1-PRETREATMENT
Removes oil, dust, and rust from the surface of the aluminium workpiece and creates a corrosion-resistant “phosphating layer” or “chromium layer” on the aluminum surface, which also can increase the adhesion of the coating.

2-POWDER COATING BY ELECTROSTATIC SPRAYING
The powder coating is evenly sprayed onto the surface of the aluminum workpiece. And coating thickness should be about 60-80um, and less than 120um.

3-CURING
The powder coated aluminum workpiece should be placed in a high temperature oven at about 200 ° C for 20 minutes to melt, level, and solidify the powder.

After curing, you will get the powder coated aluminium.
