Introduction of electrostatic powder coating oven
Powder curing oven - whether electrical, gas or diesel fired. Whether batch type or conveyorised tunnel type.
Commonly in a range between 150-250 degrees Celsius. The part is heated by the hot air in the oven and it in turn conducts heat into the coating.
Convection cure time may be as short as 10 minutes or as long as 30 minutes, depending on the mass of the substrate and the cure requirements of the powder.
Electrostatic powder coating for main equipment area:
1. Spray gun machine (including high voltage generator,spray gun, hopper, barrel,control system)
2. Spray booth
3. Recycling equipment
4. Conveyor system(including chain,track, hanger, and drive motor)
5. Curing oven(including automatic temperature control device and ventilation device)
6. Air compressor (including oil water separation system)

Why should I choose powder coating over wet spray painting?
Powder coating is just "flat-out" superior to wet spray in so many ways. If your part is capable of being powder coated, their is really no reason why you would be compelled to choose otherwise. It's generally less expensive to powder coat a part once than have it painted several times during its life.
Powder coating is not subject to the extra time it takes to set up and break down from wet spray paint. The chemicals used in wet spray painting have to evaporate which can take up to weeks before a complete "cure" is attained. Powder coated parts are "cured" as soon as the part cools down. Further, the thermal bonding process used in powder coating makes for a much more durable finish than wet spray paint. Powder coating is also more environmentally friendly than wet spray painting because it does not involve the potentially harmful chemicals used in a wet spray painting.
As mentioned above, wet spray painting involves the use of chemicals that can be potentially hazardous to people and the environment if not dealt with properly. Powder coating uses an air gun to blow away misapplied powder rather than resort to the chemical thinners that wet spray paints require to clean up, or fix, application errors.
Powder coating offers a wider variety of colors and textures. The powder can be engineered to wrinkle or create veins of different colors throughout the coating when baked. Wet spray paint is more limited in what it can produce. Yet the possibilities with powder coatings are endless.
And finally, powder coating is more durable and weather resistant than wet spray paint could ever be. When we bake out the parts, the powder melts, forming a seamless bond around the parts. This bonding process creates a virtually unbreakable sheet of protection upon the surface of the parts.
