stable current voltage curves with a well marked ne- gative differential resistance using these novel com- ponents. Thereby, significantly higher field strengths than the threshold field strength can be used.

Application Advantages • The manufacturing of rotational symmetric and bifurcated components is possible in two productions steps without involving joining processes.

• The wall thickness of rotational sym-metric cups can be strain-adapted.

• Regions which are relevant for further proc- essing steps are no longer subject to strain hardening.

Flow forming technology to produce rotational symmetric and bifurcated components, like belt pulleys or rims

Abstract: The inventive flow splitting method and device allows for the production of rotational symmetric and bifurcated components in an integral action without additional joining processes. Importantly, the compo- nent might be treated in further production steps in a process-sure manner.
