Abstract

A process and an apparatus for producing a molded skin product such as an interior decoration member like an instrument panel for an automobile or other vehicle. The process includes charging a desired amount of synthetic resin powder into a treating container disposed facing a predetermined shaped molding mold surface. The mold surface is heated to a temperature of at least the melting temperature of the synthetic resin. The powder is spattered onto the mold surface by violently agitating the same by an agitation means whereby a fused coating of the powder is formed on the mold surface. The spattering is discontinued when the coating reaches a predetermined thickness. The mold surface is cooled thereby solidifying the coating to form the molded skin material. The molded skin material is then removed from the mold surface. The powder can be fluidized during the spattering. The apparatus includes the treating chamber for receiving a charge of synthetic resin powder, a metallic mold forming with the treating chamber a closed chamber with the mold having a mold surface facing the treating chamber, equipment for selectively heating and cooling the mold surface, and an agitation mechani…
