ALUMINIUM PROFILES LACQUERING

We have a vertical lacquering line for aluminium profiles that allows us to lacquer profiles up to 7,5 meters length and an annual capacity of 2.000.000 square meters.

The key to obtain good durability, conservation and lacquered finish lies in carrying out an optimal chemical pre-treatment of the aluminium surface, the use of quality products, especially paint, and finally a correct application and control of the paint in cabin.

LACQUERING ALUMINIUM PROFILES PROCESS

1 The first phase of the lacquering line is the pre-treatment phase whose purpose is to clean the surface of any type of contamination and remove a surface layer from the profile to eliminate the presence of oxides on its surface. In addition, it is also used to prepare the surface in order to achieve a perfect adherence of the paint coating, improving the behavior of the aluminium profile against corrosion. Our line carries out this treatment in seven stages that guarantee a perfect finish and durability of the product.

2 The next phase is the application of the paint coating, which is applied in the form of paint powder with a minimum layer of 60 µm. The paint is electrostatically deposited on the surface of the aluminium profile and is hardened by polymerization in a special oven at around 200 degrees.

3 Finally, all the pertinent controls are carried out to verify that the thickness of the paint is appropriate, both technically and aesthetically. To ensure that the quality of the lacquering is excellent, corrosion resistance tests are periodically carried out on the lacquered aluminium profiles in a acetic saline mist chamber, and in a laboratory accredited under the corresponding regulations.
