Uniquecoat® G4™
Gravimetric Powder Feeder
A versatile gravimetric powder feeder engineered for excellence in thermal spray processes such as HVOF, HVAF, Plasma, Cold Spray, Laser Cladding, and a broad spectrum of industrial applications. The G4 automatically maintains the feed rate, adjustable in standard or customary units. Its patented, seal-free feeding mechanism ensures smooth, pulseless powder flow that remains consistent over time.

Key Features
Gravimetric G4 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.
🟢 Gravimetric and Volumetric Modes of Operation
Allows flexible selection between gravimetric and volumetric feeding, depending on process requirements.
🟢 Patented Powder Feed Design
Ensures smooth, pulseless powder flow and allows quick powder start and stop with no afterflow.
🟢 High Feed Accuracy
Delivers precise powder delivery with most powders.
🟢 Quick Start/Stop
Starts powder flow 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.
🟢 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.
🟢 Large Recipe Storage Capacity
Stores and recalls multiple powder calibration profiles for fast process setup.
🟢 Dump Powder Function
Allows quick, convenient hopper emptying at the touch of a button.
🟢 Setpoint & Real-Time Feed-Rate Display
Provides clear visibility of both setpoint and live process feedback.
🟢 Touchscreen Interface
Intuitive control panel for simple, user-friendly operation.
🟢 Backpressure Insensitivity
Maintains stable, uniform powder flow regardless of backpressure variations.
🟢 ASME Code Compliance
Designed and built in accordance with ASME pressure vessel standards.
🟢 Optional Add-Ons
– Carrier-gas mass flow controllers
– Analog I/O or RS-232 interface for remote control and automation
