Components of an Electrostatic Powder Spraying System

Components of an Electrostatic Powder Spraying System

Powder Feed System

Hopper: Stores the dry powder coating material.

Agitator: Ensures the powder remains free-flowing and does not clump.

Feeder: Regulates the flow of powder to the spray gun.

Spray Gun

Electrostatic Generator: Provides the high voltage necessary to charge the powder particles.

Nozzle: Atomizes the powder and directs it toward the workpiece.

Air Supply: Compressed air helps to propel the powder particles.

Powder Recovery System

Filter Cartridge: Captures overspray and recirculates it back to the hopper.

Fan: Creates a vacuum to draw oversprayed powder through the filter.

Booth

Enclosure: Provides a controlled environment for the spraying process, minimizing contamination and improving safety.

Lighting: Ensures good visibility during the application process.

Exhaust System: Removes fumes and particulates from the booth.

Curing Oven

Heating Elements: Provide the necessary heat to melt and cure the powder coating.

Temperature Control: Ensures uniform heating and proper curing conditions.

Conveyor System: Moves the coated parts through the oven.

Control Panel

User Interface: Allows operators to control and monitor the entire system.

Sensors: Monitor temperature, pressure, and other critical parameters.

Safety Features: Includes emergency stop buttons and interlocks.
