To provide a die-casting machine provided with a molten-metal supply device which can melt the necessary quantity of metallic material for each casting and supply molten metal at each time of casting in a casting equipment for continuous casting.

The die-casting machine is provided with a die clamping device 100, which holds a pair of dies 101, 102 and performs opening and closing and clamping of dies 101, 102, an injection device 200 which injects and fills molten metallic material into a cavity C formed by clamped dies 101, 102, and a molten- metal supply device 2 which injects molten-metal into an inlet of a sleeve 206 of the injection device 200. The molten-metal supply device 2 is provided with the material supply system 51 which supplies the necessary quantity of metallic material for each casting at each time of casting, and the melting system 11 which is arranged just above the sleeve 206, melts metallic material supplied at each time of casting by induction heating under high temperature atmosphere and inert gas atmosphere, and injects molten metallic material into the inlet of the sleeve of the injection device.
