What Is Powder Coating Equipment?

It's a type of coating equipment that can help in applying powder. Powder coating equipment does not require solvents in their processes. The coating is conducted electrostatically and it is then passed under heat, allowing the powder circulation and form a "skin". It might be a thermoset polymer or even a thermoplastic. Generally, it's utilized to give you a hard finish which is harder compared to the conventional point that has been formerly used. The key purpose of using this tools are for coating metals, such as bicycle parts, household appliances, aluminium profiles and many more.

Advantages

Few benefits of powder coating are mentioned below:

- Emission Of Chemical toxins Are Reduced By Coating The Metals 
- It generates Much Thicker Coating As Compared To Traditional Liquid Coating 
- It Can Be Recycled, Facilitating 100% Reusability Of The Substance 
- Produces Less Hazardous Waste In comparison with Traditional Usage of Liquid 
- Lesser Operating Cost Than Liquid Lines

Procedure for Powder Coating

The Powder Coating Equipment are employed in following basic processes:

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

Processes And Equipment Of Part Preparation

Before the powder coating process removal of lubrication grease, metal oxides, mud, oil etc are crucial. There are various chemical along with mechanical ways of removing these substances from your metal surface. The method is dependent upon the performance requirement of the end product. In spray application process, chemical pre-treatments involve the use of chromates and phosphates. Phosphating and chromating in the substrate appear in multiple stage. Bonding in the powder towards the metal involves cleaning within the pre-treatment process. Sand Blasting can be an permanently of preparing the surface before coating. It can be utilized 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 such as abrasive blasting prior to coating. The online consumer market typically offers media blasting services coupled with 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 running of electrostatic gun. Negative electric charge is imparted towards the powder. The negatively charged powder will be sprayed towards the grounded object by mechanical or compressed air spraying equipment. Then it is accelerated towards the workpiece by the powerful electrostatic charge. The item is then heated, and the powder melts in to a uniform film, and is also then cooled to form a hard coating. To attain more uniform finish preheating may help but problems can also be created as runs a result of excess powder.

Tribo gun could be the second form of gun utilized to spray powder on metal surfaces. The powder is first charged by triboelectric friction that charged powder particles then stick to the grounded substrate. It will take an alternative 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 after which it's dipped into aerated powder-filled bed. Later the powder sticks and melts towards the hot object.
