In the ink manufacturing industry, the uniformity of pigment dispersion and control of residual bubbles are critical determinants of printing quality. With its unique revolution-and-rotation motion and non-contact design, planetary stirring defoaming machines serve as an ideal solution for high-precision ink production, especially suitable for the preparation of nano-scale pigment dispersion, UV inks and high-viscosity special inks.

Revolution-and-Rotation Motion: Achieve Uniform Ink Dispersion
The core principle of planetary stirring defoaming machines lies in the compound motion of the container itself. Inside the vacuum chamber, the material container performs both revolution and rotation simultaneously. Revolution drives the container to rotate around the central axis of the equipment, while rotation spins the container at high speed about its own axis. The combination creates a complex centrifugal force field. Under this motion pattern, ink materials realize three-dimensional flow relying on centrifugal force and gravity without the intervention of mechanical stirring paddles. For high-viscosity inks, structural damage caused by traditional blade shearing can be avoided. For nano-scale pigments, particle agglomeration can be overcome to guarantee submicron dispersion uniformity, greatly improving the color saturation and printing stability of inks.

Non-contact Design: Ensure Ink Purity and Process Controllability
The equipment adopts a fully enclosed non-contact power transmission system. Power is transferred between the container and driving mechanism via magnetic coupling, completely isolating contamination risks from metal friction debris or lubricating oil. This design meets the cleanliness requirements of food-grade and medical inks, and adapts to the preparation of solvent-containing volatile inks. Meanwhile, the vacuum defoaming module works in tandem with the motion system to extract bubbles during mixing, controlling the gas content of ink below 0.01% and effectively eliminating printing defects such as pinholes and orange peel patterns. The intelligent temperature control system allows users to precisely adjust process temperature and prevent thermally sensitive components such as photoinitiators from deactivation due to local overheating.

SIENOX: Benchmark for Customized Solutions in the Ink Industry
To meet the special demands of the ink sector, SIENOX’s series of planetary stirring defoaming machines adopts a modular design to provide one-stop coverage from laboratory R&D to mass production. Its exclusive "dynamic vacuum gradient control" technology automatically adjusts defoaming intensity according to ink viscosity to prevent pre-polymerization of UV resin during defoaming. The patented eccentric rotation structure boosts the dispersion efficiency of high-solid metallic inks by over 40%. At present, SIENOX equipment has been successfully applied in high-end fields such as electronically printed conductive inks and glass screen-printing inks. Its data traceability system records process parameters of each batch to reliably guarantee consistent ink quality.

As printing technologies advance toward high resolution and environmental friendliness, planetary stirring defoaming machines play an increasingly vital role in ink material innovation. Through continuous technological iteration, brands like SIENOX are driving ink manufacturing from experience-oriented production into a new era of data-driven intelligent manufacturing.
