Fast vacuum defoaming for low-viscosity ink + Stable plate surface with circulating ink supply + Reproducible batch stability
SIENOX gravure ink defoaming solution is developed for low-viscosity solvent-based and water-based gravure inks which are prone to foaming. It rapidly removes bubbles generated by circulating stirring under vacuum to reduce pinholes, blade streaks and plate clogging, maintaining stable ink color and clean plate surface for mass continuous production of flexible packaging.
✓ CE certification ✓ ISO9001 Quality Management System ✓ RoHS compliance ✓ Custom voltage available (110V/220V)
Why Do We Need Gravure Ink Defoaming Machine
Flexible Packaging Gravure Printing IndustryLow-viscosity ink used for gravure printing of plastic films, food bags and other flexible packaging tends to foam after circulating stirring. Pinholes and pits appear after printing, damaging appearance and lamination quality. | Plate Roller & Doctor Blade SystemBubbles adhering to plate rollers and blade grooves easily cause blade streaks and cell clogging, resulting in continuous streaks and plate defects as well as frequent shutdown for cleaning. | Mass Continuous ProductionGravure printing features high line speed and large batch volume, requiring stable ink defoaming and consistent ink color across batches. Bubble fluctuations will lead to massive waste products and material loss. |
✨ Traditional dilemma: Continuous ink circulation generates increasing foam. Adding defoamers during shutdown will compromise drying speed and lamination adhesion. Fast and stable vacuum defoaming is required.
Why Choose SIENOX Gravure Ink Defoaming Solution
Fast Defoaming for Low-Viscosity InkBubbles in low-viscosity solvent-based / water-based ink rise rapidly under vacuum with high defoaming efficiency, adapting to the fast ink supply rhythm of gravure printing. | More Stable Plate SurfaceInk feeding after defoaming reduces blade streaks, cell clogging and pinholes caused by bubbles adhering to the plate, achieving clean plate surface and lower reject rate. | Reproducible BatchesThe touch screen stores 100 groups of formulas. Defoaming parameters can be recalled with one click to guarantee consistent ink color and quality during mass production. |
✨ The MIX series is ideal defoaming equipment 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 |
| Vacuum Duration | Control vacuum defoaming time for solvent-based inks to prevent excessive solvent evaporation and viscosity rise. |
| Slow Pressure Relief | Release pressure slowly after defoaming to avoid splashing and re-foaming of low-viscosity ink. |
| Stable Ink Circulation | Start printing only after ink circulation stabilizes post defoaming to prevent initial color fluctuation. |
| Ventilation & Fire Prevention | Ensure adequate ventilation and fire protection when handling solvent-based ink. |
