Cold Heading of a Brass Split Terminal Pin for the Electronic Connector Industry

C&L Rivet was contracted by a manufacturer of electronic connectors to design a precision cold heading process for this brass rivet. This part was originally produced in a screw machined process, converting the part to cold heading resulted in considerable cost savings. Custom tooling was designed and fabricated in order to complete the switch. The part was completed on our 2 die 3 blow cold header, starting with Ø 0.1180" diameter CDA 260 brass round wire. Finished length was 0.8540", holding tight tolerances of ± 0.002". We employed a tumble deburring process to completely clean and smooth the rivet slot before packaging. We ship 3 million units per year for this customer, with scheduled monthly releases, and turnarounds of 6-8 weeks.

This rivet was previously manufactured in China as a machined part with drilled holes and a machined slot, costing $0.09 - $0.12 per unit. The new cold headed process resulted in a $0.03 per unit cost, an impressive savings. In addition, the new process resulted in increased production speeds and zero material waste. These are typical benefits of converting to cold heading.
