What Is Powder Coating Equipment?

It is a kind of coating equipment that helps in applying powder. Powder coating equipment does not require solvents in its processes. The coating is carried out electrostatically and it is then passed under heat, allowing the powder circulate and form a "skin". It may be a thermoset polymer or even a thermoplastic. Generally, it can be utilized to offer a hard finish which can be harder than the conventional point that has been formerly used. The primary purpose of using this equipment is for coating metals, including bicycle parts, household appliances, aluminium planks and many more.

Advantages

Few attributes of powder coating are mentioned below:

- Emission Of Volatile Organic Compounds Are Reduced By Coating The Metals 
- It generates Much Thicker Coating As Compared To Traditional Liquid Coating 
- It Can Be Recycled, Facilitating 100% Reusability From the Substance 
- Produces Less Hazardous Waste As Compared To Traditional Usage of Liquid 
- Lesser Operating Cost Than Liquid Lines

Means of Powder Coating

The Powder Coating Equipment be employed in following basic processes:

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

Processes And Equipment Of Part Preparation

Prior to powder coating process removal of lubrication grease, metal oxides, mud, oil etc are very important. There are various chemical as well as mechanical types of removing these substances through the metal surface. The strategy depends upon the performance feature the finished product. In spray application, chemical pre-treatments involve the application of chromates and phosphates. Phosphating and chromating from the substrate occur in multiple stage. Bonding in the powder for the metal involves cleaning within the pre-treatment process. Sand Blasting is surely an permanently of preparing the outer lining prior to coating. It's 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 including abrasive blasting just before coating. The internet consumer market typically offers media blasting services coupled with their coating services at additional costs.

Commonly electrostatic gun or corona gun is used for utilizing the powder coating to metal objects. Here, lets discuss the functional 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 is then accelerated for the workpiece with the powerful electrostatic charge. The article will then be heated, and the powder melts in a uniform film, which is then cooled to create a hard coating. To attain more uniform finish preheating can help you but problems can even be created as runs caused by excess powder.

Tribo gun will be the second type of gun that is utilized to spray powder on metal surfaces. The powder is first charged by triboelectric friction that charged powder particles then follow the grounded substrate. It requires another formulation of powder regarding corona guns.

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