What exactly is Powder Coating Equipment?

It is a form of coating equipment that can help in applying powder. Powder coating equipment doesn't involve solvents rolling around in its processes. The coating is carried out electrostatically and is also then passed under heat, allowing the powder to flow and form a "skin". It may be a thermoset polymer or a thermoplastic. Generally, it is accustomed to provide a hard finish which is harder as opposed to conventional point that was formerly used. The main purpose of using this devices are for coating metals, like bicycle parts, household appliances, aluminium extrusions and others.

Few benefits of powder coating are mentioned below:

- It creates Much Thicker Coating When compared with Traditional Liquid Coating  

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

- Produces Less Hazardous Waste As Compared To Traditional Usage of Liquid  

Technique of Powder Coating

The Powder Coating Equipment work in following basic processes:

- Part Preparation Or The Pre-Treatment  

Before the powder coating process elimination of lubrication grease, metal oxides, mud, oil etc are very important. There are several chemical as well as mechanical methods of removing these substances through the metal surface. The technique depends upon the performance requirement of the end product. In spray application, chemical pre-treatments involve the application of chromates and phosphates. Phosphating and chromating in the substrate appear in multiple stage. Bonding with the powder on the metal involves cleaning in the pre-treatment process. Sand Blasting is surely an yet another way of preparing the outer lining prior to coating. It is accustomed to provide finishing, etching, surface texturing and preparation and degreasing for products manufactured from wood, glass, or plastic. Different powder coating applications can require alternative methods of preparation for example abrasive blasting just before coating. The web consumer market typically offers media blasting services along with their coating services at additional costs.

Commonly electrostatic gun or corona gun is used for using the powder coating to metal objects. Here, lets discuss the significant of electrostatic gun. Negative electric charge is imparted towards the powder. The negatively charged powder will then be sprayed towards the grounded object by mechanical or compressed air spraying equipment. It is then accelerated towards workpiece from the powerful electrostatic charge. The article might be heated, along with the powder melts in a uniform film, and is also then cooled to create a hard coating. To realize more uniform finish preheating could help but problems can be created as runs caused by excess powder.

Tribo gun could be the second form of gun that is utilized to spray powder on metal surfaces. The powder is first charged by triboelectric friction and the charged powder particles then adhere to the grounded substrate. It will take a different formulation of powder when it comes to corona guns.

Fluidized bed method may also be used for Powder coating. To start with the substrate is heated and then it really is dipped into aerated powder-filled bed. Later the powder sticks and melts to the hot object.
