Precision Progressive Die Stamped Connector Pins

These cylindrical metal components typically serve as male pins or contacts in electrical connector systems, ensuring stable electrical conductivity between PCBs, wire harnesses, and terminals. The sidewalls feature longitudinal slots or cutouts that provide radial elasticity, generating appropriate normal force when mated with female sockets. This design maintains low contact resistance and prevents signal transmission interruptions.

The manufacturing process utilizes high-speed progressive die continuous stamping to gradually form strip metal into tubular structures. Key controls focus on outer diameter consistency, slot gap precision, and overall straightness. To address springback and deformation issues common in thin-walled tube forming, production relies on high-precision molds and high-speed presses with 0.005mm accuracy. Optical image measurement instruments are used for 100% inspection of micro-features to guarantee dimensional stability in batch deliveries.

The factory holds dual IATF 16949 and ISO 9000 certifications. We support processing of conductive and elastic materials such as brass, phosphor bronze, and stainless steel, and offer surface treatments including gold, silver, nickel, and tin plating to meet corrosion resistance and low impedance requirements. Quotations are evaluated based on specific 3D drawings, material grades, plating specifications, and expected order volumes, catering to precision connection needs in communications equipment, automotive electronics, and industrial control sectors.
