Manufacturing method of integrated foam-molded product and integrated foam-molded product |
摘要 |
To obtain an integrated foam-molded product whose manufacturing cost is reduced and which makes an effective use of a property of an integration target (10). Foaming heat generated at the time of the foaming of a polyurethane foam raw material, whose influence has been conventionally prevented by contriving a special measure, is positively used. The integration target (10) is influenced by foaming heat generated at the time of the foaming of the polyurethane foam raw material in a mold (40), to thermally deform into a desired shape along a mold shape. Consequently, it is possible to mold the integration target into an arbitrary shape in a step of integrating the integration target (10) with a polyurethane foam layer (30) in the mold (40) by integrated foaming, and therefore, there is no need to work the integration target (10) to a state closer to a final shape in a step before it is disposed in the mold (40), which can simplify manufacturing steps and reduce manufacturing cost. |
