发明名称 METHOD FOR MOLDING POLYESTER RESIN TWO-COLOR PATTERN MOLDED ARTICLE
摘要 PROBLEM TO BE SOLVED: To mold a pattern molded article from a combination of a polyester resin BMC molding material and a separate polyester resin compound material by a mold (b) in such a state that both materials are bonded without generating peeling between the materials. SOLUTION: The polyester resin material is charged in the mold of which the molding temperature is set so as to provide a temperature difference between a cavity mold and a core mold, and the mold is closed to mold the molded article in which an uncured part is generated on the side set to a low temperature among the cavity mold and the core mold and the mold is opened while leaving the molded article in the mold. Subsequently, the separate colored polyester resin compound material is charged in the mold set to the low temperature and the mold is again closed to perform molding to mold a two-color molded article wherein both materials are compounded and bonded chemically.
