Abstract
A method of forming thermoplastic panels is disclosed which includes the steps of forming the thermoplastic panels by extrusion or a similar process and simultaneously or subsequently texturing or graining at least one face thereof, and utilizing such pre-textured or pre-grained panels to form a finished panel or article by disposing such panel in a thermoforming mold having at least one grained or textured mold surface against which the pre-textured or pre-grained surface of the panel is disposed and thermoforming such panel. The process provides a textured or grained surface having greatly improved uniformity and enhanced appearance.
