How Powder Coating Works
Benefits of Powder Coating
Durability
Powder coating creates a tough, long-lasting finish that resists chipping, scratching, and fading, ensuring parts withstand harsh environments.
Corrosion Resistance
The coating acts as a barrier to moisture and chemicals, protecting metal surfaces from rust and corrosion over time.
Aesthetic Flexibility
With a wide range of colors and finishes available, powder coating enhances the visual appeal of parts to match specific design needs.
Environmentally Friendly
Unlike liquid coatings, powder coating produces minimal waste and does not release harmful solvents, making it a more eco-friendly option.
Design Guidelines for Powder Coating
To ensure efficient spraying, include a hole in the part for hanging it from a wire. The hole should be strategically placed for easy access to all desired surfaces during coating.
Ensure surfaces are properly cleaned and prepped before coating. Oil, dirt, or oxidation can interfere with adhesion and the overall quality of the powder coat.
The spray gun needs access to all surfaces for an even coat. Tight bend radii, small holes, and enclosed areas can cause difficulties. In addition, internal cavities may trap excess powder, leading to an uneven finish. Solution: Add vent holes to facilitate powder escape and ensure a uniform coating.
Powder coating works best on materials like steel, magnesium, and aluminum. Soft, porous, or corroded metals can result in poor adhesion and an uneven finish, making them unsuitable for this process.
