Powder Coating Process

1. Surface Treatment

Before powder coating, the surface of the product must be treated to meet the following requirements:

• Removal of industrial grease from machining processes

• Removal of rust from the surface

• Prevention of re-rusting through the application of a zinc phosphate layer

• Formation of a zinc layer to enhance adhesion between the coating and the metal surface

Surface treatment is typically performed by immersing the product in chemical baths, including:

1. Degreasing: Immersion in an NaOH solution to remove grease.

2. Rinsing: Rinsing with clean water.

3. Rust Removal: Immersion in an acid bath (H₂SO₄ or HCl) to eliminate rust.

4. Rinsing: A second clean water rinse.

5. Surface Conditioning: Immersion in a surface-conditioning chemical bath.

6. Phosphating: Immersion in a phosphate chemical bath to create a protective layer.

2. Surface Drying

After chemical treatment, the product is dried before coating.

• Drying Process: Products are placed in drying ovens designed to remove residual moisture, making them ready for powder coating.

• Drying Ovens: Typically cubic, these ovens utilize infrared stoves fueled by gas or electricity. Products are suspended on transport racks for easy handling.

3. Powder Coating

• After drying, the product is placed in a spray booth where the powder is applied and excess powder is recovered.

• Adhesion Mechanism: Powder coating adheres to the metal surface through electrostatic forces.

• Powder Recovery: Excess powder is collected, mixed with new powder, and reused, offering significant cost efficiency.

• The spray booth and recovery system require specialized electrostatic spray equipment and an air supply system, including compressors and dryers.

4. Curing and Finalizing

- After coating, the product is cured in an oven.

• Curing Temperature: 180–200°C

• Curing Time: 15–20 minutes

- Curing ovens use infrared stoves or burners, powered by gas or electricity.

5. Inspection and Packaging

• After curing, the product is cooled, carefully inspected for surface quality, and then packaged.

• Defective products are reprocessed and recoated to ensure quality standards are met.
