Abstract
A die casting system having an inclined shot sleeve. A pour hole is located in the upper end of the inclined sleeve. The size, shape, and position of the pour hole and the inclination of the shot sleeve are selected so that, when the sleeve is filled to capacity, the volume of air remaining in the sleeve equals the volume of material displaced by the plunger as it closes the pour hole. As the plunger is advanced, the air in the shot sleeve is expelled through the pour hole; and preferably the last air is expelled just as the pour hole is closed.
