SMD Header Pins | Cold-Formed Precision | Manufacturer

Electropin's automatic die rolling process achieves an industry-leading defect rate of just 1 in 600,000,000 pins. Unlike machined parts where tool wear degrades accuracy over time, cold-forming dies do not dull, ensuring consistent dimensional precision from the very first pin produced to the millionth and beyond.

Electropin's SMD header pins support three primary mounting methods: press-fit into metal, through-hole PCB mounting, and post-insertion into molded plastic parts. Several pin types, including grooved and hinge pins, are also optimized for high-speed automation assembly lines where pins slide down tracks without requiring individual orientation.

Retention feature options include Star, Tabs/Spline, Inscribed Square, and Flat profiles. The star feature can expand pin diameter up to 50% beyond the base wire diameter, providing exceptional pull-out resistance. Tabs and spline designs offer strong anti-rotational performance, making them suitable for PCB and molded plastic applications with tight tolerances.

Electropin can begin manufacturing custom cold-formed pins and deliver the first batch in as little as two weeks, provided raw materials are available. Subsequent production runs are delivered on a customer-specified timeline. Production volume can also be scaled dramatically when demand increases, without requiring significant retooling or lead time extensions.

Electropin supplies custom connector pins to the automotive, agricultural/farm equipment, computer and electronics, and medical device industries. Pins are used in connector housings, circuit board assemblies, molded plastic components, and press-fit metal applications across all these sectors, from under-hood automotive connectors to precision medical device interfaces.

Yes. Electropin provides Design for Manufacturing (DFM) consultation at no charge as part of its engineering collaboration process. Customers work directly with Electropin's team — led by owner Keith Brenton, who has over 35 years of experience — to refine pin geometry, select retention features, and optimize designs for high-speed cold-form production before any tooling is committed.
