The innovation for complex components made of press hardened steel
The blanks are heated to roughly 900 °C. This is followed by an innovative non-contact pre-cooling process that uses air to cool below 550 °C in an effort to prevent microcracks. During the subsequent forming process, the blanks are brought to their final geometry and hardened. Tailored-property parts can also be manufactured from laser-welded blanks.
