Uniquecoat® G10L™ Gravimetric Powder Feeder for Low Feed Rates
The G10L™ gravimetric powder feeder is specifically engineered for Laser Cladding applications, where exceptionally high accuracy at very low feed rates is paramount.
G10L Powder Feeder
Key Features – G10L Gravimetric Powder Feeder
🟢 Automatic Feed Rate Control
Maintains the desired feed rate, configurable in grams per second, grams per minute, kilograms per hour, or pounds per hour.
🟢 Innovative Powder Feeding Mechanism
Delivers continuous, pulseless powder flow and stable performance across the full feed-rate range, including ultra-low rates (patent pending).
🟢 Exceptional Feed Accuracy
Delivers precise and repeatable powder delivery with most powders.
🟢 Quick Start/Stop
Starts quickly and stops cleanly with no powder afterflow, providing controlled and efficient operation.
🟢 Powder Calibration Function
Enables quick powder startup at the target feed rate, eliminating long stabilization periods.
🟢 Built-In Load Cell Calibration
Enables quick recalibration and maintains precise measurement accuracy.
🟢 Backpressure Insensitivity
Maintains stable, uniform powder flow regardless of system backpressure variations.
🟢 Gravimetric & Volumetric Modes
Offers flexibility to switch between gravimetric and volumetric feeding as required.
🟢 Feed-Rate Startup Ramp
Provides controlled increase or decrease of powder feed rate over a selected time period, enabling uniform coating thickness on tapered parts or discs.
🟢 No Wearing Seals
Seal-free design eliminates consumable parts and reduces maintenance requirements.

G10L Low Feed Rate Stability Demonstration with Metal-Alloy Powders
This video demonstrates the stable delivery of Stellite 6 (15–45 µm) metal-alloy powder through a 2 mm nozzle at multiple feed rates with a 10 L/min nitrogen carrier gas flow, supplied by the G10L powder feeder. The results highlight the G10L’s suitability for low-rate feeding of metal alloy powders - such as those used in precision laser cladding applications.
This demonstration video showcases the G10L™ feeder’s control screen during operation at various ultra-low feed rates of metal alloy Stellite 6 (15–45 µm). The footage is intentionally extended to allow close observation of feed-rate stability over time. It clearly demonstrates how the feeder’s electronics dynamically adjust motor speed to keep the actual feed rate aligned with the setpoint, ensuring precise and consistent powder delivery even at the lowest flow settings.
