Machine Type Classic Epoxy Powder Electrostatic Powder Coating Machine for Metal Surface

Powder coating machine electrostatic powder coating machinery
 
The working principle of the electrostatic powder coating machine mainly includes the following steps:
Powder Supply: The powder coating is stored in a dedicated storage container and delivered to the spray gun through airflow.
Electrostatic Charging: The electrode inside the spray gun uses a high-voltage power supply to charge the powder coating with static electricity, giving it a negative charge.
Spraying Process: The charged powder coating is sprayed out through the nozzle, forming fine coating particles. These particles are attracted to the positively charged surface of the workpiece due to electrostatic forces, ensuring even adhesion.
Curing: The coated workpiece is then placed in a curing oven, where the powder melts and flows out at high temperature, ultimately forming a hard coating.
Recovery and Reuse: Unattached powder can be collected through a recovery system and fed back into the spraying process, increasing material utilization.
Through these steps, the electrostatic powder coating machine achieves high efficiency, low waste, and excellent coating quality.
