SIENOX Powder Material Solutions

Working Condition Requirements

• Material Type: Powder materials (ceramic powder, metal powder, medicinal powder, food powder, catalyst powder, etc.)

• Initial State: Powder materials are compressed and agglomerated during storage and transportation. A large amount of air is trapped among powder gaps, resulting in poor powder flowability and dispersibility. Direct application tends to cause uneven filling, inconsistent sintering shrinkage, fluctuating tableting density and other issues.

• Processing Target: Uniformly remove interstitial air and agglomerated bubbles from powder materials to achieve uniform‑loose state, favorable flowability and excellent dispersibility, satisfying high‑precision process requirements for powder metallurgy forming, ceramic sintering, pharmaceutical tableting, food filling and so on.

Before Improvement — Pain Points of Traditional Processes

Powder materials are widely adopted in powder metallurgy, precision ceramics, pharmacy, food and other industries. Their flowability and dispersibility directly determine product quality. Nevertheless, powders are prone to caking and air entrapment in gaps during storage and transportation, bringing multiple challenges to conventional processing:

• Poor flowability caused by powder agglomeration: Powders cake after moisture absorption or compression, with compressed‑trapped air among particles, leading to poor flowability and uneven filling, which impairs subsequent forming or tableting quality.

• Agglomerated bubbles affecting density: Air in powder gaps forms agglomerated bubbles, triggering uneven shrinkage and large dimensional deviation during sintering; inconsistent density in pharmaceutical tableting interferes with drug‑release performance.

• Low efficiency of manual sieving: Traditional manual sieving or vibrating screens can only eliminate large‑particle agglomerates instead of micron‑scale bubbles trapped in powder gaps, featuring low processing efficiency.

• Dust flying causing environmental pollution: Dust flies during conventional turning‑over and sieving procedures, resulting in raw‑material waste, workshop pollution and health hazards for operators.

Solutions

• Vacuum Defoaming + Planetary Motion: Under vacuum environment, soft and uniform shearing and convection are generated through rotation‑revolution planetary motion to gradually extract interstitial air and agglomerated bubbles inside powders for thorough defoaming.

• Uniform‑loose Powder: 360° dead‑angle‑free mixing is realized by planetary motion. Powder particles are re‑dispersed under soft force field and restore uniform‑loose flow state.

• Significantly Improved Flowability: Treated powders deliver favorable flowability and excellent dispersibility with uniform filling and consistent forming performance.

• Dust‑free & Eco‑friendly Treatment: Processing is completed in vacuum sealed environment without dust flying, protecting raw materials and workshop environment.

Advantages of Stirring‑Defoaming Machine

• Efficient Removal of Interstitial Air: Vacuum environment combined with planetary motion effectively removes interstitial air and agglomerated bubbles of powders and restores powder flowability.

• Uniform‑loose Powder: Gentle and uniform rotation‑revolution planetary motion enables non‑destructive dispersion of powder particles without damaging particle morphology.

• Precisely Controllable Parameters: Rotating speed, time and vacuum degree are adjustable to precisely optimize process parameters for diverse powder characteristics.

• Significantly Improved Flowability: Treated powders feature favorable flowability and excellent dispersibility with uniform filling and consistent forming performance.

• High Efficiency & Time‑saving: The whole stirring‑defoaming process is finished within several minutes, greatly boosting production efficiency.

• Dust‑free & Eco‑friendly Treatment: Processing is completed in vacuum sealed environment without dust flying, protecting raw materials and workshop environment.
