Flexographic Printing Ink Defoaming Machine
Resolve foam of water-based flexographic ink · Clear dots, pinhole-free and less foam accumulation
Physical vacuum defoaming without defoamer + Preserve adhesion of water-based system + Flexible color change for small batches
SIENOX flexographic ink defoaming solution targets the characteristic that water-based flexographic ink contains surfactants and foams easily. It removes foam by physical vacuum method without adding defoamers, so as not to impair ink film adhesion and printability, achieving uniform ink transfer of anilox rollers and clear halftone dots.
✓ CE certification ✓ ISO9001 Quality Management System ✓ RoHS compliance ✓ Custom voltage available (110V/220V)
Why Do We Need a Flexographic Ink Defoaming Machine
Water-based Flexographic PrintingWater-based flexographic ink contains surfactants and foams readily after circulating stirring, resulting in uneven ink transfer of anilox rollers and missing prints or streaks on solid and halftone areas. | Foam Accumulation & PinholesFoam accumulates on plate rollers and ink tanks, and forms pinholes and pits after drying, damaging print appearance and lamination strength. | Food Packaging PrintingWater-based ink for food packaging requires high purity. Defoamers cannot be added arbitrarily, otherwise migration may occur and compromise lamination adhesion and hygienic performance. |
✨ Traditional dilemma: Relying on defoamers to suppress foam tends to cause migration and impair ink film adhesion and lamination strength. Pure physical vacuum defoaming is required.
Why Choose SIENOX Flexographic Ink Defoaming Solution
No Defoamers AddedPure physical vacuum defoaming without introducing defoamers to protect the adhesion, lamination strength and hygienic properties of water-based systems. | Uniform Ink TransferEliminates foam on anilox rollers and ink tanks to achieve stable ink transfer and clear halftone dots, reducing missing prints and streaks. | Flexible Color ChangeFrequent color switching for small-batch multi-color orders. The C/ZK series supports fast ink formulation and defoaming for high production conversion efficiency. |
✨ The MIX series is an 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 |
| Appropriate Vacuum Level | Apply moderate vacuum for water-based ink defoaming. Excessive vacuum may impair ink wettability and drying performance. |
| Slow Pressure Relief | Release pressure slowly after defoaming to prevent foam re-entry and ink splashing. |
| No Defoamers Added | Rely primarily on vacuum defoaming. Avoid extra defoamers that may compromise adhesion and hygiene for food packaging. |
| Ink Circulation | Check ink transfer on anilox rollers after defoaming. Start batch printing only after stabilization. |
