摘要： Provided is a method for manufacturing a mold for manufacturing a molded article, by which not only is the occurrence of flash suppressed but also the crystallization of the surface is sufficiently accelerated when the mold temperature during the molding of a crystalline thermoplastic resin is set at Tc2−100° C. or less. Based on a relationship between crystallization rate and resin temperature of the crystalline thermoplastic resin, a temperature at which the crystalline thermoplastic resin filled into a mold has a sufficiently fast crystallization rate near a cavity surface and a retention time during which the crystalline thermoplastic resin in the mold is retained at a temperature equal to at least at a temperature at which the resin has the sufficiently fast crystallization rate are derived, such that the derived temperature and the derived retention time allow the molded article to have a surface whose crystallinity falls within a desired range, and a heat-insulating layer which, when mold temperature is Tc2−100° C. or less, allows a time, during which temperature near surface of the mold cavity is retained at no less than the derived temperature, to fulfill the derived retention time is provided.

摘要： Composite molded articles having relatively rigid and flexible resin regions are bonded to one another along an interfacial fusion zone. A normally solid thermoplastic polyalkylene terephthalate resin preform (which will constitute the relatively rigid region of the composite article) is placed in a mold cavity. The flexible region of the composite article is then formed by introducing a molten thermoplastic polyester elastomer resin into the mold cavity at a temperature which is greater than the melt temperature of the solid preform. The introduced thermoplastic polyester elastomer resin contacts and at least partially plasticizes a surface region of the solid preform along the interfacial bonding zone within the mold cavity to thereby cause the polyester elastomer resin to coalesce with the at least partially plasticized surface region of the polyester resin. Upon cooling and solidification, the solid preform and the polyester elastomer are fused to one another along the interfacial bonding zone.
