The HDA high-speed robotic liquid paint electrostatic rotating bell spray gun is an advanced system used for automotive parts and new energy parts paint surface coating. Let me break down the key features and details:

Rotating Bell Spray System:
The system utilizes a rotating bell mechanism to disperse the coating evenly.
The coating is separated from the rotary cup through small teeth around the rotary cup, creating fibrous filaments.
Under the action of centrifugal force and high electric charge, the coating is micronized and evenly distributed in the spray space.
The positively charged coating is effectively adsorbed onto the workpiece, resulting in improved coating efficiency, evenness, and enhanced gloss of the coating film.
This system helps save paint, reduce VOC emissions, and lower costs.

Principle of Electrostatic Rotating Atomizing Bell Cup:
The system’s rotating atomizing bell cup operates based on electrostatic force.
Material is guided into the rotating cylinder by a high-voltage power supply.
Friction between the inner wall of the rotating cylinder and the material surface charges the material.
Centrifugal force during rotation generates micronized droplets.

The electric field and potential difference result in electrostatic force, aiding in efficient coating deposition
