Mold Air Ejectors
Product Introduction: High-Quality Mold Air Ejectors
In injection molds and blow molds, the Air Ejector is a critical auxiliary component for demolding, particularly suitable for deep-cavity products, products with high vacuum adhesion, or products requiring ejector pin mark-free surfaces. As a mold manufacturer that produces for our own use, we maintain extremely stringent standards for sealing performance, response speed, and installation convenience of air ejectors. Every air ejector undergoes precision machining and rigorous testing to ensure no air leakage, no sticking, and rapid response during long-term production.
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 material selection, sealing structure, spring life, and installation method of air ejectors. Only those with reliable sealing, sensitive response, and exceptional durability are approved for our supply system.
Premium Materials, Precision Machining
Our air ejectors are manufactured from SUS304 stainless steel or high-quality SKD61 mold steel, offering excellent corrosion resistance and wear resistance. The mating surfaces of the valve core and body undergo precision grinding, with fit clearance controlled to micron levels, ensuring flexible operation and reliable sealing even in high-temperature and high-pressure environments.
Working Principle, Assisting Demolding
The air ejector is controlled by an external air source. During the ejection stage, it injects compressed air between the product and mold to break the vacuum adhesion state, assisting smooth product demolding. Particularly suitable for:
Deep-cavity products (such as buckets, boxes)
Large-area thin-wall products
Appearance parts requiring ejector pin mark-free surfaces
Transparent parts with high vacuum adhesion
Multiple Structures, Strong Adaptability
We offer various structural types of air ejectors to meet different mold requirements:
Standard Air Ejector: Built-in return spring, ejects when air is applied, automatically returns when air is cut off, simple structure, easy installation
Guided Air Ejector: Added guide structure, suitable for side blowing or special angle installation
Miniature Air Ejector: Compact size, suitable for space-constrained mold structures
Adjustable Flow Type: Built-in throttle valve for adjustable blowing flow and speed
Multiple Seals, No Leakage
Air ejectors feature high-quality O-rings or special sealing structures, resistant to high temperature, oil, and corrosion, ensuring no leakage during long-term high-pressure operation. Seals are made of fluororubber or silicone rubber, adaptable to high-temperature environments exceeding 200℃.
Easy Installation, Simple Maintenance
Air ejectors adopt standard thread mounting (such as M6, M8, M10, etc.). Simply machine the mounting hole in the corresponding mold position and screw in. Air connections use standard quick-fit couplings for easy connection to external air sources. Replacement or maintenance is convenient without affecting other mold components.
Complete Specifications, Customized Solutions
For standard specifications, we maintain regular inventory of common thread sizes and strokes for quick dispatch. For non-standard customization, based on your mold space and product requirements, we offer custom air ejectors with special thread sizes, special strokes, special mounting methods, and multi-channel air circuit integration.
We Can Also Source for You
