A method for delivering molten metal to a shot sleeve of a casting machine from a molten metal furnace. A molten metal pump is positioned within the furnace. The pump includes a molten metal outlet in fluid communication with the shot sleeve. A shaft and impeller or screw assembly of the pump is selectively rotated to introduce molten metal to the shot sleeve in a predetermined quantity. The predetermined quantity is determined by a controller that receives a signal from a trigger mechanism associated with the molten metal outlet.

Provided are a die casting method and a die casting apparatus for preventing molten metal from being unexpectedly supplied into a sleeve under decompression. Molten metal supply control for pumping up molten metal with an electromagnetic pump and supplying the molten metal into a sleeve in a state of decompressing a cavity of a die and the inside of the sleeve attached to the die, including: moving the surface of the molten metal, with the electromagnetic pump, from a standard position to the side opposite to a supply direction of the molten metal; decompressing the cavity and the inside of the sleeve; and weakening force of the electromagnetic pump, which pumps down the molten metal to the side opposite to the supply direction to supply the molten metal into the sleeve.
