Forging / Rotary Swaging


The segments of the forming tool (2, 3 or 4 split molds) apply pressure radially on a turning part. With the help of a corresponding tool segment design, various part designs can be formed. Depending on the forming degree, the process will be executed in cold or hot condition.

The forging technology can be used for steel, aluminum, copper, titan and other metallic materials.

Advantages of Forging / Rotary Swaging


  • Weight reduction: The forging / swaging technology offers the possibility to define a specific wall thickness distribution, especially when it comes to weight-critical parts e.g. in cars. Very often it comes to the replacement of bars by tubes while integrating the forging technology.
  • Material savings: By using the forging technology and the corresponding shift of material, parts can be formed to defined geometeries without any loss of material. The real material usage can be reduced significantly.


  • Safety: Parts, which are produced by reducing / expanding, do generally present a more homogenous fiber flow. Based on the uninterrupted fiber flow, parts can be exposed to higher forces in comparison to parts, which are produced by machining.
  • Quantity reduction of single components: Products, which were so far welded together out of several single components, can now be formed out of one single semifinished part. This results in a tremendous cost reduction for stock-keeping and provisioning of single components.
