Shoulder ejector pinsare critical components in injection molds, designed to ensure smooth and reliable ejection of molded parts. Featuring a reinforced shoulder structure, these pins deliver superior strength, alignment, and longevity compared to standard ejector pins. AMouldparts.net, we manufacture shoulder ejector pins to exacting standards, using premium materials and advanced heat treatment for unmatched performance in high-stress molding environments.
Característiques clau & Avantatges
Reinforced Shoulder Design
Providesenhanced stabilityduring ejection, reducing deflection and wear.
Prevents lateral movement, ensuring precise alignment in complex molds.
