ABSTRACT:
A method for molding a wire insert in the body of a plastic article to reinforce a bolt-receiving opening. The wire insert is formed of a wire coil in which each convolution of the coil is in contact with its neighboring convolution. The coil has openings between adjacent convolutions to permit liquid plastic to flow between the convolutions as the article is being molded so that the coil is embedded within the plastic.
