Why Must Microbubbles in Materials Be Eliminated?
Micro bubbles trapped inside materials directly impair product performance and the accuracy of process validation
Automotive ElectronicsBubbles in epoxy potting compounds for automotive ECUs and sensors cause partial discharge and degraded insulation, leading to component failure under long‑term vehicle vibration. Automotive‑grade standards demand void‑free potting layers; micro‑bubbles directly result in failed reliability tests. | Wearable DevicesIn dispensing processes for smartwatches and TWS earbuds, adhesive bubbles weaken bonding strength and trigger detachment during drop tests. Miniature packaging requires highly uniform glue layers; invisible micro‑bubbles also reduce production yield. | Composite MaterialsBubbles inside resin‑based composites turn into internal voids after curing, lowering interlaminar shear strength and impact resistance. Bubbles within prepreg resin impair fiber wet‑out and cause unsatisfactory mechanical performance of finished composites. |
✨ Drawbacks of traditional methods: Manual / impeller mixing entrains air; static degassing is slow and ineffective. Fixed‑ratio machines yield inconsistent results. Adjustable‑ratio planetary system tunes speed ratio for material‑specific mixing‑defoaming.
Why Choose SIE-MIXF301
Three Core Highlights for R&D Pilot Process Optimization
Adjustable Speed RatioThe key advantage of MIXF301 lies in freely adjustable revolution‑rotation speed ratio. Materials vary greatly in viscosity, particle size and density, and fixed‑ratio machines cannot deliver satisfactory mixing‑defoaming performance for all materials. With tunable speed ratio, researchers can set proper revolution‑rotation proportion for each material, strike a balance between mixing efficiency and defoaming effect, and realize process parameter optimization. | Process ValidationThe 300 mL capacity fits sample preparation in R&D and pilot‑scale tests. It provides sufficient volume for parameter verification without excessive material waste. 100‑recipe memory saves tuned speed‑ratio settings in one click. Different parameters for various materials can be quickly recalled for result reproduction. One unit covers the whole workflow from R&D exploration to pilot validation. | Wide CompatibilitySingle MIXF301 can replace multiple fixed‑ratio units. Tunable speed ratio adapts to adhesives, slurries, resins and other materials. Dual‑jar design processes two samples simultaneously for comparative experiments. Non‑contact mixing lowers contamination risk. Switch between materials simply by changing vessels without cleaning, ideal for frequent material‑switching in R&D labs. |
✨ Integrating adjustable speed ratio, process validation and flexible compatibility, the MIXF301 serves as an ideal device for material process parameter optimization and verification in R&D and pilot-scale stages.
Working Principle
Dual synchronous revolution and rotation drive with adjustable speed ratio enables flexible optimization for various materials.
Step 1: Centrifugal Force from Revolution The rotary plate spins at high speed and generates strong centrifugal force for materials inside the container, driving full convection to achieve macro mixing. Meanwhile, centrifugal force pushes low-density bubbles toward the rotating axis to gather and escape. Step 2: Shear Force from Rotation The container rotates around its own axis to produce directional shear force, breaking agglomerated particles for micro dispersion. Shear force also thins bubble membranes and accelerates bubble rupture. Step 3: Speed Ratio Adjustment for Optimized Performance The speed ratio between revolution and rotation can be freely adjusted according to material properties. Higher revolution ratio strengthens centrifugal defoaming for high-viscosity materials; higher rotation ratio enhances shear dispersion for easily agglomerated materials. Tuning the speed ratio balances mixing and defoaming performance. Revolution and rotation run synchronously. Materials complete the full workflow of "Mixing → Dispersion → Defoaming" inside the sealed container. Adjustable speed ratio enables one machine to fit multiple material processes without purchasing extra equipment. | ![]() |

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.
