摘要： Method of and apparatus for die casting metal in which the die parts have a well for receiving the molten metal in a body preliminary to closing the die parts and gating channels lead from the well to the mold chambers. One of the die parts has means for injecting a pre-metered volume of water into the body of metal in the well so that after the die parts are closed together and the injecting means are operated to inject the water the rapid conversion of the water into steam and subsequent expansion produce sufficient force to cause the molten metal in the well to be forced into the mold chambers where it is chilled thereby forming the castings.
