Abstract
A method of manufacturing a cover layer for a vehicle interior component includes forming a mold cavity via a first surface and a second surface spaced apart from one another by a distance. The first surface is configured to form a show surface of the cover layer, the second surface is configured to form a rear surface of the cover layer, and the distance is less than or equal to 1 mm. The method of manufacturing the cover layer also includes heating the first surface and/or the second surface, and flowing liquid polyvinyl chloride into the mold cavity to form the cover layer.
