Adhesive Vacuum Defoaming Solution

Working Condition Requirements

• Material Type: Adhesives for consumer electronics (various binders, potting compounds, dispensing glues, etc.)

• Initial State: During production of consumer‑electronics manufacturers, massive micro‑bubbles are mixed into adhesives in stirring processes. Residual bubbles impair adhesive performance and product reliability, which remains a major industry challenge.

• Processing Target: Efficiently remove nano‑scale micro‑bubbles from adhesives to achieve uniform texture with zero residual bubbles, improving adhesive stability and reliability of electronic products.


Comparison Before and After Improvement

Before Improvement — Pain Points of Traditional Processes

For consumer‑electronics manufacturers, micro‑bubbles inside adhesives directly determine product quality and reliability. Conventional processing methods face multiple challenges:

• Stubborn micro‑bubbles hard to eliminate: Micro‑bubbles generated in adhesive stirring hardly escape naturally. Large quantities of bubbles remain even after hours of static placement, degrading potting and dispensing quality.

• Unstable product quality: Residual bubbles lead to voids and air pores after adhesive curing, resulting in deteriorated insulation and sealing performance, and even product failure in severe cases.

• Low efficiency of traditional stirring: Mechanical paddle stirring delivers poor bubble‑removal performance and requires repeated operations, greatly disrupting production rhythm.

• Secondary‑contamination risks: Traditional stirring paddles contact materials directly, introducing impurities and secondary contamination. Cleaning is cumbersome and heavy material waste occurs during batch switching.


Solution

• Vacuum Defoaming + Planetary Motion: Adopt rotation‑revolution planetary principle. Centrifugal force from revolution realizes defoaming while shear force generated by rotation‑revolution completes mixing. Vacuum pump extracts gas to form vacuum environment for thorough removal of nano‑scale micro‑bubbles.

• Non‑contact material processing: Non‑contact design avoids physical contact with materials, preventing secondary contamination and waste and preserving adhesive purity.

• PLC segment control: Multi‑segment PLC program control system stores multiple groups of stirring parameters to satisfy multi‑stage mixing‑defoaming requirements for diverse materials. Dedicated process programs can be called with one‑click operation.

• Precise regulation: High‑precision control system adjusts vacuum degree and stirring speed for different adhesive types and process requirements to secure optimal defoaming outcomes.


Advantages of Stirring‑Defoaming Machine

• High‑efficiency defoaming: Vacuum environment combined with planetary motion rapidly expels bubbles inside adhesives, lowering bubble content and enhancing adhesive quality and performance.

• Uniform mixing: Professional planetary stirring unit synergizes rotation and revolution to achieve sufficient and homogeneous adhesive mixing. Vacuum environment suppresses new bubble generation and guarantees consistency and stability.

• Precise control: PLC precise control system adjusts vacuum degree, rotation speed and duration according to adhesive types and process requirements for optimal defoaming performance.

• User‑friendly operation: Intuitive UI enables simple defoaming workflows. Easy cleaning and maintenance save time and labor costs.

• Non‑contact material handling: Non‑contact structure eliminates secondary contamination and waste and maintains adhesive purity.

• Customizable functions: Custom fixtures and programs are available upon customer requests to fit production demands for containers and materials of various specifications.
