OK, so just what is “Cold Heading” anyway?

Cold Headed Bolts

Cold heading is a process that starts with metal wire (often steel, aluminum, copper, nickel, or a precious metal, such as gold, silver or platinum) that is formed into a blank.  Then, a high-speed automated cold header applies force to the blank with a punch and a die.  When the force applied by the die exceeds the metal blank’s yield strength, the material gives and takes on the shape of the die.  All this is done without the addition of heat; hence the “cold” heading.

The process is so effective, first, because it allows a supplier to make many extremely precise parts (up to 400 a minute) in innumerable different shapes, including custom designs.  Second, the cold forming process strengthens the metal through deformation.  This makes cold headed parts far more durable and resistant to shock and fatigue than small metal parts created through other processes.  Third, no scrap metal is produced because the metal is shaped, rather than cut or otherwise removed.  All these elements lead to speed, efficiency, and low costs, always appreciated by the customer!
