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:
- Phased Ejection
- Primary stage: Short-stroke movement breaks initial part adhesion
- Secondary stage: Full ejection completes part release without distortion
- Modular Construction
- Outer sleeve (main pin) + inner core (sub-pin)
- Integrated spring/gas cushioning prevents impact damage
- Performance Advantages
- 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.
