Buy Crimp Contact Pins in Bulk | Manufacturer

Electropin manufactures crimp contact pins from lead-free brass, stainless steel, and other metals. All material options are available in lead-free formulations, which eliminates REACH and RoHS compliance concerns — an important advantage over conventional machined pins that often require leaded brass to achieve machinability.

Yes. Because Electropin uses cold-forming rather than machining, lead-free materials are fully workable, meaning no leaded brass is required. This makes all pins inherently REACH and RoHS compliant without special processing, simplifying your regulatory documentation for automotive, medical, and electronics applications.

Electropin offers four retention feature options: Star, Tabs/Spline, Inscribed Square, and Flat. The star feature can expand the pin diameter up to 50% beyond the wire raw material diameter. These features provide anti-rotation locking and high pull-out retention strength for press-fit, through-hole PCB, and post-insertion plastic applications.

Electropin can begin manufacturing and deliver a first batch of cold-formed pins in as little as two weeks when raw materials are available. Subsequent batches are delivered on a customer-specified timeline, and production capacity can be scaled up significantly when volume requirements change on short notice.

Electropin's pins are engineered for three primary mounting methods: press-fit into metal, through-hole PCB mounting, and post-insertion into molded plastic parts. Select product lines also support high-speed automation applications where pins slide down tracks without needing specific orientation during assembly.

Automatic die rolling is a cold-forming process that shapes pins without cutting or heat, so tools never dull and material grain structure is preserved. This results in a defect rate of just 1 in 600,000,000 pins and zero in-process scrap. Machined pins suffer from tool wear, burring, and cutting waste that increase cost and reduce consistency over long production runs.
