Connector Pins Manufacturer in Wisconsin

Electropin manufactures connector pins from lead-free brass and stainless steel. Lead-free brass offers excellent electrical conductivity and formability, while stainless steel provides superior corrosion resistance and mechanical strength. Both materials eliminate REACH and RoHS compliance concerns without requiring leaded brass, unlike traditional machined alternatives.

Electropin produces a comprehensive range of connector pin types including custom connector pins, die-rolled pins, press-fit pins, barbed pins, grooved pins, knurled pins, hinge pins, PCB connector pins, solid electrical contact pins, dowel pins, gauge stop pins, and cold-formed solid pins — all manufactured via automatic die rolling cold-forming technology.

Electropin offers four primary retention feature types: Star, Tabs (Spline), Inscribed Square, and Flat. The star feature can achieve approximately 50% greater diameter than the raw wire material, making it ideal for high-retention press-fit and anti-rotation applications in PCBs, molded plastic parts, and metal components.

When raw materials are available, Electropin can begin manufacturing and deliver the first batch of cold-formed pins in as little as two weeks. Subsequent production batches are scheduled on a customer-specified timeline, and production volume can be scaled dramatically to meet changing demand without lengthy retooling delays.

Yes. Because Electropin uses lead-free brass and stainless steel — and cold-forming rather than machining — no leaded brass is required at any stage of production. This means all lead-free pins are fully REACH and RoHS compliant, eliminating regulatory hurdles for customers in the EU and other regulated markets.

Electropin serves a broad range of industries including automotive connector assemblies, farm equipment electrical systems, computer and consumer electronics, medical device connectors, and PCB/circuit board manufacturing. Pins are used in through-hole PCB mounting, press-fit into metal, and post-insertion into molded plastic part applications across all these sectors.
