摘要:
A method of making a composite foamed and shaped article including in the first step in which a thermoplastic resin powder is filled in a slush molding die to form a first resin layer, a second step in which a mixed powder consisting of a heat decomposable foaming agent and the thermoplastic resin powder is filled in the die in which the first resin layer was already formed, to form a second resin layer on the surface of the first resin layer, and a third step in which the heat decomposable foaming agent is made to foam by heat treatment to form a final product of a composite foamed and shaped article wherein the slush molding die is pre-heated by an infrared heating method.
