Why Must Microbubbles in Materials Be Eliminated?

Residual micro‑bubbles degrade end‑product quality directly

LCD Polarizer Lamination Industry

During the lamination of LCD polarizers with glass substrates, residual bubbles in OCA optical adhesive cause uneven light transmission and display haze, affecting screen display quality. Pressure defoaming compresses and dissolves bubbles through pressure, while temperature reduces OCA adhesive viscosity to assist bubble expulsion. The φ400 small chamber is suitable for sample lamination defoaming of small-size polarizers during the R&D stage, enabling rapid verification of process parameters.

Electronic Component Packaging Industry

Bubbles in electronic component packaging adhesive cause voids in the packaging layer, and moisture intrusion leads to device failure, requiring repeated process parameter adjustment during the R&D stage. The three working modes of pressure defoaming allow selection of pressurize-first-then-heat or simultaneous heating and pressurization based on packaging adhesive characteristics. The small chamber's rapid pressure rise shortens the prototyping cycle, helping R&D teams quickly determine the packaging defoaming process solution.

Medical Device Industry

Bubbles in medical device bonding and lamination affect biocompatibility and structural strength, requiring small-batch verification of defoaming effectiveness during the prototyping stage. The pressure defoaming precision filter prevents secondary contamination of products, the φ400 chamber is suitable for sample lamination defoaming of small-size medical devices, and the audible-visual-light alarm ensures safe and controllable prototyping processes.

✨ The dilemma of traditional defoaming: during the R&D prototyping stage, there is a lack of professional pressure defoaming equipment. Relying on standing still to wait for bubbles to escape naturally takes a long time and has low efficiency; ordinary ovens only heat without pressurizing, making it difficult to expel bubbles from the lamination surface; inaccurate temperature control causes large variations in OCA adhesive fluidity, making process parameters difficult to reproduce stably.

Why Choose SIE-RX4-600

Address the pain points of efficiency and quality in the R&D trial‑production phase from three dimensions: rapid pressure rise, flexible modes, and clean trial‑production.

Small‑chamber Rapid Pressure Rise

The φ400×600 mm cylindrical chamber has a volume of approximately 75 L. It reaches 0.6 MPa within 5 minutes, completes pressure relief in 2‑3 minutes, and enables fast cycle turnover of 35‑40 minutes per cycle. Thanks to fast pressure rise and drop in the small chamber, process parameters can be iterated rapidly during R&D trial‑production. Multiple sets of conditional tests can be finished within one day to shorten the R&D cycle.

Flexible Switching Among Three Modes

Three working modes are available: A. Pressurize first, then heat up; B. Heat up and pressurize simultaneously; C. Heat up first, then pressurize. Different materials respond differently to pressure and temperature. The three modes can be flexibly selected according to material properties. Parameters controlled by the microcomputer can be stored and reproduced to assist R&D teams in identifying feasible process solutions.

Anti‑pollution by Precision Filter

Inlet air passes through a precision filter before entering the chamber, preventing dust and impurities in the air from contaminating trial‑production samples. Samples in R&D trial‑production are high‑value and low‑volume; a single contamination incident may waste the entire batch. Precision filtration ensures a clean trial‑production environment and improves trial‑production success rates.

✨ If your scenarios include R&D trial‑production, small‑sample lamination verification and process‑parameter debugging, the rapid pressure rise of the RX4‑600 small chamber and flexible switching among three modes enable you to achieve rapid iteration.

Working Principle

Remove bubbles generated during lamination by pressure and temperature to enhance bonding strength between different materials.

Step 1: Pressurization and Heating (Three‑mode Optional)
Select pressurize‑first‑then‑heat, simultaneous heating‑pressurization or heat‑first‑then‑pressurize according to material properties. Resistive heating cooperates with pressurization to build a defoaming environment. 

Step 2: Pressure‑holding Defoaming
Maintain constant pressure and temperature. Pressure compresses and dissolves bubbles on the bonding interface, while temperature reduces material viscosity to help bubbles escape from the bonding surface. 

Step 3: Pressure Relief and Stabilization
Slowly release pressure to normal atmospheric pressure. Adhesion between materials is enhanced and bubbles on the bonding interface are eliminated. 


Three simple steps: Pressurization & Heating → Pressure‑holding Defoaming → Pressure Relief & Stabilization, to eliminate bonding bubbles and strengthen adhesive force.
