APPARATUS AND METHOD FOR MOLDING ON CARRIER STRIP MATERIAL

摘要

A method and apparatus for molding a plastic cap (120) on a preformed metallic shanked member (62) includes inserting the shanked member (62) in a strip material (24) by a shank insertion device (60) such that the head (66) of the shanked member (62) is elevated above the strip material (24). A molding device (110), having an open mold cavity (116) is engaged with the strip material (24) such that the strip material (24) acts as a portion of the mold. The elevated head (66) is positioned within the mold cavity (116). Plastic is injected into the mold cavity (116) to surround and encapsulate the head (66).
