Headed Products, also referred to as Cold Forming and Cold Heading, is a high speed and efficient process to make standard and specialty fasteners and specialized components. This process is performed using a cold heading machine that cuts a length of wire from a coil of material, transfers that material into a die and punch cavity, or series of die and punch cavities, to form a cold headed blank that will become a fastener or specialized component after threading and any other operations, like heat treating and/or plating. Almost all standard fasteners in the world are made on cold heading machines.
Here is an example of a part that was successfully converted from a machined part to a Headed Product. The average lot size for this part was about 10,000 pieces.
The machined part started as a slug cut from a bar that was as large in diameter as the largest diameter on the finished part. The slug weight was 3 pounds. Machine time was excessive.
The Headed Product started as a coil of wire, the diameter suited to cold head the part efficiently. The cutoff blank weight was 0.4 pounds, a savings of 2.6 pounds per part. Headed product was produced at 50 parts per minute.
