The damage to devices are avoided, by performing operation control of a hydraulic operating means and an electric servomotor, that are adapted as drive sources in an injection step, separately and not performing coordinate control. A die casting machine 1 includes a tubular injection sleeve 12, an injection plunger 13, an electric servomotor 17 and a hydraulic operating means 21 which are used as a drive source of an injection step, and a control means 30 which controls the electric servomotor 17 and the hydraulic operating means separately, when injecting and filling the cavity of the mold, which has been closed, with the molten metal by the advancing of the injection plunger 13, during a low-speed injection step and a high-speed injection step which is performed at a higher speed than the low-speed injection step, in the injection step.
