Square Ejector Pins
Core Product Features
The square ejector pins are solid rod-type precision components precisely machined by CNC lathes. They serve as core basic parts for mechanical transmission, fixture positioning, and mold ejection. Dimensional tolerances for outer diameter and length are strictly controlled, with excellent coaxiality and cylindricity, ensuring accurate pushing and positioning without deviation. The square ejector pins can be processed into smooth rods, stepped, threaded, flat, slotted, and irregular structures, offering strong customization flexibility.
