Buy Automotive Circular Connector Pins in Bulk | Manufacturer

Electropin's automatic die rolling process is optimized for bulk production, producing up to 5 pins per second. Contact their team for project-specific MOQ guidance. Because there is zero scrap and no retooling required, high-volume orders are cost-efficient from the start.

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

Yes. Electropin's cold-forming process uses lead-free brass and stainless steel, meaning no leaded materials are required — unlike traditional machined parts. This eliminates REACH and RoHS compliance concerns entirely, simplifying regulatory documentation for automotive and medical supply chains.

Electropin offers four retention feature options: Star (which can expand diameter up to 50% greater than the wire diameter), Tabs/Spline, Inscribed Square, and Flat. These provide anti-rotation functionality and high retention strength for press-fit, through-hole PCB, and post-insertion plastic mounting applications.

Electropin uses lead-free brass, stainless steel, and other metals suited to the application. Material selection depends on the required electrical conductivity, hardness, and compliance requirements. Both soft materials like brass and hard materials like stainless steel are supported by the automatic die rolling process.

Yes. Electropin offers a full Design for Manufacturing (DFM) consultation, custom pin design refinement, and collaborative engineering to develop pins to your exact specifications. Custom die molds are created for specific designs, and technical support is available throughout the process to optimize performance and manufacturability.
