ABSTRACT:
A method of manufacturing an uncoated covering for an automotive instrument panel. The method comprises the steps of providing an electroplated nickel tool having a grained surface. A quantity of melt fusible powered vinyl is dispensed within the tool. The tool is heated to melt the vinyl and to form the covering. The vinyl leaves deposits on the tool surface. The vinyl covering is cooled and removed from the tool. The tool is periodically cleaned with an aqueous solution of 14% by weight glycol ether DPM and 4% by weight triethanolamine to remove the unwanted deposits before they can mar the finish on the vinyl covering.
