Abstract
PURPOSE: A part material for marking is fitted to the depression which is provided in the cavity of the mold so that the part material can be fixed and, after the mold is clamped, a resin is injected vertically to the back surface of the part material, thereby conducting injection molding with holding the part material in place.
CONSTITUTION: Mark 1 previously formed from synthetic resin, rubber or other material is fitted to the depression with the shape of the mark in cavity 6. After the mold is clamped, the molding material is injected from nozzle of an injection machine through runner 8 and pressed through gate 2 into cavity 6 vertically to the back surface of mark 1. The molding material further expands radially to fill all of the cavity. Thus, molding is completed.
