摘要： An object is to provide a thermoplastic resin molded article concurrently having excellent heat insulating properties, rigidity, and lightness, and to provide a method for producing the same. A molded article made from a thermoplastic molding material comprises: a multilayer structure portion having a surface layer composed of a non-foamed type of said molding material and an internal layer composed of a foamed type of said molding material; and a portion composed of only a non-foamed type of said molding material. The molded article is produced by injecting and filling an expandable thermoplastic molding material which is melted in the heating cylinder that is adjusted to have the temperature of its tip part higher than that of its rear part, into a cavity having a 10 to 95% volume of the volume of the molded article, conducting a first cooling until the molding material becomes the condition that the surface layer contacted with the metal mold is solidified but the internal layer is melted, enlarging the volume of the cavity to the volume of the molded article to foam at least a part of the internal layer, and conducting a second cooling to take out the molded article.

摘要： The present invention provides a thermoplastic resin structure which has a three-layer structure of flexible skin layer/flexible foamed material layer/hard substrate layer wherein each of the layers comprises a thermoplastic resin capable of melt-adhesion with each other, and the flexible foamed material layer is formed by the injection foam molding method. The resin structure exhibits the capability of being easily recycled and, at the same time, can be produced at a low cost, which has not been achieved by a conventional structure using a cross-linked foamed sheet or a urethane foam, while maintaining the performance in appearance, cushioning, rigidity and the like, and thus markedly useful for application fields requiring high performance in cushioning, sound absorption, heat insulation and the like in automobiles, household electrical appliances, general industrial parts and the like.
