Lamella Contact Pins | Cold-Formed High-Conductivity | Manufacturer

When raw materials are in stock, Electropin can deliver a first batch of cold-formed pins in as little as two weeks. Production schedules are flexible and can be scaled up significantly to match changing volume requirements, making Electropin suitable for both prototype and high-volume production runs.

Electropin offers four standard retention feature types: Star, Tabs (Spline), Inscribed Square, and Flat. The Star feature is particularly powerful — it can achieve up to 50% greater diameter than the original wire raw material, providing strong press-fit retention in both metal and molded plastic housings.

Yes. Because Electropin's cold-forming process does not require leaded brass (unlike traditional machining), all lead-free pins are fully compliant with both REACH and RoHS regulations. This eliminates the compliance burden that manufacturers typically face when sourcing machined contact pins made with leaded alloys.

Electropin serves the automotive, agricultural equipment, computer and electronics, and medical device industries. Pins are used in connector housings, PCB through-hole mounting, press-fit metal assemblies, and post-insertion into molded plastic components — covering a wide range of electrical and mechanical connection applications.

Cold-forming shapes metal by die rolling wire stock without cutting or heating, producing zero scrap. Machined pins are cut from bar stock, generating significant waste and requiring regular tool sharpening that degrades part consistency. Electropin's automatic die rolling produces up to five pins per second with no tool dulling and near-zero defect rates.

Yes. Electropin offers Design for Manufacturing (DFM) consultation with experienced engineers, including a custom pin design refinement service. Their team will collaborate with you to translate your performance requirements into an optimized pin geometry that is manufacturable at high speed, low cost, and consistent quality.
