  • How It Works – Cold Forming makes fasteners and a lot

    Though there was a U.S. patent issued in 1794 for a 'cold header' (really a rivet machine), cold forming became a practical fabrication technology after World War II. The typical one-die, two-punch method is common in producing headed parts, especially fasteners. The first blow combines partial head upset (coning) with shank extrusion.
