What Is Powder Coating Equipment?

This is a type of coating equipment which enables in applying powder. Powder coating equipment does not require solvents rolling around in its processes. The coating is done electrostatically which is then passed under heat, allowing the powder to flow and form a "skin". It might be a thermoset polymer or a thermoplastic. Generally, it's accustomed to give a hard finish which can be harder compared to conventional point which was formerly used. The principle purpose of employing this devices are for coating metals, including bicycle parts, household appliances, aluminium planks and many more.

Advantages

Few features of powder coating are mentioned below:

- Emission Of Chemical toxins Are Reduced By Coating The Metals 
- It creates Much Thicker Coating As Compared To Traditional Liquid Coating 
- It is usually Recycled, Facilitating 100% Reusability In the Substance 
- Produces More secure Waste In comparison with Traditional Usage of Liquid 
- Lesser Operating Cost Than Liquid Lines

Process 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

Ahead of the powder coating process removing lubrication grease, metal oxides, mud, oil etc are necessary. There are several chemical along with mechanical methods of removing these substances through the metal surface. The process is dependent upon the performance element the finished product. In spray application, chemical pre-treatments involve the use of chromates and phosphates. Phosphating and chromating with the substrate occur in multiple stage. Bonding of the powder on the metal involves cleaning inside the pre-treatment process. Sand Blasting is an another way of preparing the outer lining ahead of coating. It is employed 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 prior to coating. The net consumer market typically offers media blasting services in conjunction 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 running of electrostatic gun. Negative electric charge is imparted to the powder. The negatively charged powder is then sprayed for the grounded object by mechanical or compressed air spraying equipment. It is then accelerated for the workpiece with the powerful electrostatic charge. The article is then heated, and also the powder melts in to a uniform film, and it is then cooled to form a hard coating. To accomplish more uniform finish preheating could help but problems can also be created as runs due to excess powder.

Tribo gun is the second form 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 takes another formulation of powder when it comes to corona guns.

Fluidized bed method can also be used for Powder coating. At first the substrate is heated and after that it can be dipped into aerated powder-filled bed. Later the powder sticks and melts on the hot object. Most dishwasher racks are coated with this particular technique of [http://wallinside.com/post-33311479-thoughts-on-swift-systems-of-powder-coating-supplies.html powder coating supplies].
