Screen Printing Ink Defoaming Machine
Resolve bubbles and screen clogging of screen printing ink · Uniform ink film, pinhole-free and excellent mesh passing property
Vacuum stirring and defoaming for high-viscosity ink + Deagglomerate fillers to improve mesh passing + Suitable for milliliter-level sampling
SIENOX screen printing ink defoaming solution solves the pain points of screen printing ink including high viscosity, large amount of pigment fillers and air entrapment during scraping and stirring. Stirring and defoaming are completed simultaneously under vacuum to break filler agglomerates, forming uniform thick ink films and smooth mesh penetration, lowering the occurrence of screen clogging, pinholes and local ink shortage.
✓ CE certification ✓ ISO9001 Quality Management System ✓ RoHS compliance ✓ Custom voltage available (110V/220V)
Why Do We Need a Screen Printing Ink Defoaming Machine
General Screen PrintingScreen printing ink has high viscosity and abundant pigment fillers. Air trapped during scraping and ink mixing leads to screen clogging, pits and pinholes on ink film, damaging pattern integrity. | Thick-film Printed PartsFor thick-film printing on membrane switches, nameplates, PC and glass, bubbles cause local ink shortage and pinholes, reducing ink film adhesion and weather resistance. | Multi-variety & Small-batch ProductionScreen printing orders are often multi-variety, small-batch with frequent color changes. A fast sampling defoaming method with reproducible parameters is required. |
✨ Traditional challenges: Manual stirring of high-viscosity ink still entraps air after long mixing. Screen clogging and pinholes occur once printing starts, leading to high scrap rates. Vacuum stirring is required for high-viscosity screen printing ink.
Why Choose SIENOX Screen Printing Ink Defoaming Solution
Defoaming for High-viscosity InkVacuum stirring handles high-viscosity screen printing ink, treating bubbles and filler agglomerates at the same time for smoother mesh passing. | Uniform Ink FilmBreaks up pigment filler agglomerates to achieve consistent ink film thickness without pinholes or pits, and provides stronger adhesion for thick films. | Sampling-friendlyC/ZK series supports milliliter-scale sampling, enabling fast color switching for multi-variety small batches. MIX series for scale-up mass production. |
✨ The MIX series serves as an ideal defoaming device for offset printing ink from color matching to bulk ink supply.

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.

Precautions for Use
| Notes | Operation Instructions |
| Heating to Reduce Viscosity | High-viscosity screen printing ink can be properly heated to lower viscosity before defoaming, improving mesh passing and dispersion performance. |
| Standing Before Printing | It is recommended to stand for several minutes after defoaming to allow residual microbubbles to rise before screen printing, reducing pinholes. |
| Loading Capacity | Match the cup loading volume with rotation speed to prevent sedimentation and uneven dispersion of high-filler ink. |
| Slow Pressure Relief | Release pressure slowly after defoaming to avoid re-foaming and splashing of paste ink. |
