Cold heading machine is a machine in the manufacture of a stamping machine, the original material without any changes, mainly softening or hardening and other similar treatment, the material into the shape of the required shape, in general, are shaped as " Steps ".
Cold forging method can be used to manufacture fasteners, connecting pieces (such as bolts, nuts, screws, rivets, etc.) with the steel can also be called cold heading steel, commonly known as riveting screw steel. Commonly used are quenched and tempered alloy steel, low temperature tempering superalloy structural steel, low carbon low alloy high strength steel, ferrite-martensitic duplex steel. Cold heading is made of metal at room temperature. The use of cold heading process manufacturing fasteners, not only high efficiency, good quality, and the use of materials, low cost. But the cold heading process requires a higher quality of raw materials.
