NHY
Our custom CNC machined step pin is a high-performance positioning and transmission component engineered for accurate alignment and anti-slip fixation in industrial fixtures, mold assemblies, and automation equipment. Featuring a precision step shoulder for clear positioning stops and a star-shaped tooth tip for enhanced friction and torque transmission, it is produced via advanced CNC turning, star tip forming, and precision grinding processes to achieve ultra-tight dimensional tolerances. Crafted from wear-resistant carbon steel or stainless steel, this step pin delivers reliable stability and anti-slip performance, resisting deformation and abrasion under long-term dynamic loads and frequent assembly cycles. Fully customizable in pin diameter, step dimensions, star tip specifications, and length, it caters to diverse precision positioning and transmission needs across automation, mold, electronic, and medical industries, ensuring consistent assembly accuracy and efficient power transmission.

3.Application Case
A factory automation client integrated our step pins into precision fixture jigs, using the star tip to lock movable sensor probes in place. The step shoulder ensured accurate positioning, while the star tip eliminated probe slippage during high-speed testing, improving testing accuracy by 29% and reducing setup time by 22%.
A mold manufacturer utilized our alloy steel step pins in plastic injection molds, transmitting torque to movable core components via the star tip. The wear-resistant material withstood 120,000+ mold opening/closing cycles, maintaining positioning accuracy within 0.004mm and reducing mold maintenance downtime by 31%.
Precision Step Structure: Clear shoulder stop for accurate component alignment, eliminating positioning errors effectively.
Star-Shaped Tip Design: Increases contact friction and enables torque transmission, preventing slippage under load and vibration.
CNC Precision Machining: Tight dimensional tolerance (≤0.005mm) ensures consistent fit in precision assemblies.
High Wear Resistance: Hardened steel material extends service life in repeated industrial operation cycles.
Full Customization: Non-standard step dimensions, star tip shapes, and materials are fully customizable to meet diverse needs.
