ABSTRACT:
According to the present invention, between the mold-clamping process S1in which the mold1is closed and the injection-pressure increase (solidifying) process S3, the gate-melting process for heating the hot runner21to melt the plug (metallic material) of the gate27, the mold-lubricant coating process for spraying the lubricant onto the wall surface of the cavity10, and the material-metering process are simultaneously carried out in parallel to each other. Thus, the molding cycle time can be reduced to a great extent.
