METHOD FOR PRODUCING MOLDING AND PLUG FOR THE METHOD

摘要

PROBLEM TO BE SOLVED: To control the thickness spots of an obtained molding to a degree not to deteriorate the appearance of the molding, and manufacture a molding excellent in mechanical strength. SOLUTION: When a synthetic resin sheet is spread along the inner surface of the cavity 8 of a mold 6 and molded by evacuating the cavity 8 from its inner surface, the molding of the sheet 14 is assisted by pushing the sheet 14 in the mold 6 direction by using a plug 16 having a press part 162 in which a recessed part extending substantially in the direction X to be inserted into the cavity 8 from the opposite cavity side surface of the sheet 14 is on a peripheral wall.
