Abstract

PURPOSE: To manufacture a cabinet and mold itself easily and inexpensively, by performing molding by casting molten synthetic resin through only one point of a film gate communicating with a cavity part which is on the opposite side of the cavity part forming unpresentable surface of a molded article.
CONSTITUTION: A runner 2, gate 3 and cavity 4 communicating with a sprue 1 are formed by a stationary mold 5 and movable mold 6. Further, the runner 2 and its gate 3 are a piece each and that the gate 3 is a film gate. When synthetic resin 11 with which a foaming agent 10 has been mixed is injected under a molten state and the molten resin is cast into the cavity 4 from the center of a cavity part 4a through the sprue 1, runner 2 and gate 3, a front cabinet 7 is molded. As the molten resin is cast through only one point of the gate 3, a weld line 12 becomes only the one point of the center of the cavity part and creases A are hardly generated as the gate 3 is the film gate because the flowability of the molten resin is favorable.
