Color Coating Line

Key Components and Steps in a Color Coating Line:

1. Uncoiling:

   • The process begins with uncoiling the metal substrate from large coils. These coils are fed into the line for processing.

2. Cleaning and Pretreatment:

   • The metal surface is cleaned to remove dirt, oil, and other contaminants. This is followed by a chemical pretreatment to improve the adhesion of the coating.

3. Coating Application:

   • The coating process typically involves the application of a primer and top coat. This can be done through various methods such as roller coating, spray coating, or dip coating.

4. Curing (Baking) Oven:

   • After the coating is applied, the metal passes through a curing oven where it is heated to a specific temperature. This process hardens the coating and ensures durability.

5. Cooling:

   • After curing, the coated metal is cooled down to solidify the coating before further processing.

6. Recoiling:

   • Finally, the coated metal is recoiled into large rolls for easy handling and transportation.
