Abstract

PURPOSE:To provide an injection-molded article easy to adhere strongly, has excellent mechanical properties, and is laminated rigidly, by a method wherein a polyamide copolymer film is sandwiched between mold parting surfaces, and a homopolymeric polyamide is injection molded. CONSTITUTION:A copolymerized polyamide film 6 is sandwiched between parting surfaces 8 of molds 1, and a homopolymeric polyamide 9 is injected from a sprue 2 into a cavity 4 through a gate 4 to be molded. Thus, the copolymerized polyamide film 6 is laminated on the surface of the injection-molded homopolymerized polyamide 9 with a strong adhesive force.
