Pin Shaft
Pin Shafts for Automotive and Industrial Assemblies
Pin shafts are precision metal components used for positioning, pivoting, alignment and mechanical connection. Their dimensions and geometry determine how they fit into mating parts and function within an assembly.
Wuyuan Jieyi Automotive Electrical Appliance Co., Ltd. manufactures pins, shafts, stepped shafts and custom cold-forged components for automotive, electrical appliance and industrial applications. We develop components according to engineering drawings, specified dimensions and application requirements.

Core Advantages
Cold Forging for Efficient Component Production
Cold forging forms metal under pressure, making it suitable for producing specific pin and shaft geometries with reduced material waste compared with machining parts entirely from solid stock. The process is selected according to component design and material characteristics.
Geometry Matched to Assembly Requirements
Straight shafts, stepped profiles, shoulder dimensions and end configurations serve different positioning and connection functions. Manufacturing specifications are established around the drawing dimensions and critical interfaces required for assembly.
Automated Manufacturing Processes
Jieyi's production resources include cold-forging machines, thread-rolling equipment and automated production lines. These capabilities support the manufacture of formed metal components, with secondary operations determined by individual product requirements.
