What exactly is Powder Coating Equipment?

It is just a form of coating equipment that helps in applying powder. Powder coating equipment does not require solvents in their processes. The coating is done electrostatically which is then passed under heat, allowing the powder to circulate and form a "skin". It might be a thermoset polymer or a thermoplastic. Generally, it is used to give a hard finish that's harder compared to the conventional point that has been formerly used. The main intent behind employing this devices are for coating metals, like bicycle parts, household appliances, aluminium planks and much more.

Advantages

Few advantages of powder coating are mentioned below:

- Emission Of Chemical toxins Are Reduced By Coating The Metals 
- It creates Much Thicker Coating When compared with Traditional Liquid Coating 
- It Can Be Recycled, Facilitating 100% Reusability From the Substance 
- Produces Less Hazardous Waste When compared with Traditional Use Of Liquid 
- Lesser Operating Cost Than Liquid Lines

Means of Powder Coating

The Powder Coating Equipment are employed in following basic processes:

- Part Preparation Or Pre-Treatment 
- The Powder Application 
- Curing

Processes And Equipment Of Part Preparation

Before the powder coating process removal of lubrication grease, metal oxides, mud, oil etc are very important. There are various chemical in addition to mechanical types of removing these substances from the metal surface. The technique depends upon the performance feature the end product. In spray application, chemical pre-treatments involve the application of chromates and phosphates. Phosphating and chromating with the substrate appear in multiple stage. Bonding with the powder on the metal involves cleaning from the pre-treatment process. Sand Blasting can be an yet another way of preparing the counter ahead of coating. It's employed to provide finishing, etching, surface texturing and preparation and degreasing for products manufactured from wood, glass, or plastic. Different powder coating applications can require different ways of preparation like abrasive blasting ahead of coating. The web consumer market typically offers media blasting services as well as 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 running of electrostatic gun. Negative electric charge is imparted towards the powder. The negatively charged powder is then sprayed on the grounded object by mechanical or compressed air spraying equipment. It's then accelerated for the workpiece through the powerful electrostatic charge. The object will be heated, and also the powder melts right into a uniform film, and is then cooled to make a hard coating. To realize more uniform finish preheating may help but problems may also be created as runs a result of excess powder.

Tribo gun will be the second kind of gun utilized to spray powder on metal surfaces. The powder is first charged by triboelectric friction that charged powder particles then adhere to the grounded substrate. It takes a different formulation of powder with respect to corona guns.

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