Sublimation Process – How to Make Aluminium Look Like Wood

Aluminum That Looks Like Wood

Ceilings, cladding, curtain walls and partitions with aluminium wood finish are often seen in commercial buildings. In the home interior decoration, wood like aluminium doors and windows are very common now, and aluminum furniture with wood grain color has begun into the market. Comparing with the surface of RAL color, the wood finish is more lively, atmospheric, and close to nature.

So how to make aluminum that looks like wood?

There are mainly two methods for making aluminum that looks like wood: SUBLIMATION PROCESS (famous as Decoral), and POWDER ON POWDER PROCESS(famous as Naturall).

SUBLIMATION PROCESS to get a wood finish on aluminium is the most commonly used technology for aluminium industry in China. FONNOV ALUMINIUM, as a professional aluminum extrusion manufacturer, with both wood grain sublimation production lines and powder coating production lines, would like to introduce how to make aluminum that looks like wood through the sublimation process.

At present, most of the wood grain sublimation process is:

aluminum pretreatment ➟ base-color powder coating & curing ➟ wood grain transfer paper covering ➟ curing ➟ paper removal.

»Aluminum Pretreatment:

The aluminum extrusion material must be pretreated before powder coating spraying, so that can improve the adhesion of the aluminum metal surface to the coating.

»The Base-color Powder Coating and Curing:

The powder coating process adopts electrostatic spraying, and the powder coatings that used must be special coatings for wood grain sublimation process. Then to be cured for 20 minutes.

»Wood Grain Transfer Paper Covering:

Wrap the extruded aluminum profile which needs to be transferred with wood grain paper, then vacuumize to be tight.

»Curing:

The wrapped aluminum material is sent to the oven for curing.

»Paper-removal:

After curing, the aluminium profile is pushed out from the oven, and the plastic bag and wood grain paper are pulled out.

This process gives you a clear and realistic wood finish on aluminium. If there are some problems in any step, it may cause the wood grain to be ghosted, unclear, or the surface is not smooth. Therefore, the guidance of the powder coating factory and the wood grain paper/film factory is necessary before production to produce a high-performance aluminum that looks like wood.
