This is a type of coating equipment that helps in applying powder. Powder coating equipment does not involve solvents rolling around in its processes. The coating is carried out electrostatically and is then passed under heat, allowing the powder circulate and form a "skin". It might be a thermoset polymer or a thermoplastic. Generally, it really is accustomed to give a hard finish that is harder compared to conventional point that was formerly used. The principle intent behind employing this tools are for coating metals, like bicycle parts, household appliances, aluminium extrusions and much more.

- It creates Much Thicker Coating In comparison with Traditional Liquid Coating  

- Produces Better Waste As Compared To Traditional Usage of Liquid  

The Powder Coating Equipment are employed in following basic processes:

- Part Preparation Or Pre-Treatment  

Prior to the powder coating process eliminating lubrication grease, metal oxides, mud, oil etc are very important. There are various chemical along with mechanical types of removing these substances in the metal surface. The technique depends upon the performance feature the end product. In spray application process, chemical pre-treatments involve the application of chromates and phosphates. Phosphating and chromating from the substrate exist in multiple stage. Bonding with the powder to the metal involves cleaning in the pre-treatment process. Sand Blasting can be an yet another way of preparing the counter before coating. It can be 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 like abrasive blasting before coating. The net consumer market typically offers media blasting services along with their coating services at additional costs.

Commonly electrostatic gun or corona gun is utilized for utilizing the powder coating to metal objects. Here, lets discuss the significant of electrostatic gun. Negative electric charge is imparted for the powder. The negatively charged powder will then be sprayed for the grounded object by mechanical or compressed air spraying equipment. This will make it accelerated towards workpiece through the powerful electrostatic charge. The thing might be heated, along with the powder melts in a uniform film, and is then cooled to form a hard coating. To realize more uniform finish preheating may help but problems can be created as runs a result of excess powder.

Tribo gun may be the second form of gun which is used 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 another formulation of powder when it comes to corona guns.

Fluidized bed method may also be used for Powder coating. At first the substrate is heated then it really is dipped into aerated powder-filled bed. Later the powder sticks and melts for the hot object. Most dishwasher racks are coated using this way of [http://www.migente.com/your_page/blog/view_posting.html?pid=5377910&profile_id=8536291&profile_name=clementjsfs&user_id=8536291&username=clementjsfs powder coating equipment].
