Machinery for the Three Stages of Powder Coating
A leading method for high production surface finishing, powder coating is a refined method best known for utilising electrostatic charges to coat components.
However, applying powder is only one part of three stages of production:
- Pre-treatment
- Application
- Curing
Pre-Treatment - Industrial Component Cleaning
For a clean final finish, the component needs to be thoroughly clean of all dust, oils and debris before it can proceed to be powder coated. This can also include inorganic contaminants like rust, mill scale and laser oxide that are side effects of production or parts being refurbished.
The equipment to carry out this process can include wash stations, blast rooms, and dry-off ovens.
Aqueous wash stations such as dip tanks or spray washers would agitate the components in hot water, steam, detergent, and other cleaning solutions to remove the contaminants like grease and oils. This might need to be followed by a dry-off oven to dry the components without leaving any water residue marks.
Solvent cleaners use a different technique to clean parts without using water. Both approaches have their pros and cons but are effective in the right circumstance.
For components that need more TLC than a clean, blast rooms and other shot blasting machinery can be used to refine the profile of the component of rust and scale. Powered by compressed air, small media is shot at the surface to refine the surface of the irregularities. If blasting media is combined with water in a Wet Blast Cabinet the part can be cleaned at the same time as blasting.
Application - Powder Coating Guns
The most widely used method for applying powder to components is Electrostatic Deposition (ESD), featuring an electrostatic spray gun to easily apply the powder coating. The gun is connected to a powder feeder, shooting the powder via an electrostatically charged nozzle. Depending on the gun, this charge can be applied by passing through an ionized electrostatic field in the nozzle or positively charging the particles by rubbing and causing friction against an insulator/conductor inside the gun.
The result of charging the particles causes the stream of powder cloud to adhere evenly to the surface of the component.
With the potential to be a messy process, this would take part in a spray booth to contain the powder, complete with its own extraction system. The extraction system benefits the operator for multiple reasons, including operator safety & comfort.
Another benefit of a Powder Coating Booth fitted with cartridge filters is that it can reduce waste and save on costs for powder. The powder that is unsuccessful in attaching to the component (also known as the overspray) is gathered by the filters during the extraction. These filters are typically located above a recovery bin/hopper, and pulse to release the powder into the bin. This allows the operator to gather and reuse the overspray, also long as they are applying the same finish.
Another popular option for application is fluidized bed powder coating, where the components are dipped in a fluidized bed of powder material. If the bed is pre-heated this allows the component to start curing the powder coating immediately upon application.
Paint Curing - Powder Coating Ovens
For electrostatic deposition applied components that are yet to be cured, the charge of the powder is the only reason the coating stays in place, but once it loses charge it will fall off. Therefore, the curing process is critical to give the coating the durability the finish is known for.
Using an oven made for this process, powder coating ovens are large ovens that heat the air for an even temperature throughout the internal chamber.
The oven would be heated to around 200°C and the component would be placed inside for 10 to 60 minutes. The temperature and duration depends on the size of the component and the specification of the powder.
The result achieved from curing is to melt the powder coating so it bonds together to create a solid and durable film layer over the component.
