Powder Application Methods

The method chosen to apply powder coatings varies depending upon the specific part, process, and specifications. There are a number of methods available for applying powder coatings. 
Factors to consider in coating methods:
  • Film thickness requirements
  • Means of conveying the part through the coating process, line speed, and racking configurations
  • Part configuration/size/thickness
  • Powder coating chemistry
  • Product performance characteristics
  • Number of colors used
  • Means of applying the powder – automatically, manually, or combination
  • Plant space and capabilities of powder coating equipment

Powder coating application methods range from simple dipping into a fluidized bed of the powder to a more complex electrostatic spray process.  Each process has advantages for specific applications.

Most commonly used methods include:
  • Fluidized bed
  • Electrostatic fluidized bed
  • Electrostatic spray
  • Other various methods including flocking, electrostatic disc, flame spray etc.
