Abstract
A stroke-end position of an injection cylinder of the die cast machine is detected and a position of the injection cylinder for sending a boosting-signal is set. This position is a predetermined standard boost stroke distance from the stroke-end position. When the injection cylinder reaches the position for sending the boosting-signal in the casting cycle, an oil-pressure intensifier is advanced. In this method, before casting is performed, a value representing a stroke after slowing-down and a setting value of the plunger stopping position are determined and the start point for slowing-down is calculated by subtracting the value of the stroke after slowing down from the setting value.
