Cold Heading Process Explained
The cold heading process involves several critical stages:
-
Cutting the Wire: The metal wire is cut to the required length, determined by the specifications of the fastener.
-
Heading: The cut wire is fed into the cold heading machine, where it undergoes the initial shaping through dies.
-
Extrusion and Upsetting: After heading, the piece may undergo further shaping processes, such as extrusion or upsetting, to achieve the desired dimensions.
-
Finishing: The final product is then finished, which can include threading or surface treatment to enhance durability.
Advantages of Cold Heading Machines
