Method of molding polymeric skins for trim products

摘要

A polymeric skin can be molded by heating a mold surface to a temperature sufficient to melt a casting material and controllably projecting particles of the casting material toward the heated mold surface. Particles of the casting material that impinge on the mold surface melt and adhere to the mold surface. The mold surface is cooled to a temperature at which the casting material solidifies to form a skin. By varying the amount or type of material projected toward the heated mold surface, the method can make multilayer skins, skins from more than one material with a graded transition between materials, multicolor skins, and skim having a controlled, nonuniform thickness.
