Surface treatment for sheet metal and plastics

Question

Accepted Answer

Surface treatment methods for sheet metal and plastics include painting, powder coating, anodizing, and plating.

Painting: Provides a decorative finish and corrosion protection. Can be done manually or through automated processes.
Powder coating: Applied as a dry powder and then cured under heat to form a hard finish. Offers durability and resistance to chipping and scratching.
Anodizing: Creates a protective oxide layer on metal surfaces, improving corrosion resistance and enhancing appearance.
Plating: Involves depositing a thin layer of metal onto the surface of the material for improved aesthetics and corrosion resistance.
