摘要:
A method of injection-molding a thermoplastic resin, which involves the steps of(a) injecting a molten resin of a thermoplastic resin into a cavity provided in a mold composed of a fixed mold member and a movable mold member,(b) introducing a predetermined amount of a coating material into between the resin in the cavity and the cavity wall after the injection of the molten resin is completed, to allow the resin in the cavity to be compressed with the introduced coating material and/or to allow the movable mold member to move in the mold-opening direction, and(c) maintaining a molding pressure before the mold releasing at a level higher than 0 kgf/cm.sup.2.
