Blade Ejector Pin
Product Introduction: High-Quality Blade Ejector Pins
In injection molds and die-casting molds, Blade Ejector Pins are specialized ejection components designed for thin-wall products, deep rib products, and applications where round ejector pin marks are not permitted. Their thin and flat cross-sectional design provides sufficient ejection force in space-constrained areas while minimizing interference with product structures. As a mold manufacturer that produces for our own use, we maintain extremely stringent standards for cross-sectional precision, wear resistance, and anti-rotation design of blade ejector pins. Every pin undergoes precision machining and rigorous inspection to ensure no deformation, no sticking, and no rotation during long-term ejection cycles.
✅ Self-Produced and Self-Used, Rigorously Selected
We are not only a supplier of mold components but also a mold producer ourselves. Through extensive practical experience in our own molds, we have repeatedly validated the steel selection, heat treatment process, cross-sectional dimensional accuracy, and surface finish of blade ejector pins. Only those with sufficient rigidity, excellent wear resistance, and exceptional durability are approved for our supply system.
✅ Premium Materials, Strong and Wear-Resistant
Our blade ejector pins are manufactured from high-quality hot work mold steels such as SKD61 or SKH51, undergoing quenching, tempering, and nitriding treatment to achieve a working surface hardness of HV900-HV1100. Excellent red hardness and wear resistance ensure dimensional stability under high-temperature, high-frequency ejection conditions, with no head deformation or wear.
✅ Precision Machining, Accurate Cross-Section
The thin and flat cross-section of each blade ejector pin is precision ground, with width and thickness tolerances strictly controlled within 0/-0.01mm to 0/-0.02mm. The transition area features a radius design to reduce stress concentration and prevent breakage. Surface roughness is maintained below Ra0.4μm, ensuring smooth, stick-free ejection.
✅ D-Shaped Head Design, Reliable Anti-Rotation
The blade ejector pin head features a standard D-shaped anti-rotation design that precisely mates with the corresponding D-shaped hole in the mold core, effectively preventing pin rotation during operation. This ensures the thin and flat cross-section consistently maintains proper orientation, preventing ejection failure or mold damage caused by rotational movement.
✅ Wide Application Range, Solving Thin-Wall Ejection Challenges
Blade ejector pins are particularly suitable for the following difficult ejection applications:
Thin-Wall Products: Mobile phone cases, battery boxes, thin-wall containers
Deep Rib Products: Reinforcing ribs, snap-fits, rib plates in narrow spaces
Appearance Parts: Product surfaces where round ejector pin marks are unacceptable
Gear and Rack Products: Applications requiring avoidance of tooth structure interference
✅ Complete Specifications, Customized Solutions
For standard specifications, we maintain regular inventory of common cross-sectional widths ranging from 1.0mm to 12.0mm, various thicknesses, and lengths for quick dispatch. For non-standard customization, based on your mold structure and product requirements, we offer custom blade ejector pins with special cross-sectional dimensions, special lengths, special head shapes, and multi-step configurations.
✅ Strict Quality Control, Stable Performance
Every blade ejector pin undergoes hardness testing, dimensional inspection, and surface flaw detection before shipment, ensuring no cracks, no annealing soft spots, and no machining defects. We guarantee that our blade ejector pins will not break, stick, or rotate under normal operating conditions.
