What's Powder Coating Equipment?

It is just a type of coating equipment that can help in applying powder. Powder coating equipment does not involve solvents in their processes. The coating is conducted electrostatically and is also then passed under heat, allowing the powder circulation and form a "skin". It could be a thermoset polymer or possibly 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 function of using this products are for coating metals, such as bicycle parts, household appliances, aluminium extrusions and much more.

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

- It Can Be Recycled, Facilitating 100% Reusability From the Substance  

- Produces More secure Waste As compared with Traditional Utilization of Liquid  

Procedure for Powder Coating

The Powder Coating Equipment are employed in following basic processes:

- Part Preparation Or Pre-Treatment  

Before the powder coating process removing lubrication grease, metal oxides, mud, oil etc are crucial. There are numerous chemical in addition to mechanical methods of removing these substances from the metal surface. The process is determined by the performance requirement of the finished product. In spray application, chemical pre-treatments involve the application of chromates and phosphates. Phosphating and chromating from the substrate happen in multiple stage. Bonding from the powder for the metal involves cleaning within the pre-treatment process. Sand Blasting is an another method of preparing the surface ahead of coating. It is used to provide finishing, etching, surface texturing and preparation and degreasing for products made from wood, glass, or plastic. Different powder coating applications can require other methods of preparation including abrasive blasting before 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 significant of electrostatic gun. Negative electric charge is imparted to the powder. The negatively charged powder will then be sprayed towards grounded object by mechanical or compressed air spraying equipment. Then it is accelerated towards the workpiece through the powerful electrostatic charge. The object will then be heated, as well as the powder melts right into a uniform film, which is then cooled to create a hard coating. To realize more uniform finish preheating could help but problems can even be created as runs a result of excess powder.

Tribo gun could be the second sort 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 go through the grounded substrate. It needs a different formulation of powder with regards to corona guns.

Fluidized bed method can 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 to the hot object.
