As the project a wide range of machinery, specifications, machine weight, large parts, the general approach to spray paint. Spray tool air spray gun, airless spray gun, air-assisted forklift jacks spray gun and portable electrostatic spray gun. Low air spray gun efficiency (about 30%), high-pressure airless spray gun paint waste, both common feature is more serious environmental pollution, it has been replaced by air-assisted spray gun and portable electrostatic spray gun and being. As the world's first mechanical engineering company --- Caterpillar (CAT) company on the use of air-assisted spray gun on the hood, such as sheet metal cover portable electrostatic spray gun is used. Engineering machinery coating equipment generally use more advanced water rotary spray booth. Small parts can also be used with or without a pump spray booth curtain spray booth, the former has advanced performance, the latter affordable, convenient and practical. Due to heavy construction machinery and parts machine, heat capacity, so its anti-rust coating drying, the general uniform baking hot air convection Rider Pallet Truck drying method. Heat can be adapted to local conditions, the choice of steam, electricity, light diesel oil, natural gas and liquefied petroleum gas.
