The cold heading process is one of the new pressure machining processes for metal with little or no cutting. It is a processing method that uses the plastic deformation of the metal under the action of external force, and with the help of the mold, the metal volume is redistributed and transferred, so as to form the required parts or blanks. The cold heading process is most suitable for the production of bolts, screws, nuts, rivets, pins and other standard fasteners.
