The powder coating process involves several coordinated stages.
Surface Preparation
The surface must be cleaned before coating.
Typical preparation activities include:
- Removing dust
- Eliminating oils and grease
- Surface treatment
- Rinsing procedures
Powder Application
Electrostatic spray equipment applies powder particles to the product surface.
Curing Process
Heat cures the powder coating, creating a durable finished layer.
Cooling Stage
The coated component cools before inspection and handling.
