A die casting machine has a clamping device and an injection device. The clamping device has a fixed die plate which holds a fixed die, a movable die plate which holds a moving die, an electrically operated die opening and closing-use driving device which moves the movable die plate in a die opening and closing direction, and a clamping cylinder which generates a clamping force. The injection device has a sleeve, a plunger which capable of sliding in the sleeve, an electrically operated injection-use driving device which drives the plunger at least at the time of low speed injection, and an injection cylinder which drives the plunger at least at the time of high speed injection.
