ABSTRACT:
Pressing-in devices of pressure die casting machines operate as hydraulically driven multiphase as pressing-in systems in order to exercise a different pressure on the casting material during different phases of the casting operation. The casting piston of a pressing-in device is driven by at least one electric motor. In this case, the drive advantageously takes place using a multispeed servomotor which interacts with a multiple-roll spindle.
