We provide professional service of designing, manufacturing, assembling, commissioning and training in the coating industry. We have built up many projects in china and abroad. We are able to “right-sizing” your powder coating system.
Power and free conveyor Powder coating Plant
Power and free conveyor powder coating line is special for painting aluminium profiles, compact space required, high output and highht automatical level.
Powder coating line include in Pretreatment, Electrostatic spraying, High temperature curing, Decoration processing
1. Pretreatment
Objective: To get rid of the work-piece surface oil, dirt, rust and in the work-piece surface generating a layer of corrosion resistance and can increase the spraying coating adhesion "phosphating layer".
Main technological steps: In addition to oil, rust removal, phosphating and passivation. The workpiece surface after treatment before not only no oil, rust, dust and the original silver luster surface generating a layer of uniform and the rough is not easy to rust grey phosphating film and can increase the coating layer adhesion.
2. Electrostatic spraying
Objective: Powder coating evenly spray to the surface of the workpiece. The special work (including easy to produce electrostatic shielding position) should be using the high performance electrostatic spray molding machine to complete the painting.
Process steps:
Using electrostatic adsorption principle in the surface of the workpiece evenly spray on a layer of powder coating. Falling powder through the recovery system recovery and sieve used again.
3. High temperature curing
Objective: The workpiece surface of powder coating heating to the specified temperature and heat preservation corresponding time, melting, flow flat, curing.
Process steps: Spraying good workpiece push curing oven, heating to the predetermined temperature (usually 185 degrees) and heat preservation corresponding time (15 minutes). Blow on take out cooling namely get finished.
4. Decoration processing
Objective: Make after electrostatic spraying after the workpiece to achieve a kind of special appearance (all kinds of wood grain, decorative pattern, such as honor).
Process steps: Finish, transfer and treatment process.
We provide professional service of designing, manufacturing, assembling, commissioning and training in the coating industry. We have built up hundreds of turn-key projects in China and abroad.
Technical innovation never ends.
