Custom Hollow Contact Pins for Sale | Manufacturer

Electropin offers four primary retention feature options: Star, Tabs/Spline, Inscribed Square, and Flat. The Star feature can achieve a diameter up to 50% greater than the wire raw material, making it ideal for high-retention press-fit and post-insertion applications requiring strong anti-rotational holding force.

Electropin's custom hollow contact pins support three primary mounting methods: press-fit into metal parts, through-hole PCB mounting, and post-insertion into molded plastic parts. Many pin types also support high-speed automation applications where pins travel down tracks without requiring orientation.

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 delivered on a customer-specified timeline, and volume can be scaled up rapidly when demand changes.

Yes. Electropin's cold-forming process produces lead-free pins that fully comply with both REACH and RoHS regulations. Unlike machined pins that typically require leaded brass to prevent tool wear, Electropin's die rolling process requires no cutting — eliminating the need for lead entirely and removing compliance concerns.

Electropin serves automotive, farm equipment, computer and electronics, and medical device industries, as well as circuit board manufacturers and molded plastic parts producers. Their pins are used in connector assemblies, PCB through-hole mounting, press-fit metal applications, and high-speed automated assembly lines.

Automatic die rolling cold-forms pins without cutting, which means no scrap material, no tool dulling, and no need for retooling across long runs. This results in a defect rate of just 1 in 600,000,000 pins, production speeds of up to 5 pins per second, and lower per-unit cost compared to machined alternatives.
