发明名称 PRODUCTION OF PATTERNED PLASTIC MOLDED ARTICLE
摘要 PURPOSE:To produce an injection molded article having a transferred pattern layer and free of cracks or wrinkles by a method wherein a transfer sheet is perfectly closely contacted to the inside surface of a receiving mold by an elastic body, and after heat-forming the sheet, a molten resin is injected into the mold. CONSTITUTION:The transfer sheet 3 consisting of a base sheet 1 and a transfer layer 2 is placed on the receiving mold 5 with the transfer layer 2 directed upward, then the transfer sheet 3 is pressed by the elastic body 6 (rubber, sponge or the like) and is heated to perfectly closely contact the sheet 3 to the inside surface of the mold 5. Therefore, the elastic body 6 is removed, an injection mold 7 is clamped onto the receiving mold 5 and the molten resin 8 is injected into the mold. After the resin is solidified, the mold is opened and the patterned plastic molded article 9 having the transfer layer 2 is separated from the base film 1. The heating of the transfer sheet 3 is carried out by heating the elestic body 6 or the receiving mold 5, or by directly heating the sheet 3. Accoringly, generation of cracks or wrinkles is prevented.
