What exactly is Powder Coating Equipment?

It is a form of coating equipment which enables in applying powder. Powder coating equipment does not involve solvents in its processes. The coating is completed electrostatically and is also then passed under heat, allowing the powder circulation and form a "skin". It might be a thermoset polymer or possibly a thermoplastic. Generally, it really is employed to provide a hard finish that's harder compared to conventional point that has been formerly used. The key purpose of employing this equipment is for coating metals, such as bicycle parts, household appliances, aluminium planks and more.

Advantages

Few benefits of powder coating are mentioned below:

- Emission Of Volatile Organic Compounds Are Reduced By Coating The Metals 
- It makes Much Thicker Coating As compared with Traditional Liquid Coating 
- It is usually Recycled, Facilitating 100% Reusability In the Substance 
- Produces More reliable Waste As Compared To Traditional Use Of Liquid 
- Lesser Operating Cost Than Liquid Lines

Procedure for Powder Coating

The Powder Coating Equipment operate in following basic processes:

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

Processes And Equipment Of Part Preparation

Prior to the powder coating process eliminating lubrication grease, metal oxides, mud, oil etc are essential. There are several chemical as well as mechanical ways of removing these substances from your metal surface. The technique will depend on the performance element the end product. In spray application process, chemical pre-treatments involve the application of chromates and phosphates. Phosphating and chromating of the substrate occur in multiple stage. Bonding from the powder for the metal involves cleaning inside the pre-treatment process. Sand Blasting is surely an another method of preparing the outer lining ahead of coating. It's used to provide finishing, etching, surface texturing and preparation and degreasing for products made of wood, glass, or plastic. Different powder coating applications can require alternative methods of preparation including abrasive blasting just before coating. The online consumer market typically offers media blasting services coupled with their coating services at additional costs.

Commonly electrostatic gun or corona gun can be used 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 is then sprayed towards the grounded object by mechanical or compressed air spraying equipment. Then it is accelerated on the workpiece through the powerful electrostatic charge. The item will be heated, along with the powder melts in a uniform film, which is then cooled to form a hard coating. To realize more uniform finish preheating may help but problems can also be created as runs due to excess powder.

Tribo gun will be the second form of gun which is often used to spray powder on metal surfaces. The powder is first charged by triboelectric friction and the charged powder particles then adhere to the grounded substrate. It needs a different formulation of powder with respect to corona guns.

Fluidized bed method may also be used for Powder coating. Initially the substrate is heated then it can be dipped into aerated powder-filled bed. Later the powder sticks and melts to the hot object. Most dishwasher racks are coated with this way of [http://people.tribe.net/277d20cf-3a72-43bf-9a86-d19d34328dd5/blog/40a0ab48-bf2a-4644-9180-487bb409f801 powder coating supplies].
