Semi-Automatic Powder Coating Line Design
The semi-automatic powder coating line is specially designed for metal workparts that requires high volume production and uniform coating results while customer has limited factory space and budget to catch up a fully-automatic line. It is ideal for powder coating aluminum profiles, metal frames, furniture, etc.

The semi-automatic powder coating plant mainly includes manually-pulled track system, automatic powder coating booth with conveyor system, automatic powder guns, reciprocators, powder sieving & recycling machine, pass through type curing oven.
Automatic Powder Coating Booth with Coating System
Powder Coating Oven with Track System
How semi-automatic powder coating line works?
1) The operator manually moves the tracks loaded workparts into the powder booth.
2) The workparts will be automatically transported via conveyor system once they enter into the booth
3) There are automatic reciprocating guns at both sidewards of the powder booth for efficient and uniform powder coating
4) After automatic powder coating, the workparts exit out automatically
5) Operator horizontally pulls the workparts to the station in front of the curing oven
6) Manually move the workparts in and out of curing oven.
