Patent abstract
In the press hardening process when a blank is formed and cooled in cooled tools (30,31), the tools are used as a fixture during the hardening. The tools have alternately contact surfaces (33,34) and clearances (35) in a certain area against the formed product (20-24) and the contact surfaces have an area that is less than 20% of the area. As a result, this area will be a soft zone (11) of the final product and the zone will have good dimensional accuracy.
