The aluminium powder coating treatment is a special procedure for protecting the surface of aluminium profiles with a layer of powder applied paint.
First of all, the profiles pass through the pre-treatment tunnel for a cleaning process and obtain a conversion layer for the adhesion of the paint.
At the exit of the pre-treatment tunnel and before passing to the paint booths, they pass through the drying oven to eliminate the remains of water.
In the spray booth, the profiles are sprayed with polyester resin powder.
Once in the polymerization oven, the thermosetting of the resin is carried out, reaching a temperature of 200 ºC.
