Abstract
A method and apparatus for molding a plastic cap on a preformed metallic shank includes inserting the shank on a strip material by a shank insertion device such that a head of the shank is elevated above the strip material. A molding device, having an open mold cavity is engaged with the strip material such that the strip material acts as a portion of the mold. The elevated head is positioned within the cavity. Plastic is injected into the mold cavity to surround and encapsulate the button head.
