How are woodgrain aluminium windows made?

Woodgrain aluminium windows and doors are coated with a variation on the powder coated finish first and the wood effect applied after. The wood effect coating is applied by covering the entire bar length of painted aluminium profile in a special bag that has the desired wood pattern printed on it. The result is an aluminium window that is highly durable, very attractive in appearance and offers a beautiful wood pattern.
The air is sucked out of the bag and hand pressed along the entire profile. The profile is then placed in a sublimation oven that bakes the finish onto the aluminium profile at 200 degrees centigrade. The wood effect “image” is transferred under heat to the powder coated profile. The inks from the bag covering the profile will permeate the powder coated substrate by this advanced “sublimation” process.
At the end of the process the plain painted surface of the aluminium has a wood effect finish. This process does not only extend to wood effects. Granites, marble effects, stone effects and much more are all available under this technology, although not yet available with windows but widely available with other metal products. This sublimation process is already used on other metals, glass, wood, plastics, ceramics and much more.
This provides a strong bond of the wood effect coating not just to the visible faces but the entire aluminium profile. This is the advantage of this process used on aluminium – any surface whether two or three dimensional can be coated with great effect.
The many processes used in achieving this authentic wood finish to aluminium includes surface preparation and cleaning, application of the polyester powder and curing, preparation for sublimation and the oven cured finish.
