ABSTRACT:
An apparatus for finishing or restoring the surface of a plastic article. A receiving chamber receives the article and conveys the article to a finishing chamber. The surface of the article is exposed to a control led concentration of solvent vapor for a period of time in the finishing chamber. The solvent vapor is absorbed into the surface of the article and reforms the surface of the article to a smooth finish. The solvent evaporates off of the surface of the article leaving a smooth glass like finish. A refrigeration system condenser and evaporator are provided to respectively vaporize the solvent in a heating zone, and condense the vaporized solvent in a cooling zone.
