    摘要： Spherical particles having a diameter between 0.007" and 0.040" are formed from melt extruded thermoplastic material suitable for casting on a heated mold surface and melting thereon to form a thin layer of material having a nominal thickness of 0.040" that is cooled and removed from the mold surface as a part having a porosity less than a visually observable threshold. The process includes the steps of providing microspheres formed of blended and melt extruded thermoplastic, plasticizers (if necessary) and pigment additives that constitute less than 5% by weight of the blend and shaped as a smooth round spherical particle. The microspheres may then be distributed as predetermined charge of such microspheres against the heated casting surface to melt the microspheres as a layer of thermoplastic material having a porosity less than 0.003 inches and thereafter cooling and removing the non-porous layer from the casting surface.

    摘要： A method of producing a molded foam article having an integral skin and a backing layer of foam comprising mixing particles of two polyvinyl compounds one of the compounds having a molecular weight less than that of the other compound and a higher solvating plasticizer than that of the other compound and casting the mixture against a heated mold surface and melting the one compound to flood the interstices of the particles of the other compound and float to the surface of the heated mold to form a skin and wherein the other compound includes foaming constituents to simultaneously form a layer of foam material behind the skin.
