Industrial Automation Connector Pins | Cold-Formed Precision | Manufacturer

Electropin offers four primary retention features: Star, Tabs/Spline, Inscribed Square, and Flat. These features provide anti-rotation and high pull-out strength for press-fit into metal, through-hole PCB mounting, and post-insertion into molded plastic applications. The star feature can expand pin diameter to approximately 50% greater than the original wire diameter.

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 scheduled on a customer-specified timeline, and production volumes can be scaled dramatically when demand increases or project needs change.

Yes. Because Electropin's cold-forming process does not require leaded brass — unlike traditional machined parts — all lead-free brass and stainless steel pins are inherently REACH and RoHS compliant. This eliminates regulatory documentation burdens and simplifies compliance for automotive, medical, and electronics applications sold into regulated markets.

Electropin's pins support three primary mounting methods: press-fit into metal, through-hole PCB mounting, and post-insertion into molded plastic parts. Multiple pin types — including press-fit, grooved, barbed, solid, and PCB connector pins — are engineered to meet the specific retention and installation requirements of each mounting method.

Electropin serves the automotive, farm equipment, medical device, computer and electronics, and PCB assembly industries. Cold-formed pins are used in connector housings, circuit board assemblies, molded plastic components, and metal subassemblies across each of these sectors. Custom designs are available to meet unique performance or dimensional requirements in any of these applications.

Unlike machining, automatic die rolling cold-forms pins by shaping wire stock without cutting or heating the material. This eliminates scrap entirely, prevents tool dulling, and maintains consistent tolerances from the first pin to the millionth. The result is a defect rate of 1 in 600,000,000, faster production of up to 5 pins per second, and lower per-unit cost compared to machined alternatives.
