Precision Electrical Connector Pins | Cold-Formed | Supplier

Electropin uses Automatic Die Rolling, a cold-forming process that shapes metal wire without cutting or heating the material. This eliminates scrap, prevents tool dulling, and enables production of up to 5 pins per second. The process ensures dimensional consistency from the first pin to the millionth with a defect rate of just 1 in 600,000,000.

Electropin's connector pins are available in lead-free brass, stainless steel, and other metals. All lead-free material options eliminate REACH and RoHS compliance concerns, making them suitable for regulated industries such as automotive, medical devices, and consumer electronics without requiring leaded brass as used in traditional machined parts.

Yes. Because Electropin uses lead-free raw materials in its cold-forming process, all pins fully eliminate REACH and RoHS regulatory concerns. Unlike machined parts that often require leaded brass for machinability, Electropin's die rolling process works with compliant materials without sacrificing accuracy, speed, or retention strength.

Electropin offers four retention feature options: Star, Tabs/Spline, Inscribed Square, and Flat. The star feature can increase pin diameter by up to 50% compared to the base wire diameter, providing high retention and anti-rotation strength in press-fit metal, through-hole PCB, and post-insertion plastic molded applications.

Electropin supplies precision connector pins to the automotive, farm equipment, medical device, computer and electronics, and circuit board manufacturing industries. Their pins support a wide range of mounting methods including through-hole PCB mounting, press-fit into metal, and post-insertion into molded plastic parts across all these sectors.

When raw materials are available, Electropin can begin manufacturing and deliver a first batch of custom cold-formed pins in as little as two weeks. Subsequent production batches are delivered on customer-specified timelines, and production volume can be scaled dramatically to accommodate changing demand without compromising quality or turnaround.
