What Is the Process for Powder Coating Aluminum Extrusions?

The process of powder coating consists of spraying finely ground resin and pigment on the aluminum surface. The entire step-by-step process of powder coating aluminum extrusions includes:

  1. Pre-treat the surface of the aluminum extrusions: Pre-treating the surface ensures that you remove all debris, dust and other substances from the aluminum surface. A clean surface allows the powder coating to evenly coat the entire aluminum extrusions and prevent flaking.
  2. Apply powder to the aluminum surface: The technician will use an electrostatic spray gun to apply the powder coating. The aluminum extrusions are electrically grounded, which allows the charged particles to stick to the aluminum surface.
  3. Heat the aluminum extrusion: The technician heats the extrusions in a curing oven to melt the powder coating evenly. 
  4. Cool the aluminum extrusion to harden coating: Once the powder coating melts over the entire surface, the technician will remove the extrusion from the curing oven to cool and harden. The surface will be solid and smooth with a quality powder coat finish.
