Abstract
Casting parameters in at least one of a feeding and mold-filling and squeezing phase are controlled during a casting step in a cold-chamber die-casting machine. The casting parameters are controllable as a function of travel of a casting piston longitudinally displaceable in a shot sleeve. The quantity of molten metal filled in within the shot sleeve is determined by precise metering using a stationary optical measuring device. The metering is accomplished by beaming a measuring beam through a filling port of the shot sleeve and reflecting the measuring beam on a surface of the molten metal. The transit time of the measuring beam and the reflected beam are measured to determine a filling level and quantity of molten metal filled in. A control system is provided which controls a movement of the casting piston and a start of each phase as a function of the filling level and the associated quantity of molten metal filled in.
