Electrical Pins | Cold-Formed Precision Manufacturing | Supplier

A circuit pin is a precision-formed metal component used to establish electrical connections on printed circuit boards (PCBs). These pins are inserted into PCB holes using through-hole or press-fit mounting methods, securing them within the board to carry electrical signals between components. They are typically manufactured from conductive materials such as brass or stainless steel.

In electronics, a pin refers to a small precision-formed metal contact that conducts electrical current between components in a connector, PCB, or assembly. Electrical pins are manufactured from conductive materials such as brass or stainless steel and feature retention geometries — such as stars, splines, or barbs — to secure them within plastic or metal housings while maintaining a stable electrical connection.

Electropin's product range includes PCB connector pins, press-fit pins, barbed pins, grooved pins, knurled pins, hinge pins, dowel pins, gauge stop pins, die-rolled pins, and solid contact pins. All pin types are produced in lead-free brass or stainless steel and are available across multiple mounting methods including through-hole PCB mounting, press-fit into metal, and post-insertion into plastic.

Electropin uses a proprietary Automatic Die Rolling cold-forming process that shapes wire material into finished pins without cutting or heating. This eliminates scrap, prevents tool dulling, and enables production of up to five custom connector pins per second. The result is a defect rate of just 1 in 600,000,000 pins with consistent, identical quality from part 1 to part 1,000,000.

Yes. Electropin manufactures all pins in lead-free brass or stainless steel, which eliminates the need for leaded brass entirely. This means all lead-related REACH and RoHS thresholds are not a concern, simplifying compliance documentation for customers in regulated industries such as automotive and medical devices.

Electropin offers four retention feature options: Star, Tabs/Spline, Inscribed Square, and Flat. The Star feature can expand the pin diameter up to 50% greater than the wire raw material diameter, providing strong press-fit retention. These features enable anti-rotation and high pull-out strength for both plastic and metal assemblies.

Electropin can begin manufacturing and deliver a first batch of custom cold-formed pins in as little as two weeks when raw materials are available. Subsequent production batches are scheduled on a customer-specified timeline, and production volumes can be scaled to accommodate changing demand. To get started, submit your specifications and an Electropin engineer will respond with DFM guidance and pricing typically within one business day.
