Why Precise Mixing Is Required

Uneven mixing of powder materials directly affects end‑product performance

Ceramic Industry

Uneven mixing of components in alumina, zirconia and other ceramic powders causes inconsistent sintered density, cracking and fluctuating mechanical properties. The 3D powder mixer achieves homogeneous blending for ceramic powders of different specific gravities and particle sizes, ensuring consistent composition and stable performance of sintered bodies. It meets quality standards for small‑and‑medium‑batch production and reduces reject rates.

Pharmaceutical Industry

Uneven blending of active ingredients and excipients in pharmaceutical powder formulas leads to tablet content deviation, impairing efficacy consistency and pharmaceutical compliance. The 3D powder mixer homogenizes powders in a dust‑proof sealed environment to guarantee uniform content distribution per batch and meet strict mixing‑homogeneity requirements for pharmaceutical production with reliable batch‑to‑batch consistency.

Magnetic Material Industry

Poor mixing of NdFeB and other permanent‑magnet powders results in fluctuating magnetic properties and unsatisfactory batch consistency for customer acceptance. The 3D powder mixer homogenizes magnetic powders of varied particle sizes, delivering consistent magnetic performance and stable batches of sintered magnets. It fulfills quality requirements for small‑and‑medium‑batch production and lowers scrap rates.

✨ Pain Points of Traditional Powder Mixing Small-capacity equipment suffers from insufficient single-batch throughput, resulting in low efficiency for small and medium-batch orders due to repeated batch mixing. V-type and traditional 3D mixers are difficult to clean and time-consuming for material replacement. Open mixing operation causes flying dust, leading to environmental pollution and raw material loss. In addition, poor batch-to-batch consistency greatly affects product acceptance and delivery.

Why Choose SIE‑HF5L

Solve Core Pain Points of Powder Mixing for Small‑medium‑batch Production

5L Large Capacity for Higher Efficiency

5L standard vessel with max. volume of 4500ML. Its single‑batch throughput is more than doubled compared with 2L models, reducing mixing cycles and boosting efficiency for small‑medium‑batch production. The 5000ML chamber fits various standard jars. Adapters and jar stoppers are available for mounting small vessels to meet diverse volume requirements for multi‑purpose use.

9KG Heavy‑load for Denser Materials

Designed for heavy‑duty powder mixing. Heavy‑specific‑gravity materials such as metal and ceramic powders can be mixed stably within 5L volume. 3D compound motion delivers dead‑zone‑free homogeneous blending for materials of different densities. Supports dry‑dry, dry‑wet and wet‑wet sample mixing for broad application scope.

Intelligent Control for Reproducible Batch Stability

Microcomputer control system with touch‑screen operation, stores up to 10 recipe sets. One‑click parameter recall for frequent material change‑over to eliminate manual setting errors. Forward‑reverse dual‑process operation, adjustable duration from 0‑50 minutes in 1‑second increments with cycle mode. Auto home‑position stop after cycle completion to ensure consistent operation for every batch. Visual protective cover with safety interlock: machine stops immediately once cover is opened for operator safety.

✨ HF5L is your ideal choice for small‑medium‑batch production requiring high‑capacity efficient mixing, frequent material change‑overs or heavy‑duty material processing

Working Principle

Uniform material mixing is achieved via multi‑dimensional rotational, translational and tumbling movements inside fully sealed vessels

Step 1: 3D Movement in Sealed Vessel
The driving shaft drives rapid tumbling and swinging of materials inside the sealed vessel. Materials perform three‑dimensional compound motions including circumferential, radial and axial movements within the cylinder. The sealed structure prevents dust leakage and ensures a clean working environment.

Step 2: Uniform Diffusion via Multi‑directional Flow
Various materials flow, diffuse, accumulate and intermix under 3D compound motion. Materials with different specific gravities and particle sizes get fully contacted and blended to achieve dead‑zone‑free homogeneous mixing.

Step 3: Timed Stop & Home‑position Return
The unit stops automatically upon completion of set time and returns to home position, ensuring consistent discharging position for every batch. Dust‑free overall operation, easy cleaning, shorter mixing time and better mixing performance.


Three simple steps: Sealed 3D Motion → Multi‑directional Flow & Diffusion → Timed Home‑position Discharge for dead‑zone‑free homogeneous mixing. Forward‑reverse cycle operation is supported for repeated cycles until target homogeneity is reached.

  • 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.
