Applications

High-volume flat parts such as appliance panels, refrigerator and washer fronts
Small and medium parts: furniture hardware, aluminium profiles, switch cabinets
Thick-film parts: battery trays and energy-storage cabinets
Replacing worn guns on an existing line where transfer efficiency has dropped

How It Works

Corona charging: the electrode at the gun tip is held at negative high voltage, so powder leaves the nozzle charged and is attracted to the grounded part. Field strength, powder output and atomising air together set transfer efficiency — adjusting only one usually makes it worse.

Powder feed: fluidised hopper → Venturi pump → feed hose → gun. Conveying air and atomising air are regulated separately to prevent surging and clogging. Reclaimed powder must be sieved and tested before it is blended back.
