Electropin achieves a defect rate of just 1 in 600,000,000 pins. This sub-parts-per-billion defect rate is made possible by the automatic die rolling cold-forming process, which delivers consistent dimensional accuracy across every production run, from the first pin to the millionth.

Yes. Electropin offers lead-free connector contacts manufactured without leaded brass, which fully eliminates REACH and ROHS compliance concerns. Unlike machined parts that require leaded brass for machinability, cold-formed pins can be produced from compliant materials including lead-free brass and stainless steel without sacrificing performance or dimensional accuracy.

Electropin manufactures connector contacts from lead-free brass, stainless steel, and other metals depending on application requirements. Lead-free brass offers excellent electrical conductivity and formability, while stainless steel provides greater hardness and corrosion resistance — both available without REACH or ROHS compliance concerns.

Electropin can begin manufacturing and deliver a first batch of cold-formed connector pins in as little as two weeks when raw materials are available. Subsequent production batches are delivered on a customer-specified timeline, and production volume can be scaled up rapidly at speeds of up to 5 pins per second to meet changing demand requirements.

Electropin offers a broad range of connector pin designs, including press-fit pins, grooved pins, barbed pins, hinge pins, PCB through-hole pins, solid contact pins, and fully custom connector pins. Each pin type is cold-formed using automatic die rolling for zero-scrap production and industry-leading dimensional consistency.

Electropin offers four retention feature options: Star, Tabs/Spline, Inscribed Square, and Flat. The Star feature is particularly notable, capable of expanding pin diameter up to 50% greater than the original wire diameter — providing strong anti-rotation and high pull-out retention strength for press-fit and post-insertion applications.

Yes. Electropin provides Design for Manufacturing (DFM) consultation, custom pin design refinement, and a collaborative engineering process to optimize your connector contact specifications for cold-forming production. Custom die molds are created for specific pin geometries, and technical support is available throughout the design and production process. An Electropin engineer will respond to quote requests with pricing, lead time, and DFM recommendations within one business day.
