Abstract

Consequently, the resin molding can be coated over the whole surface with a coating material uniformly and with an excellent adhesion. A molding material is compressed and molded with a mold comprising split molds and capable of forming a space between them outer periphery and slidable position of which are tapered, the molds are mutually separated before complete curing to define a space between at least one side surface of the molding and an opposing surface of the mold, a gas flow is formed inside the molds and in a direction towards the outer periphery for discharging any foreign material such as molding-flash and dust through the space to the exterior of the molds, and a fluid coating material is injected in the space between the molding and the surface of the mold and, with the molds clamped again, compressed to be cured.
