ABSTRACT:
The subject matter of the present invention is a method of shaping a metallic hollow member in a shaping tool (1, 20, 50) at increased temperature and under internal pressure, said hollow member (5) protruding at one end at least from said shaping tool (1), the configuration of the tool mold and/or the shaping parameters acting onto said hollow member being selected in such a manner that said hollow member (5, 59) substantially keeps its original shape outside said tool (1, 20, 50), with said tool being heated in the region of the cavity and a tool, said tool being completely made from a homogeneous ceramic material with the component part being heated inductively, the cavity having a tribological additional coating in order to minimize friction of the component part against the wall and/or the affinity of the component part with the material of the cavity wall.
