Abstract
A method of forming a molded plastic article with a second surface with molded extensions, and a first surface that is substantially free of sink mark defects. The method involves forming, from a first plastic material, a first molded section with at least one molded extension extending from the second surface. The molded extension is formed in a mold recess with a reversibly positionable slide. After formation of the first molded section, the slide is retracted to a second slide position thus forming within the molded extension a retainer cavity that is in fluid communication with an aperture in the first surface of the first molded section. A second plastic material is introduced into the mold over the first molded section, and a portion thereof passes through the aperture and into the retainer cavity, thereby forming a second molded section that is continuous with each retainer. The first and second molded sections, which together form the molded article, are fixedly attached to each other by at least one molded retainer, and the first surface of the second molded section, which defines the first surface of the molded article (), is substantially free of sink mark defects. The present invention also relates to a molded article.
