Process flow and operation purpose in aluminium profile machining
Dec 04, 2018

The purpose of pre-treatment in aluminium profile machining is to make the surface of the workpiece to be decontaminated and chemically treated to produce a chrome film, which increases the adhesion and oxidation resistance of the coating and the metal surface, which is beneficial to prolong the service life of the film. Primer coating for aluminium profile machining, as a primer coating for closed substrates, its role is to improve the coating's resistance to penetration, enhance the maintenance of the substrate, stabilize the metal surface layer, and enhance the adhesion of the topcoat to the metal surface. The color uniformity of the top coat can be ensured, and the thickness of the paint layer is generally 5-10 microns.

 The top coat coating in the aluminium profile machining is a key layer of the spray coating. It is to provide the decorative color required for the aluminum material to make the aluminum appearance meet the design requirements, and to maintain the metal surface from the external environment, acid rain and pollution. To prevent UV penetration; greatly enhance the anti-aging ability, the top coat is the thickest layer of paint in the spray, the thickness of the paint is generally 23-30 microns.

The main purpose of the varnish coating in aluminium profile machining is to more effectively enhance the lacquer layer's resistance to external corrosion, maintain the topcoat coating, increase the metallic luster of the topcoat color, and the appearance is more vivid and dazzling. The coating thickness is generally 5-10 microns. The total thickness of the three spray coatings is generally 40-60 microns, which can be further thickened if needed.

Finally, the curing process, generally requires secondary curing, aluminum into the curing oven treatment, curing temperature is generally between 180 ° C -250 ° C, curing time is 15-25 minutes, according to their own coatings, to provide the best temperature and time.
