Abstract
In a die cast machine of the type wherein molten metal in a metal melting furnace is poured into an injection sleeve and the molten metal in the injection sleeve is injected into a die, a ladle having a molten metal discharge port is used to receive the molten metal from the furnace. The lower portion of the ladle is inserted into the injection sleeve. Then the port is opened to discharge the molten metal in the ladle into the injection sleeve and the ladle is continuously raised at such a speed that the level of the molten metal in the sleeve is always maintained at a level near the port.
