Contact Pins | Scrap-Free Cold-Form Production | Manufacturer

Electropin produces contact pins in lead-free brass and stainless steel as standard material options, with other metals available for specific applications. Lead-free brass offers excellent electrical conductivity and formability, while stainless steel provides superior hardness and corrosion resistance. Lead-free materials ensure full REACH and RoHS compliance without requiring leaded alloys.

Electropin offers four primary retention features: Star, Tabs/Spline, Inscribed Square, and Flat. The star feature can achieve a diameter approximately 50% greater than the wire raw material diameter, providing high pull-out force and anti-rotation performance. Each feature is formed in-process with no secondary operations required.

Electropin's pins support three primary mounting methods: press-fit into metal parts, through-hole PCB mounting, and post-insertion into molded plastic parts. The retention feature geometry is selected based on the mounting method and the required pull-out force and anti-rotation performance for the specific application.

Yes. All Electropin contact pins are manufactured from lead-free materials, which eliminates the primary substance-of-concern that triggers REACH and RoHS compliance limits in connector pins. Unlike machined parts, cold-formed pins do not require leaded brass to achieve machinability, so compliance is inherent to the manufacturing process rather than a secondary plating step.

Electropin's cold-formed contact pins serve the automotive, farm equipment, computer and electronics, medical device, and circuit board assembly industries. Applications range from high-reliability automotive connector systems and medical device connectors to PCB through-hole assemblies and high-speed automation insertion processes across all these sectors.

Electropin can begin manufacturing custom contact pins in as little as two weeks from design approval when raw materials are available. Subsequent batches are delivered on a customer-specified timeline, and production volume can be scaled dramatically to accommodate changes in demand without retooling or quality degradation.
