Abstract
A method of forming a carpeted plastic part includes positioning a carpet between first and second mold halves, wherein the carpet has a back surface. A non-reinforced plastic strip is positioned adjacent a portion of the back surface of the carpet. A hollow parison of reinforced plastic material is formed between the first and second mold halves. The first and second mold halves are then closed together to form a carpeted plastic part having a thinned-down region of the reinforced plastic material adjacent the plastic strip such that the plastic strip is sandwiched between the thinned-down region and the carpet to form a flexible living hinge.
