Aluminum profile coating process

Similar to other metal coating lines, proper pretreatment is crucial here. From the industry, there’re different coating techniques being used: Powder coating and liquid coating. There’s big difference for workflows. Let’s firstly see traditional liquid coating.

Loading -> Pretreatment(rinsing, degreasing, phosphating) -> Pre-heating -> base coat painting -> leveling -> drying -> Top coat painting -> leveling -> leveling -> drying -> varnish painting -> leveling -> drying -> unloading

As we see, there’re lots of sections for this coating line setup. However, it’s different for powder coating. Powder coating for aluminum profile is followed by this workflow:

Loading -> Pretreatment(rinsing, degreasing, phosphating) -> Pre-heating -> powder coating -> Curing -> unloading

The powder coating solution simplified the entire process and can bring us the same level quality. The powder coating solution is applied by most modern manufacturers for low cost investment and high efficiency.

Aluminum profile coating line structures include: water tank, hanging conveyor, Spray booth, curing oven, electric control box.

Unlike other products, aluminum profiless come with long shapes and sometimes with big size(like boards). Thus, the spray booth and curing oven is pretty big comparing to any other coating line setup. Especially for hanging conveyor, it can be as high as 6 meters for smooth operation.
