Super easy-to-use Two-Stage Ejector Pin

Specifications：SKH61

The two-stage ejector pin is a specialized ejection mechanism in injection molds featuring a telescopic dual-segment design for smoother, more controlled part release. It's particularly effective for deep-cavity or complex geometries.

Key Features:

1. Phased Ejection

• Primary stage: Short-stroke movement breaks initial part adhesion
• Secondary stage: Full ejection completes part release without distortion

• Outer sleeve (main pin) + inner core (sub-pin)
• Integrated spring/gas cushioning prevents impact damage

• Eliminates ejection marks (stress whitening) on finished parts
• Ideal for thin-wall components (e.g., caps, electronic housings)
• Reduces wear and seizure risks in high-cycle production

Material Specification:
 tungsten steel with TiN coating for enhanced abrasion resistance.

This system optimizes ejection force distribution through sequential motion, significantly improving reliability in precision molding applications while extending mold service life.
