What exactly is Powder Coating Equipment?

It's a sort of coating equipment that helps in applying powder. Powder coating equipment doesn't involve solvents in their processes. The coating is completed electrostatically and is then passed under heat, allowing the powder to circulate and form a "skin". It might be a thermoset polymer or possibly a thermoplastic. Generally, it's used to offer a hard finish that is harder compared to the conventional point which has been formerly used. The principle function of by using this equipment is for coating metals, such as bicycle parts, household appliances, aluminium extrusions and more.

Few benefits of powder coating are mentioned below:

- It Produces Much Thicker Coating As compared with Traditional Liquid Coating  

- It may be Recycled, Facilitating 100% Reusability From the Substance  

- Produces More reliable Waste As Compared To Traditional Usage of Liquid  

The Powder Coating Equipment work in following basic processes:

- Part Preparation Or perhaps the Pre-Treatment  

Ahead of the powder coating process eliminating lubrication grease, metal oxides, mud, oil etc are necessary. There are many chemical along with mechanical methods of removing these substances from your metal surface. The process is determined by the performance feature the end product. In spray application process, chemical pre-treatments involve the usage of chromates and phosphates. Phosphating and chromating of the substrate happen in multiple stage. Bonding with the powder on the metal involves cleaning inside the pre-treatment process. Sand Blasting can be an yet another way of preparing the top ahead of coating. It's employed to provide finishing, etching, surface texturing and preparation and degreasing for products made from wood, glass, or plastic. Different powder coating applications can require various ways of preparation such as abrasive blasting just before coating. The web consumer market typically offers media blasting services in conjunction with their coating services at additional costs.

Commonly electrostatic gun or corona gun is employed for utilizing the powder coating to metal objects. Here, lets discuss the working of electrostatic gun. Negative electric charge is imparted towards the powder. The negatively charged powder is then sprayed for the grounded object by mechanical or compressed air spraying equipment. It is then accelerated towards the workpiece through the powerful electrostatic charge. The object will be heated, and the powder melts in a uniform film, and is also then cooled to make a hard coating. To achieve more uniform finish preheating could help but problems can be created as runs a result of excess powder.

Tribo gun may be the second kind of gun which is used to spray powder on metal surfaces. The powder is first charged by triboelectric friction which charged powder particles then follow the grounded substrate. It requires some other formulation of powder with regards to corona guns.

Fluidized bed method could also be used for Powder coating. In the beginning the substrate is heated and then it can be dipped into aerated powder-filled bed. Later the powder sticks and melts towards the hot object.
