A die casting machine includes a clamping device which opens and closes and clamps a pair of die halves, an injection apparatus which performs injection to the pair of die halves by making a plunger move forward in a sleeve communicated with a space between the pair of die halves, and a control device which controls the clamping device and injection apparatus. The control device includes an injection control part and press-use clamping control part. The injection control part controls the injection apparatus so as to start the injection in a state where the pair of die halves face each other through a gap. The press-use clamping control part controls the clamping device so that the die contact and clamping are carried out after the start of injection. Further, the injection control part performs control for decelerating the plunger before the plunger stops.
