context it is possible to individually adapt the specific operational conditions and requirements.

  • Material efficiency due to joined initial forging shapes
  • High performance tools with quick-change system for cartridges
  • Special materials in hot bulk metal forming
  • Material composites for large engines in shipbuilding

  • Resource-efficient forming process for manufacturing complex components with optimal exploitation of raw material       
  • Die forging can be used as forming process for almost all materials (e. g. conventional steel materials, aluminum and magnesium wrought alloys, nickel-base alloys and titanium alloys)
  • Highly productive manufacturing process with short process times and high automation level of the forming process chains, including temperature finishing treatment of the unmachined forged components
  • Warm forming as energy-efficient process in mass production, particularly for enhancing the microstructure and for reducing the tolerance range of the unmachined forged components
  • Precision forging as special process of hot bulk metal forming for workpieces with highest demands regarding their component properties (dimensional properties, mass characteristics, delicate features)
