Bigelow Components Corporation Demonstrates that Cold Heading Custom Components Saves Companies Time and Money

Share Article

Bigelow Components Corporation, a leading manufacturer of cold-headed and stamped custom components for more than 50 years, offers cold heading as an alternative process to machining for small precision metal parts, such as electronic components, contacts, contact rivets, electrodes and miniature components.

According to Bigelow Components Corporation President, Brett Harman, “Recently we were able to save a large automotive company time and money by introducing them to the cold heading process to produce valve tips that were needed for engine exhaust valves. They never thought to use this process because they were stamping 4140 steel, a material that’s generally not cold-heading friendly.”

The cold-heading process applies force to a metal blank with a punch and die. This process can produce a number of head shapes, including square, rectangular, octagonal, conical, diamond, and free form. It is a viable alternative to machining custom parts with faster set-up times and substantially less down time to process a job. In addition, tooling is less expensive and there is no waste, making the process far more cost efficient.

Harman explains, “With this particular customer, the round wire used in the cold heading process offered a more beneficial grain structure, which increased the tips’ strength and ability to withstand greater wear. Stamping these components lead to an inferior part that wasn’t symmetrical, so they needed to be oriented, which made assembly more difficult, time consuming and expensive. Cold heading the valve tips solved this problem and provided our customer with a superior component that was less expensive – simply because of a change in process from stamping to cold heading.”
