 Powder coating is typically used to achieve the application of the electrostatic powder to a metal substrate.  This application method uses a spray gun, which applies an electrostatic charge to the powder particles, which are then attracted to the grounded part. 

 After application of the powder coating, the parts enter a curing oven where, with the addition of heat, the coating chemically reacts to produce long molecular chains, resulting in high cross-link density. These molecular chains are very resistant to breakdown.  This type of application is the most common method of applying powders. 

1.The process is simple, mainly due to the improvement of the automatic precision of the main equipment in the production process, and the microcomputer control can be achieved for some major technical parameters, effectively reducing the diffculty of process operation , and greatly reducing the number of auxiliary equipment.

2.The rate of finished products is high. Under normal circumstances, if all measures are implemented properly, the production of defective products can be controlled.

3.The energy consumption is significantly reduced. In the production process of ordinary anodizing and electrophoretic coating, the consumption of water and electricity is considerable, especially in the oxidaiton process. 

4.The pollution to water and atmosphere is reduced. The use of caustic soda sulfuric acid and other liquid organic solvents is no longer used to reduce water and air pollution. It also effectively improves the competitiveness of aluminum profiles and plastic steel profiles as enviromentally friendly products, and accordingly reduces the some production cost.

5.Due to the use of automated assembly line operations, the feeding method and the use of fixtures have been significantly simplified, improving production efficiency and reducing labor intensity.

6.The surface quality requirements for wool have been reduced. The powder coating can completely cover the extrusion lines on the surface of the profile,masking the flaws on the surface of a part, and improving the surface quality of the finished aluminum profiles.

7.Some of the physical properties of the coating are improved compared to other surface applications films, such as hardness and wear resistance, which and effectively extend the service life of the workpieces.
