It's a sort of coating equipment that helps in applying powder. Powder coating equipment does not involve solvents in the processes. The coating is carried out electrostatically which is then passed under heat, allowing the powder to flow and form a "skin". It can be a thermoset polymer or a thermoplastic. Generally, it can be used to give you a hard finish that's harder than the conventional point that was formerly used. The key function of applying this devices are for coating metals, such as bicycle parts, household appliances, aluminium profiles and others.

Few advantages of powder coating are mentioned below:

- It makes Much Thicker Coating In comparison with Traditional Liquid Coating  

- Produces More secure Waste When compared with Traditional Using Liquid  

Procedure for Powder Coating

The Powder Coating Equipment operate in following basic processes:

Before the powder coating process removal of lubrication grease, metal oxides, mud, oil etc are necessary. There are various chemical along with mechanical methods of removing these substances through the metal surface. The process is dependent upon the performance requirement of the end product. In spray application process, chemical pre-treatments involve the application of chromates and phosphates. Phosphating and chromating with the substrate appear in multiple stage. Bonding of the powder to the metal involves cleaning within the pre-treatment process. Sand Blasting is definitely an another way of preparing the outer lining ahead of coating. It's used to provide finishing, etching, surface texturing and preparation and degreasing for products made of wood, glass, or plastic. Different powder coating applications can require different ways of preparation like abrasive blasting ahead of coating. The net consumer market typically offers media blasting services as well as their coating services at additional costs.

Commonly electrostatic gun or corona gun is used for applying the powder coating to metal objects. Here, lets discuss the running of electrostatic gun. Negative electric charge is imparted on the powder. The negatively charged powder will then be sprayed on the grounded object by mechanical or compressed air spraying equipment. This will make it accelerated on the workpiece with the powerful electrostatic charge. The thing will be heated, as well as the powder melts in a uniform film, and it is then cooled produce a hard coating. To realize more uniform finish preheating could help but problems can even be created as runs brought on by excess powder.

Tribo gun is the second type of gun which is used to spray powder on metal surfaces. The powder is first charged by triboelectric friction which charged powder particles then go through the grounded substrate. It takes an alternative formulation of powder when it comes to corona guns.

Fluidized bed method doubles for Powder coating. Initially the substrate is heated then it is dipped into aerated powder-filled bed. Later the powder sticks and melts to the hot object.
