ABSTRACT:
A vacuum die-casting machine has a bellows forming a sealed enclosure between the rear of the fill chamber and the piston rod. A vacuum is applied to the enclosure during evacuation of the die cavity and charging of the fill chamber with molten metal. As the piston moves forward, an inert gas at about atmospheric pressure is introduced into the enclosure and extends into the feed tube.
