IPC: B29C41/18
Filed: 1986-06-06
Abstract: PURPOSE:To reproduce embossment or a pattern of a mold faithfully along with simplification of a process by molding the skin layer and a foamed layer at a time, by a method wherein a foamable resin layer is formed on the surface of a mold and the unfoamed skin layer is left on the mold side by expanding the foamable resin layer selectively. CONSTITUTION:A mold 2 is loaded with foamable resin 2 foaming through heating. Then the mold is heated at the temperature which is sufficient for fusing foamable resin powder and the same is set to a powder box in which the foamable resin powder is put. After the set mold and the powder box have been inverted and the foamable resin powder has been fused and stuck to the mold by suspending the same for a predetermined period of time, the surplus foamable resin powder is discharged by inverting the set mold and powder box again. Then the mold 1 is heated uniformly from the backside, that is, a resin 2 side by a heating unit 3. Foaming of unfoamed foamable resin 2 is started by this heating from the surface remote from a mold surface, that is, the surface close to the heating unit 3. Although the foaming is kept advancing toward the mold surface in order, the foaming is stopped by stopping the heating by leaving a thickness necessary for the skin layer.
