Cold heading is an advanced manufacturing process where a length of wire is cut from a coil then placed into a die. A hammer will then either upset the material (i.e. place a head on it) or extrude the material (i.e. force the wire into a smaller cavity within the die).
Through cold headed manufacturing, working material is simply rearranged, as opposed to other production methods that require material to be cut, ground or cast into shape.
Therefore, there is no loss of material in cold heading, and typically no scrap, making it an extremely efficient, cost-effective and environmentally-friendly production method.
