Title: METHOD OF PRIMARY FORMING A MATERIAL
Abstract:
The invention relates to a method according to which a metal (13) is re-shaped by a primary forming process. The aim of the invention is to improve such a method so that heat can be relatively easily added to the part and so that the addition can be varied as regards space and time. To this end, a voltage is applied to parts of the primary forming device between which the metal is disposed during the insertion process and/or during the primary forming process and/or during a subsequent treatment in the primary form after the primary forming process so that a closed circuit is produced and heat energy is supplied to the metal by the closed circuit.
