Abstract

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.
