Abstract
The present invention relates to a process for producing a skin material-laminated foamed thermoplastic resin molding and to foamed thermoplastic resin moldings, said process comprising a skin material and a thermoplastic resin foam integrally laminated with the skin material, wherein the process uses a mold comprising a male and female mold members which are mutually slidable and whose cavity clearance (t) is adjustable, the process comprising the following steps (1)-(5): (1) skin material supply step, (2) resin injection step, (3) compression step, (4) foaming step and (5) cooling and releasing step, and said moldings that are a panel-shaped foamed thermoplastic resin molding comprising a substrate and a projection standing on the substrate wherein the projection has a mean expansion ratio of not greater than 1.1 times and the substrate has a mean expansion ratio of not less than 1.3 times.
