UV Ink Defoaming Machine


Eliminate bubbles in UV ink before curing · High gloss & pinhole-free, low shear to prevent premature curing

Vacuum low-shear design with no temperature rise + One-time removal of microbubbles + Light-shielding operation to avoid premature curing

SIENOX UV ink defoaming solution addresses the high gloss and high transparency features of UV ink, where bubbles will form pinholes before curing. Vacuum low-shear defoaming is applied with low heat generation to prevent premature curing, delivering glossy and defect-free UV ink films suitable for high-quality printing such as cigarette package and label varnishing.

Why Do We Need a UV Ink Defoaming Machine

Traditional challenges: Heat generated by ordinary stirring causes premature thickening of UV ink. The ink thickens before defoaming is completed. Vacuum defoaming with low temperature, low shear and light shielding is required.

High-gloss UV Printing

UV ink features high gloss and high transparency. Even a single bubble before curing will create pinholes, craters and fish eyes on the ink film, ruining the high-gloss appearance.

Shear-sensitive UV System

UV ink is sensitive to shear heat. Heat generated by conventional high-speed stirring causes premature thickening and reaction of ink, degrading ink performance before defoaming is finished.

Varnishing for Cigarette Packages & Labels

UV varnishing for cigarette labels, wine labels and tags requires high gloss and zero defects. Any pinholes or pits will be directly rejected in downstream inspection.

✨ Traditional challenges: Heat produced by conventional stirring thickens UV ink in advance. The ink becomes viscous before defoaming completes. Vacuum defoaming with low temperature, low shear and light shielding is required.

Why Choose SIENOX UV Ink Defoaming Solution

Low Shear & Low Heat Generation

Non-contact low-speed vacuum stirring generates little heat, preventing premature curing or thickening of UV ink caused by shear heat.

Complete Microbubble Removal

Negative pressure of −98 kPa expands and floats microbubbles inside transparent UV ink for one-time removal, delivering high-gloss and pinhole-free ink films.

Light Shielding & Reproducible Process

Light-shielding operation throughout the whole process. 100 formula storage slots enable stable process replication for bulk UV ink production.

✨ The MIX series serves as 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

NotesOperation Instructions
Light-shielding OperationKeep light shielded during ink mixing, defoaming and transfer to prevent premature curing of UV ink.
Low-speed OperationLow-speed stirring is recommended to reduce shear heat and avoid premature thickening of ink.
Vacuum DurationControl vacuum time to prevent excessive volatilization of active monomers which may affect ink properties.
Slow Pressure ReliefRelease pressure slowly after defoaming to avoid re-foaming and fogging on ink surface.
