ABSTRACT:
A die casting shot sleeve having an overflow hole and an overflow valve for selectively opening and closing the overflow hole. The overflow hole extends through the shot sleeve at a level below the pour hole to allow molten material in excess of a predetermined volume to spill from the shot sleeve. When open, the overflow hole permits excess metal to spill from the shot sleeve. When closed, the metal can be expelled from the sleeve without additional material spilling through the overflow hole.
