ABSTRACT:
Into the cavity formed by closing a stationary mold with a movable mold, material is filled through a gate portion of a female cutter. After the material is filled into the cavity, a male cutter is advanced at a high speed from a starting position S to a vicinity position P of the female cutter, at the position P the advance speed is changed to a low speed and the male cutter advances at the low speed to an advancing limit position E to carry out the gate cutting. Then, the filled material solidifies while being cooled.
