Why Must Microbubbles in Materials Be Eliminated?

Residual micro‑bubbles within materials directly affect the yield and performance of end‑products.

Electronic Component Manufacturing

In SMT assembly processes, micro‑bubbles inside solder paste cause voids and cold solder joints, reducing soldering reliability. Bubble expansion during reflow soldering leads to defects such as solder splatter and bridging. For precision components, excessive void ratio inside solder joints may trigger device failure under thermal cycling and lower overall board yield.

Medical Device Manufacturing

Bubbles in medical‑grade silicone and bio‑adhesives compromise dosage accuracy and consistency, which may result in medication deviation. Bubbles inside ointment gels cause uneven filling and inconsistent net content for each unit. For implant‑grade materials, tiny bubbles may also bring risks to biocompatibility.

3D‑Printing Manufacturing

Micro‑bubbles in photosensitive resins form defect spots within printed layers, weakening mechanical strength and surface quality of finished parts. During large‑volume printing, bubbles create visible streaks and pits on cured interfaces. Bubbles in metal‑powder slurries raise internal porosity of sintered components and deteriorate final‑part density.

✨ Challenges of conventional mixing methods: Manual stirring or standard impeller mixing actively entrains air, generating more bubbles as mixing proceeds. Static degassing takes substantial time with limited effectiveness. Therefore, a "non‑contact" planetary mixing‑defoaming solution is required, which separates bubbles via centrifugal force while completing material mixing.

Why Choose SIE‑MIX90

Three Core Advantages for Medium‑Capacity Full‑Range Vacuum Defoaming

Large‑Capacity for Production

With a 1000 mL processing volume, it meets requirements for pilot scale‑up and small‑batch production in a single run. The dual‑cup design enables simultaneous processing of two different materials or doubled throughput to boost production‑line efficiency. Combined with 2000 rpm and fixed speed ratio, it guarantees consistency and repeatability for batch processing.

Modular Expansion

Optional heating/cooling temperature control and MES networking system allow flexible configuration according to process requirements. One single unit covers multiple application scenarios from pilot validation to mass‑production roll‑out and reduces redundant equipment investment. The temperature‑control module fits heat‑sensitive and high‑viscosity materials, while the vacuum module improves micro‑bubble removal performance.

Reliability & Durability

Unique transmission design reduces vibration and noise. Built‑in balance sensors dynamically correct operational eccentricity to ensure stable performance during long‑term batch runs. Imported key components deliver high durability, lowering maintenance frequency and operating costs.

✨ The SIE‑MIX90 integrates three core capabilities: large‑volume processing, modular expansion and stable operation. It serves as an ideal equipment for the whole phase from pilot validation to small‑batch mass production.

Working Principle

Synchronized operation of dual‑driven revolution and rotation enables one‑step completion of mixing and defoaming.

Step 1: Centrifugal Force Generated by Revolution 

The revolving plate rotates at high speed to generate strong centrifugal force on materials inside the container, driving full‑volume material convection for macro‑mixing. Meanwhile, centrifugal force pushes low‑density bubbles toward the rotation axis to gather and escape. 

Step 2: Shear Force Provided by Rotation 

Containers rotate around their own axis to produce directional shear force, breaking up agglomerated particles to achieve micro‑dispersion. Precisely calculated revolution‑to‑rotation speed ratio ensures high‑efficiency mixing across the whole volume. Shear force thins bubble membranes and accelerates bubble rupture. 

Step 3: Vacuum Assistance for Enhanced Performance 

Chamber pressure drops to ‑98 kPa, increasing pressure difference inside and outside bubbles. Micro‑sized bubbles expand and rupture rapidly. The vacuum system continuously exhausts gas to further improve material density. 


Revolution and rotation run simultaneously. Materials complete the full‑cycle process of "Mixing → Dispersion → Defoaming" inside sealed containers. Optional vacuum module improves micro‑bubble removal performance.

  • 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.
