ABSTRACT:
A method of fabricating a needle useful in the dispensing of plastic fasteners and a needle fabricated by the method. In a preferred embodiment, the method involves electroplating a nickel alloy onto a master, the master being made of a meltable material and being appropriately shaped to produce an unfinished shank portion of a needle. The master is then melted away from the electroplated metal, leaving behind an unfinished shank portion. The unfinished shank portion is then finished by machining, and a plastic base portion is insert-molded around the end thereof.
