Powder Spraying on The Surface of Various Metal Parts

You can rest assured to buy KwongTo Powder Spraying On The Surface Of Various Metal Parts from our factory. Here's an overview of the powder spraying process for metal parts:

Surface Preparation: Before powder spraying, the metal parts must be cleaned thoroughly to remove any dirt, oil, grease, or rust from the surface. Surface preparation techniques may include solvent cleaning, degreasing, sandblasting, or chemical treatment to ensure proper adhesion of the powder coating.

Powder Application: The powder coating material consists of finely ground particles of pigment and resin that are electrostatically charged and sprayed onto the metal parts using a specialized powder coating gun. The electrostatic charge causes the powder particles to adhere uniformly to the metal surface, creating a smooth and even coating.

Curing: After the powder coating has been applied, the coated metal parts are cured to fuse the powder particles together and create a durable, protective finish. Curing is typically done in a curing oven at elevated temperatures, usually between 300°F and 450°F (150°C to 230°C), for a specified period of time. During curing, the powder coating melts and flows to form a continuous film that bonds to the metal substrate.
