Electrical Contact Manufacturers & Custom Solutions

Automatic die rolling is a cold-forming process where wire is shaped between dies without cutting or heating the material. Unlike machining, it generates zero scrap, causes no tool dulling, and produces consistent parts at much higher speeds — up to 5 pins per second — with a defect rate of just 1 in 600,000,000.

Yes. Because Electropin uses lead-free materials such as lead-free brass and stainless steel, their pins fully eliminate REACH and RoHS compliance concerns without requiring leaded brass — a key advantage over traditional machined connector pins that often rely on leaded alloys.

Electropin's custom contact pins serve a wide range of industries including automotive connectors, medical device connectors, farm equipment electrical connections, computer and electronics connectors, and PCB circuit board applications. Pins are available for through-hole mounting, press-fit into metal, and post-insertion into molded plastic.

Electropin offers four primary retention features: Star, Tabs/Spline, Inscribed Square, and Flat. The star feature can achieve a diameter up to 50% greater than the original wire, providing exceptional anti-rotation and high retention strength for demanding connector and PCB applications.

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

Yes. Electropin provides full Design for Manufacturing (DFM) consultation services with experienced engineers, including custom pin design refinement, collaborative engineering for optimal manufacturability, and technical support for performance requirements — ensuring each pin is designed for both function and cost-effective production.
