Cold Forging is a cold working process where the material is squeezed into a die and the finished parts assume the shape of the die. This process is also known as Cold Heading.

Bar stock or wire stock is fed into a die and is squeezed into the closed die. The resultant part is a nail, a bolt or a screw with the head. A subsequent cold heading operation forms other features on the head such as knurls or slots for screw drivers etc. the shaping rod stock by forming the head as in rivets, bolts, nails and other fasteners. This process can be highly automated and parts can be made economically.
