Complete Full Automatic Powder Coating Line Include Pretreatment for High Efficiency

This fully automated powder coating line is designed for high-volume metal parts production and suitable for efficiently processing a large number of small metal carts in batches, and is well-suited for high-volume production, saving a lot of manpower. It includes advanced pretreatment systems, automated spray equipment, and a customizable oven, ensuring consistent and efficient coating quality. Perfect for mass production in industries like automotive, aerospace, and manufacturing.


Spraying Tunnel Pretreatment Tunnel


Continuous pretreatment process in which workpieces are sprayed in different stages. In continuous spray tunnels, minimal amounts of chemicals or water are transferred from one phase to another without sacrificing the efficiency and quality of a perfect conversion layer on the treated metal.

Automatic powder coating pretreatment system is suitable for simple shape and bulk production in fully-automatic line. generally includes 1-5 tunnel stages, such as degrease, conditioning, phosphate, rinse, etc.

Fast Color Change Powder Coating Cyclone Booth / Material could be SS or PP

Fast Color Change Powder Coating Cyclone Booth


The automatic powder coating booth equipment is a key part of high efficiency powder coating line system. 

It is not only setup for simple spraying but also comes with two step powder recovery system that is cyclone and after filter recovery units, to achieve fast color change and realize 98% powder recovery. 

It is the most efficient solution for high powder coating output capacity and clean coating condition.




cyclone

Mono Cyclone Separator

Overspray powders will be transfered to cyclone first. The mono-cyclone is the most powerful choice for overspray collection especially in high speed and high productivity powder coating line.

The cyclone equipment uses centrifugal force and gravity to separate particulates from air stream according to their relative density. Thus, the powders will be effectively collected and transferred to the recycling equipment.

Cartridge Filter Recovery

Cartridge Filter Unit

The secondary stage recovery unit usually includes 9-16 pcs cartridge filters.

As there are also some ultrafine powder particulates with light gravity will not fall down to cyclone bottom, they will be transfered to filter cartridges for final collecting.

Thus vented air stream from the whole system is free of dust particulates, creating a clean working environment.

Self-cleaning Booth Floor

Self-cleaning Booth Floor

The booth floor is designed with air knives and mesh plates specially for self-cleaning.

The cleaning system is controlled by air blasts, which remove the powder accumulated on the booth floor and push it to the extraction and recovery system.

The booth floor always remains clean with just a minimum amount of powder, and increase powder coating recovery.
