Product advantages

  1. Optimal component strength for secure power transmission
    Our forgings have a continuous grain flow and can therefore absorb and transmit very high forces.
  2. Precision work according to customer specifications
    In cooperation with our customers, we can forge nearly all components, create weight-optimised designs and offer our support during the machining process.
  3. Diverse design options
    The forming processes are selected based on the technical requirements of the products and machining processes.
  4. High-tech processes for high precision
    Specially developed processes – ring rolling and wedge rolling – allow for the production of complex parts.
