A method for injection molding a metallic material is disclosed in which an injecting material comprised of a half-solidified metallic material and a molten metallic material is injected into a cavity of a die from an injection cylinder through a gate thereof. A non-product portion remaining at the gate of the die is separated from a product portion while it is still hot. The separated high-temperature non-product portion is press-formed into a billet in the injection cylinder. Utilization of heat from the injecting material in melting the high-temperature billet enables reuse of the non-product portion remained at the gate and reduction of heat energy required in melting the billet.
