Abstract

The invention is for a method to produce components from a blank made of deep-drawable material using a free-flowing action medium. The method consists in clamping the blank in a forming device in which the action medium applies a pressure to the blank, preforming the blank be elevating the pressure exercised by the action medium in restricted areas of the blank and finish forming the preformed blank with a forming tool.
