The movement of molten metal in die casting can be distinguished into the following two steps, i.e., (1) influx of molten metal through the gate, and (2) movement of injected metal in the cavity of die. As for the first, we studied the movement of plunger and the pressure thereon by application of proper apparatus and measurement with an oscilograph. As for the second, we observed the movement of radioactive lubricant, through which we could judge the movement of molten metal. The following is the report on the first step movement. Under constant injection speed, the injection pressure was the highest in Zn alloys and the lowest in Mg alloys. The coefficient of effluence slightly differed among the three alloys. In this experiment, also the distinctive features of Mg alloy die casting were exploved by observation of the movement of these three kinds of alloys.
