Small Connector Pins | High-Speed Cold-Form Precision | Manufacturer

Electropin's automatic die rolling process achieves an industry-leading defect rate of just 1 in 600,000,000 pins. Because the cold-form tooling does not generate heat or experience dulling, dimensional accuracy remains consistent from the very first pin to the millionth, ensuring no quality degradation across long production runs.

Electropin's high-speed automatic die rolling technology produces up to 5 custom connector pins per second. This production rate, combined with dramatically scalable manufacturing capacity, means Electropin can quickly respond to changing volume requirements while maintaining consistent quality and lead times.

Yes. Because Electropin uses lead-free brass and stainless steel, all connector pins are fully REACH and RoHS compliant without requiring special exemptions. Unlike machined parts that often require leaded brass to prevent tool wear, Electropin's cold-forming process works efficiently with lead-free materials, eliminating compliance concerns entirely.

Electropin offers four retention feature types: Star (which can achieve up to 50% greater diameter than the wire raw material for maximum hold), Tabs/Spline (for anti-rotation and high retention strength), Inscribed Square (for secure seating), and Flat (for standard applications). Multiple mounting methods are supported including press-fit into metal, through-hole PCB mounting, and post-insertion into plastic.

Electropin's cold-formed connector pins serve a broad range of industries including automotive connectors, medical devices, PCB and circuit board assembly, computer and electronics manufacturing, and farm equipment electrical systems. Both solid contact and mechanical pin types are suitable for post-insertion into molded plastic parts and press-fit into metal components.

When raw materials are available, Electropin can begin manufacturing your custom connector pins and deliver the first batch in as little as two weeks. Subsequent batches are delivered on a customer-specified timeline. Electropin also provides Design for Manufacturing (DFM) consultation to help finalize specifications before production begins, minimizing delays.
