Unlike wet paint, powder coating provides a higher uniformity of colour and thickness consistency. Powder coated castings are cured at high temperatures to ensure tougher, more resilient finishes.

Castings with minor surface flaws may benefit from a powder-coated surface, which can help to conceal and hide cosmetic defects. Powder coating is predominantly used as a decorative cover for castings that require a coloured or high gloss exterior. However, powder coating can also be used to increase the durability of a casting due to its hardened, scratch and corrosion resistant capabilities.

The Process:

  1.  The powder and casting to be coated are oppositely electrostatically charged, making them attracted to  each other.
  2. The desired dry powder is controllably sprayed at the casting surface.
  3. The powder sticks to the surface of the casting (including hard to reach areas) in a very even layer.
  4. The casting is then placed into an oven to cure.

Benefits of Powder Coating:

  • Powder coating is a more environmentally friendly process because the powder contains no solvents, liquid or volatile organic compounds (VOC’s).
  • Specialist powders are available for particular applications, including anti-bacterial coatings for medical applications
  • Provides a decorative finish
  • Increases the hardness of castings
  • Provides castings with a scratch and corrosion resistant coating
  • Can conceal minor surface flaws
  • Unlike wet paint, the powder coating is not wasted on overspray and extraction making it a more effective painting process.
