Why Remove Bubbles From Materials
Microbubbles remaining during material lamination directly impair product quality.
LCD Polarizer Lamination IndustryResidual bubbles in OCA optical adhesive cause uneven light transmission and mottled display when laminating LCD polarizers and glass substrates, degrading screen quality. Pressurized defoaming shrinks and dissolves bubbles under pressure; heat reduces OCA viscosity to discharge bubbles. The φ300 small chamber fits small polarizer samples for fast R&D parameter verification. | Electronic Component Packaging IndustryBubbles inside encapsulation glue create voids. Moisture intrusion leads to component failure, requiring repeated R&D parameter debugging. Three selectable working modes match adhesive properties: pressurize-first or heat-pressurize sync. Fast small-chamber cycling shortens trials to find optimal encapsulation processes. | Medical Device IndustryBubbles in medical bonding lamination hurt biocompatibility and structural strength; small batches are used for trial validation. The precision filter prevents secondary contamination. The φ300 chamber suits small medical sample lamination, with audible & visual alarms for safe operation. |
✨ Dilemmas of conventional defoaming: R&D trials lack dedicated pressurized defoamers. Natural bubble escape by standing takes long with low efficiency; ordinary ovens heat without pressure and cannot remove interfacial bubbles. Poor temperature accuracy causes unstable OCA flow and unrepeatable parameters.
Why Choose SIE-RX3-300
Solves R&D efficiency & quality pain points via fast pressurization, flexible modes and clean trials.
Small Chamber Rapid Pressurizationφ300×300mm cylindrical chamber of approx.75L, pressurizes to 0.6MPa in 5 mins and depressurizes within 2-3 mins. Single cycle takes 35-40 mins for fast turnaround. Fast pressure rise/drop enables quick iteration of process parameters, multiple test runs per day to shorten R&D cycles. | 3 Switchable Working ModesThree working modes available: A.Pressurize first then heat; B.Heat and pressurize simultaneously; C.Heat first then pressurize. Materials respond differently to pressure & temperature. Select modes by material features, microcomputer saves repeatable parameters to identify optimal processes. | Precision Filter for Contamination PreventionInlet air passes through precision filter before entering chamber to protect samples from dust impurities. R&D samples are costly and limited; single contamination may ruin the whole batch. Precision filtration maintains clean environment and improves test success rate. |
✨ If your work involves R&D trials, sample lamination & parameter tuning, RX3-300 enables fast iteration with rapid pressurization and 3 switchable modes.
Working Principle
Pressure and heat remove lamination bubbles and boost adhesion between diverse materials.
Step 1: Pressurization & Heating (3 optional modes): Choose pressurize-first, heat-pressurize sync or heat-first according to material properties. Resistive heating plus pressure builds defoaming environment. Step 2: Pressure Holding for Defoaming: Maintain constant pressure & temperature. Pressure shrinks and dissolves interfacial bubbles; heat reduces material viscosity to release bubbles. Step 3: Pressure Relief & Stabilization: Slowly release pressure to atmospheric level. Material adhesion improves and lamination bubbles are eliminated. Simple 3 steps: Pressurize & Heat → Hold Pressure for Defoaming → Depressurize & Stabilize, remove lamination bubbles and strengthen adhesion. | ![]() |

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.
