摘要

Production of a metallic workpiece comprises directly and/or indirectly heating a core (2) to a predetermined temperature to adjust the hollow chamber (3) for the workpiece (4) to be produced and fitting the size of the hollow chamber and pre-tensioning of a reinforcement (6) by further heating and/or cooling the core. An independent claim is also included for a molding tool for producing a metallic workpiece.
