Abstract:
A method for producing a laminated molding comprising a thermoplastic resin base and an ether type urethane foam provided on at least one side of the base, the ether type urethane foam mainly made of polyether polyol, wherein, when the urethane foam is set onto one of the molding surfaces of mutually opposing dies and a thermoplastic resin is supplied to the dies to integrally attach the thermoplastic resin base with the urethane foam simultaneously with injection compression molding or injection molding, a pressure loading applied to the resin is retained at not more than 50 kg/cm2 of average pressure relative to a project area of a molding cavity, and wherein the resin is filled while keeping a cavity clearance between the mutually opposing dies not less than a thickness of the urethane foam and not more than a value adding 20 mm to the thickness.
