Automatic Powder Coating Line for 6m Aluminium Profiles (in Morocco)

This fully-customized automatic powder coating line is specially designed for our Morocco customer for the application of aluminium profiles. The system mainly includes pp plastic powder coating cyclone booth, conveyor system automatic powder guns, reciprocator, powder feed center, curing tunnel

This automatic powder coating line realizes high production capacity, fast color change demands, requires minimum labor and downtime, suitable for customer who has sufficient factory space and budget.

Automatic Powder Coating Line Working Process

Workparts movement is driven through the overhead conveying system. When passing through an automatic spray booth, the workparts get powder spraying by automatic equipment ensures uniform powder film thickness. Afer spraying, the workparts will be automatically transported into a curing tunnel for continuously production. Overspray powders will be transferred from spray booth to the powder feed center for sieving and recycling back to the spray guns.
