Why Eliminate Bubbles in Materials

Residual microbubbles during material lamination directly impair product quality.

LCD Polarizer Lamination Industry

Residual bubbles in OCA optical adhesive during lamination of LCD polarizer and glass substrate cause uneven light transmission and mottled display, deteriorating screen quality. Pressurized defoaming shrinks and dissolves bubbles via pressure; heat reduces OCA viscosity to release bubbles. The φ400 small chamber suits small polarizer sample debubbling for quick process parameter verification in R&D.

Electronic Component Packaging Industry

Bubbles in encapsulation adhesive create voids, allowing moisture ingress and device failure. Repeated parameter tuning is required in R&D. Three working modes support pressurize-first or heat-pressure sync per adhesive properties. Fast pressurization of small chamber shortens trial cycles for fast process confirmation.

Medical Device Industry

Bubbles in medical bonding impair biocompatibility and structural strength; small-batch tests are needed for trial production. The precision filter avoids secondary contamination. The φ400 chamber fits lamination debubbling of small medical samples, with audible & visual alarms for safe operation.

✨ Dilemmas of Traditional Defoaming Methods: In the R&D and trial production stage, professional pressurized defoaming equipment is usually unavailable. Natural bubble removal by long-time static waiting results in low efficiency. Ordinary ovens only provide heating without pressurization, making interfacial bubbles hard to eliminate. Inaccurate temperature control causes unstable fluidity of OCA adhesive, leading to poor repeatability of process parameters.

Why Choose SIE-RX4-400

Solve R&D efficiency and quality pain points via rapid pressurization, flexible modes and clean trial production.

Small Chamber & Rapid Pressurization

φ400×400mm cylindrical chamber with approx.75L volume. Pressurize to 0.6MPa in 5 mins and release pressure within 2-3 mins, single cycle takes 35-40 mins for fast turnaround. Fast pressure rise & drop enables rapid iteration of process parameters in R&D trials. Multiple test groups can be finished per day to shorten R&D cycles.

3 Flexible Switchable Modes

Three working modes available: A. Pressurize first then heat; B. Heat and pressurize simultaneously; C. Heat first then pressurize. Materials respond differently to pressure and temperature. Select proper mode according to material properties. Microcomputer control supports parameter storage & reproduction to help confirm optimal process recipes.

Precision Filter for Contamination Prevention

Incoming air passes through precision filter before entering chamber to avoid dust impurity contamination of test samples. R&D samples are high-value and limited in quantity; contamination may ruin the whole batch. The precision filter maintains clean trial environment and improves test success rate.

✨ If your application involves R&D trials, small sample lamination verification and process parameter tuning, RX4-400’s small chamber rapid pressurization and three flexible modes enable fast iteration.

Working Principle

Pressure and heat eliminate bubbles generated during lamination and boost adhesion between different materials.

Step 1: Pressurization & Heating (3 modes optional): Choose pressurize first then heat, heat and pressurize simultaneously, or heat first then pressurize according to material properties. Resistive heating combines with pressure to build debubbling conditions.

Step 2: Pressure Holding for Debubbling: Maintain constant pressure and temperature. Pressure compresses and dissolves bubbles at lamination interface, while heat reduces material viscosity to help bubbles escape.

Step 3: Pressure Relief & Stabilization: Slowly release pressure to atmospheric level. Adhesion between materials is strengthened and interfacial bubbles are removed.


Simple 3 steps: Pressurization & Heating → Pressure Holding Debubbling → Pressure Relief & Stabilization, remove lamination bubbles and improve adhesion.

  • How does the stirring and defoaming machine work?

    The SIENOX stirring and defoaming machine performs defoaming through centrifugal force at revolution and stirring through shear force formed by revolution and rotation,

    Assisted by a vacuum pump to extract gas and achieve a vacuum state, removing nanoscale tiny bubbles. No contact with materials, no secondary pollution, and no secondary waste.

  • What is the function of a defoaming machine?

    A defoaming machine is a device used to remove bubbles from liquids. Its function is to assist in the liquid mixing, reaction, coating, printing, infusion and other process steps in the production process, avoiding the generation of bubbles and their impact on the final product. In many industrial and laboratory environments, removing bubbles is essential as they may have a negative impact on product quality, such as affecting surface tension and stability. Defoaming machines typically use various techniques such as vibration, ultrasound, centrifugation, etc. to achieve effective bubble removal. It has a wide range of applications, including but not limited to semiconductors, solar energy, optics, biotechnology, materials science, etc.
