Wheel-Rim Manual Electrostatic Powder Coating Machine

Brief Introduction:

Powder coating is a type of coating that is applied as a free-flowing, dry powder. The main difference between a conventional liquid paint and a powder coating is that the powder coating does not require a solvent to keep the binder and filler parts in a liquid suspension form. The coating is typically applied electrostatically and is then cured under heat to allow it to flow and form a "skin". The powder may be a thermoplastic or athermosetpolymer. It is usually used to create a hard finish that is tougher than conventional paint. Powder coating is mainly used for coating ofmetals, suchas "whiteware," aluminium extrusions, and automobile and bicycle parts. Newer technologies allow other materials, such as MDF (medium-density fibreboard), to be powder coated using different methods.

The powder coating process involves three basic steps:

1. Part preparation or the pre-treatment
2. The powder application
3. Curing
4. The process of the powder coating is like this: The powder is fluidized in the powder hopper. The injectors transport the powder through the hoses to the guns. The guns spray a powder/air mixture onto the workpieces
