Abstract
A method for molding plastic caps onto preformed metallic shanks, the metallic shanks having a head portion and a leg portion, wherein the leg portion of the shanks are inserted into a carrier member leaving a portion of the head portion elevated from the carrier member. A molding device is thereafter engaged with the carrier member over the head of the shank to form a molding cavity therearound. Plastic is then injected into the mold cavity to surround and encapsulate the head portion. The mold cavity is thereafter open and the completed capped shank is removed from the carrier member. The carrier member can comprise an elongated strip which can be pulled through work stations performing the various forming, inserting and injecting steps in regulated fashion.
