Process Details

How Cold Heading Works

You use cold heading to shape metal wire into small parts. This process happens at room temperature. You do not need to heat the metal. Cold heading uses a multi-station machine. The metal blank moves through each station. Each station forms the metal a little more. You can make screws, bolts, and nuts with cold heading. The process works fast and produces many parts in a short time.

• Cold heading is a high-speed process.

• The metal blank moves through several stations in the machine.

• You use cold heading to make small and medium-sized hardware items.

You start with a wire or rod. The machine cuts the wire to the right length. The first station forms the head of the part. Later stations shape the rest of the part. You get strong and accurate parts with cold heading. You do not waste much material. You can make thousands of parts every hour. Cold heading gives you smooth surfaces and tight sizes.

How Cold Forging Works

You use cold forging to shape metal at room temperature. Cold forging works for many types of parts. You can make gears, shafts, and other mechanical items. The process uses strong machines.
