Abstract (en)
[origin: EP0576795A1] The invention proposes a method and an apparatus for carrying out the method intended for process control of a die casting machine comprising a casting set (2) and a casting drive (1). In order to control the movements of both the press plunger or driving piston (8) in the press cylinder (7) and the multiplying piston (17) in the multiplying device (15) in all phases of the casting process, stepless displacement/speed-measuring devices (30, 31) are provided to determine the position or movements, and rapidly controllable servo proportional valves (33) to (36) are provided to control the movements both of the press plunger (8) and of the multiplying piston (17). <IMAGE>
