Abstract

A composite moulded product having cushioning properties in which a cushioning material having a surface material is integrally provided on a hard base material and a method for producing the composite moulded product in a simple process having less producing steps. A hard resin moulded product is set in a metallic mould, and an expandable rubber-like elastic body is injected, and then the metallic mould is expanded so that expansion of the rubber-like elastic body can be effected, whereby the expanded rubber-like elastic body and the skin layer thereof constitute a cushioning material and a surface material, respectively, and the formation of those materials and integration of those materials with the hard base material as a hard resin moulded product can be performed in succession in one metallic mould. Thus, production is made simple and labor and production cost can be reduced. <IMAGE>
