Cold Heading/Forging
Process Description
Coiled wire is straightened as it is fed into high speed, horizontal, forming machines. Wire is then formed into part's shape through a series of dies and upsets. Various diameters and shoulders can be formed utilizing this process. Threads (if applicable) are formed using high-speed thread rolling machines that squeezes the unthreaded "blank" between two dies. The blank is stretched during this process displacing material to form a thread that is larger in diameter than the "blank."
