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. ທີ່mouldparts.net, we manufacture shoulder ejector pins to exacting standards, using premium materials and advanced heat treatment for unmatched performance in high-stress molding environments.

Reinforced Shoulder Design
Providesenhanced stabilityduring ejection, reducing deflection and wear.
Prevents lateral movement, ensuring precise alignment in complex molds.
High Wear Resistance
Made fromSKD-61 (JIS) ຫຼືH13 (DIN) tool steel, hardened to50-54 HRC.
OptionalSKH-51 (High-Speed Steel) for extreme abrasion resistance (up to62-64 HRC).
Customizable Dimensions
Standard diameters: 2mm–25mm (custom sizes available).
Shoulder height and diameter tailored to your mold design.
Surface Treatments
Nitriding, TiN coating, ຫຼືDLC coatingfor reduced friction and extended service life.
