Abstract

A tool may be used to shape and/or partially press harden a workpiece. In some examples, the tool may comprise a main body having a surface, as well as a heat conducting system containing a thermal medium. The heat conducting system is integrated in the tool in such a way that, for the heating of the surface, a heat radiating from a heat source is conducted by means of the heat conducting system to the surface of the main body. Further, the heat conducting system may comprise a thermal oil or a melt as the thermal medium. The surface of the main body may be configured to face the workpiece during the shaping or partial press hardening of the workpiece.
