Automatic Powder Coating Booth System (in Hubei, China)

-  

This automatic powder coating booth system is specially designed for our domesitic Hubei customer for the application of truck parts. The system includes pp plastic powder coating cyclone booth, automatic powder guns, reciprocator, powder feed center.

The customer's most important requirement is the high recovery of powder overspray and a dustless working condition, which means overspraying powders must be continuously collected and transferred back to the system, and there should be minimum amout of powder escape out of the booth or stick on the booth wall. 

Thus we configured with a specially designed automatic powder coating booth made of PP plastic, and work with cyclone recovery system to be the primary role. It is the most efficient solution for high powder recovery rate, as pp plastic material features anti-static, and less powders will stick onto the spray booth or escape outside, which means more powders will be transferred to the powder management center for recycling.

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.
