BGS Series Square Interlocks - Precision Straight Block Positioning Sets

Product Overview

CUMSA standard air valves are functional mold components designed to support air-assisted ejection and improve part release in plastic injection molds.
Manufactured according to CUMSA standard specifications or strictly based on customer drawings, these air valves provide controlled air flow, stable response, and reliable performance in multi-cavity, high-cycle injection molding applications for packaging and medical products.

Key Features & Technical Advantages

• Manufactured to CUMSA standard or built-to-print requirements

• Precision air valve design for air-assisted demolding

• Improves part release and reduces sticking or deformation

• Stable performance in multi-cavity injection molds

• Suitable for high-cycle and continuous molding operations

• Compatible with automated injection molding systems

Applications & Industries

CUMSA standard air valves are widely used in plastic injection molds for:

• Bottle caps and closures

• Packaging containers and thin-wall plastic components

• Medical disposable products and syringe-related parts

• Injection molds requiring air-assisted ejection or venting

Typical customers include packaging manufacturers, cap and closure producers, medical consumable factories, and OEM injection mold makers.

Mold Structure & Design Description

The air valve is installed within the mold cavity or core area to introduce compressed air at controlled timing during mold opening or ejection.
Its internal valve structure allows precise air release, helping separate molded parts from cavity surfaces without mechanical stress.
Design considerations include air channel positioning, sealing reliability, response sensitivity, and compatibility with multi-cavity mold layouts.

Manufacturing & CNC Machining Capability

All air valves are manufactured in-house using precision CNC machining and controlled finishing processes.

Manufacturing capabilities include:

• Precision CNC turning and milling of air valve components

• Machining of internal air passages with tight tolerance control

• Precision grinding for sealing and functional surfaces

• Stable and repeatable machining processes for mold standard parts

In-house inspection equipment is applied throughout production to ensure dimensional accuracy and functional reliability.
