Automotive PCB Connector Pins | Cold-Formed Precision | Manufacturer

Yes. Because Electropin uses lead-free brass and stainless steel, all pins are fully REACH and RoHS compliant. Unlike machined parts that often require leaded brass for machinability, the cold-forming process works with lead-free materials, eliminating regulatory risk for automotive, medical, and electronics customers.

Electropin's automatic die rolling process achieves a defect rate of just 1 in 600,000,000 pins. This level of consistency is maintained from the very first part to the millionth, making these pins suitable for high-reliability applications in automotive, medical, and electronics industries.

Cold-forming uses automatic die rolling to shape pins from wire stock without cutting or heating the material. This produces zero scrap, eliminates tool dulling, and maintains dimensional consistency from the first pin to the millionth. Machined pins generate cutting waste, rely on leaded brass for machinability, and require periodic retooling that introduces variability over a production run.

Electropin offers four 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, providing strong anti-pull and anti-rotation performance. Retention feature selection depends on the mounting method — press-fit into metal, through-hole PCB, or post-insertion into plastic.

Electropin's pins support three primary mounting methods: press-fit into metal, through-hole PCB mounting, and post-insertion into molded plastic parts. Hinge pins and grooved pins also support high-speed automation applications where pins are oriented and fed down tracks without manual positioning, enabling efficient assembly line integration.

When raw materials are available, Electropin can begin manufacturing and deliver a first batch in as little as two weeks. Subsequent batches are scheduled on a customer-specified timeline, and production can be scaled to accommodate both prototype quantities and high-volume production runs.

Electropin was founded in 1943 and brings over 80 years of cold-forming expertise to every connector pin project. The company offers three generations of manufacturing innovation and provides Design for Manufacturability (DFM) consultation to help customers optimize their custom connector pin designs from the outset.
