Mastering the Smallest Doses
Micro Gravimetric Feeder
Micro gravimetric feeders represent the pinnacle of accuracy in dispensing minute quantities of materials. Unlike volumetric methods, these advanced systems operate on the principle of continuous weight monitoring (Loss-in-Weight). This technology enables real-time, closed-loop control for unparalleled precision, making them indispensable where exact dosing is non-negotiable.

Micro-Gravimetric Powder Feeder
Demanding industries rely on micro gravimetric technology to overcome the limitations of conventional feeding:
Plastics & Polymers: Accurately injecting ultra-low levels of additives, masterbatches, or pigments.
Specialty Chemicals & Pharmaceuticals: Handling potent active ingredients, catalysts, or trace additives in synthesis and formulation.
Food & Nutraceuticals: Precisely incorporating flavors, vitamins, minerals, or micro-nutrients where even minor deviations impact taste, efficacy, or safety.

What sets micro gravimetric feeders apart is their ability to directly measure mass flow, dynamically adjusting feed rates based on actual weight loss. This eliminates errors from material density changes, bridging, or ratholing common in volumetric systems. Key capabilities include:
Ultra-Fine Resolution: Consistently dosing at gram levels, crucial for high-value or potent materials.
Continuous Accuracy: Maintaining tight tolerances (±0.25% to ±1% of setpoint) over extended runs, even with challenging powders, granules, or mini-pellets.
Process Stability: Providing real-time feedback and automatic recalibration, safeguarding against drift and ensuring repeatable results batch after batch.
