Stainless Steel Hinge Pins | Manufacturer

Hinge pins are not universal. They vary in diameter, length, material, and retention feature design to match specific application requirements. For precision industries like automotive connectors, medical devices, or PCBs, custom hinge pins are engineered to exact tolerances. Electropin specializes in designing and manufacturing hinge pins to your exact specifications using cold-forming technology.

Electropin manufactures hinge pins in two primary materials: stainless steel and lead-free brass. Both options are fully lead-free, eliminating REACH and RoHS compliance concerns. Stainless steel is preferred for applications requiring corrosion resistance, while lead-free brass suits high-conductivity connector applications in automotive and electronics industries.

Electropin offers four retention feature options — star, tabs (spline), inscribed square, and flat. These features provide anti-rotation and high pull-out resistance for press-fit and post-insertion applications. The star feature can achieve approximately 50% greater diameter than the source wire raw material, delivering exceptional retention strength in metal and molded plastic assemblies.

Electropin's cold-forming process enables rapid turnaround. The first batch of custom hinge pins can be delivered in as little as two weeks. Subsequent production batches are delivered on a customer-specified timeline, with production speeds of up to five pins per second supporting high-volume orders at scale.

Electropin's hinge pins are used across automotive connectors, farm equipment, medical devices, computer and electronics connectors, and PCB/circuit board assemblies. Their design flexibility — supporting press-fit into metal, post-insertion into plastic, through-hole PCB mounting, and high-speed automation — makes them suitable for demanding applications across these sectors.

Yes. Electropin provides full Design for Manufacturing (DFM) consultation, custom pin design collaboration, and custom die mold creation for unique pin specifications. Their engineering team works directly with customers to refine dimensions, retention features, and material choices, ensuring each hinge pin meets precise performance and assembly requirements.
