High-Precision Shoulder Ejector Pins for Injection Molds | Durable & Customizable Solutions
CATEGORY AND TAGS:Ejector Pin enquiry
- Specifications
Shoulder ejector pins are 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. AtMouldParts.net, we manufacture shoulder ejector pins to exacting standards, using premium materials and advanced heat treatment for unmatched performance in high-stress molding environments.
Key Features & Benefits
Reinforced Shoulder Design
- Providesenhanced stability during ejection, reducing deflection and wear.
- Prevents lateral movement, ensuring precise alignment in complex molds.
High Wear Resistance
- Made fromSKD-61 (JIS) orH13 (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, orDLC coating for reduced friction and extended service life.
Global Compliance
- MeetsISO 9001 andRoHS standards. Compatible with automotive, medical, and consumer electronics molds.
