The powder coating process involves several steps:

1. Surface Preparation: The metal surface to be coated is thoroughly cleaned and prepared. This typically involves removing any dirt, grease, or rust.

2. Electrostatic Application: The powdered coating material is applied to the prepared metal surface using an electrostatic gun. The powder particles are charged, causing them to adhere to the metal surface.

3. Curing: The coated item is placed in an oven where the powder is heated. The heat causes the powder to melt and fuse to the metal surface, forming a durable coating.

4. Cooling: After curing, the coated item is allowed to cool before it is ready for use.

The specific curing temperature and time may vary depending on the type of powder coating and the desired properties of the finished product.
