Air Poppet Valves

AJV Air Poppet Valve

The AJV Air Poppet Valve is a precision core component for plastic injection molds. Adopting air-assisted demolding design, it effectively eliminates vacuum adhesion and product sticking issues that commonly occur with thin-wall, deep-cavity and easily deformed plastic parts. Replacing rigid pin ejection, it enables soft, uniform air ejection to achieve stable automatic part dropping and improve molding smoothness.

Key Material & Precision Specifications

- Premium Material: Adopts high-grade SUS420 stainless steel, featuring high hardness, wear resistance, corrosion resistance and long service life.

- Heat Treatment Hardness: HRC 48–52, maintaining stable mechanical performance under high-frequency mold opening and closing cycles.

- Working Pressure: 1.5–6 Bar, perfectly compatible with standard mold air supply systems.

- Precision Machining: CNC machined with tight tolerance and smooth finish, ensuring flexible reset and reliable airtight sealing.

- Universal Standard: Conforms to AJV, CUMSA, HASCO and DME international mold standards with high interchangeability.

Core Features & Advantages

- Anti-sticking Demolding: Breaks vacuum adsorption between parts and mold cavities, solving sticking problems of deep-cavity and enclosed plastic products.

- Flawless Molding: Air-blow demolding avoids ejection marks, white spots and deformation, ensuring high-quality product surfaces.

- High-cycle Stability: Features stable reset performance and excellent elasticity, suitable for long-term automated mass production.

- Easy Operation: Compact integrated structure, simple installation and replacement without complex debugging.

- High Efficiency: Supports automatic part falling, reduces manual operation and optimizes mold production cycle.

- Leak-proof Sealing: Precise poppet sealing structure prevents air leakage during mold closing and ensures stable air output during ejection.

Application Scope

Ideal for precision injection molds, this air poppet valve is widely used for thin-wall, flat, deep-cavity, transparent, cosmetic and medical plastic parts with high surface requirements. It serves multiple industries including electronics, auto parts, medical devices, packaging and daily consumer goods.

Product Characteristics Summary

The AJV Air Poppet Valve is a high-performance essential mold component for precision and efficient injection molding. It compensates for the shortcomings of traditional ejection structures, protects mold cavities, stabilizes product quality, lowers defective rates and mold maintenance costs.
