Abstract: A process for producing metal bodies, in particular for the production of stators for use in electric motors, has a plurality of steps. Firstly, a stack of a plurality of sheet metal parts is introduced into a cavity of a tool, with thermally curing adhesive layers being provided between the sheet metal parts. The stack is then heated to effect curing of the adhesive layers, forming the metal body. During heating, a pressure is applied to the stack. At least one of the following parameters is measured during the process: applied pressure, temperature of the stack, height of the stack. A prescribed height of the stack is set by use of a temperature-pressure control. The BPS™, BPS-Backpaketiersystem™ or Backpaketiersystem™ according to the invention makes efficient and precise production of stators possible, is self-learning and allows measurement, regulation and recording of all production parameters during production of each single stator.
