Brass Electrical Pins | Lead-Free Cold-Formed | Manufacturer

Electropin achieves an industry-leading defect rate of just 1 pin per 600,000,000 produced. This exceptional accuracy is made possible by cold-form tooling that does not dull over time, ensuring consistent dimensional precision from the very first pin to the one-millionth pin in a production run.

Yes. Because Electropin's cold-forming process requires no leaded brass, all pins are manufactured lead-free by default, fully eliminating REACH and RoHS compliance concerns. This is a significant advantage over machined pins, which typically require leaded brass to prevent tool wear and galling during cutting.

Electropin's automatic die rolling equipment produces up to 5 custom connector pins per second. Production can be dramatically scaled when demand increases, and the first batch of custom pins can typically be delivered in as little as two weeks from when raw materials are available.

Electropin offers four retention feature options: Star, Tabs/Spline, Inscribed Square, and Flat. The star feature can expand the pin diameter up to 50% beyond the original wire diameter. These features provide anti-rotation and high retention strength for press-fit into metal, through-hole PCB, and post-insertion into plastic applications.

Electropin's pins support three primary mounting methods: press-fit into metal parts, through-hole PCB mounting for circuit board assemblies, and post-insertion into molded plastic parts. Select hinge and grooved pin designs also support high-speed automation applications where pins slide down tracks without requiring orientation.

Yes. Electropin provides a full Design for Manufacturing (DFM) consultation service. Their engineers collaborate with customers to refine pin geometry, select appropriate retention features, and optimize designs for the cold-forming process — helping ensure the final part meets performance requirements while minimizing cost and lead time.
