PURPOSE:To roll the end part of a surface skin to the back side of a base material, fusion-bond it and omit the treatment of the end part, by placing the surface skin of which the end is bent inside on the cavity face of a mold, then filling the space surrounded by the surface skin with foamable resin beads and foaming them. CONSTITUTION:At first, the surface skin 8 of which the end part 8a is bent inside is shaped by covering a sheet 6 on a mold 1, then reducing a pressure by a vacuum pump 3 and also heating it. The surface skin 8 is set on the cavity face 10 of a bottom force 9, then a top force 13 is clamped and the foamable resin beads 21 are filled in the space S surrounded by the surface skin 8 from a pouring pipe 20 and heat foamed, and the molded object 23 in which the surface skin 8 is fusion-bonded without a clearance to the surface of the base material 24 composed of foamed resin beads 21a...is obtained. EFFECT:A manufacturing process is simple and a manufacturing cost is low. |
