Aluminum can fill-in as a substitution for wood in a wide range of projects. Windows, doors, cupboards, and buildings’ exteriors can all be provided the appearance or look of wood or wood grain aluminum.
So how do extrusion producers make this beautiful wood effect on their aluminum profiles?
There are two methods, utilized successively, to create the wooden look.
Powder Coating – One of the most widely recognized kinds of aluminum finishes.
Sublimation – Used to engrave designs after the process of powder coating.
Subsequent to finishing these procedures, you currently have a substitution for wood that provides you all the advantages of aluminum extrusions.
Below we examine these procedures in further detail.
As referenced above, producers put extrusions through two back to back procedures to make the wood surface – powder coating and sublimation.
Aluminum getting a base coat before curing.
The powder coating procedure can be divided into three stages:
Base Coat – Manufacturers apply a base layer of powder to the aluminum extrusions. The powder is electrostatically charged to upgrade adhesion.
Curing – Aluminum profiles are set in a restoring oven. Regularly they are kept in the oven for around ten minutes, at temperatures of about 200 degrees Celsius.
Cool Down – The profiles are expelled from the curing oven and permitted to chill off. When they’re completely cooled, it’s the ideal time for the sublimation procedure.
The sublimation procedure has four essential steps:
Film Wrapping – A film with the decorative design (For this situation, wood grain) is folded over the aluminum profile.
Air Removal – All air is expelled from the space between the film and the profile. Along these lines, the film remains firm against the coated aluminum.
Curing – Wrapped extrusions are set into a curing oven. As they heat up, the wood grain design gets moved from the film to the aluminum.
Cool Off – Extrusions are pulled out of the grill, and the film is evacuated. Now, the pattern has been completely transferred to the aluminum profiles. They are permitted to cool down.
After powder coating and sublimation, the extrusions would now be ready to ship.
Similar to wood, there is a simplified process called bright dip anodizing. Anodizing includes inundating the aluminum in an acid electrolyte shower with a cathode, a defensive oxide layer shapes on the outside of the part being treated by passing an electrical flow through the bath.
Aluminum extrusions can be planned as complicated interlocking shapes. The wood impact gives them a decent, natural look. Now, you can plan items that have a pleasant, organic look and all the advantages of aluminum.
