Powder coating is a type of coating that is applied as a dry powder. The powder may be a thermoplastic or a thermoset polymer. It is usually used to create a hard, durable finish on metal surfaces. Powder coating can be done on both ferrous and non-ferrous metals.
There are three types of powder coating systems: batch, continuous, and electrostatic.
Batch powder coating is the most common type of powder coating. The parts to be coated are placed in a batch oven where they are heated until the powder melts and flows onto the surface. The parts are then cooled and the excess powder is removed. You can purchase powder coating ovens via https://www.builtamericanequipment.com/powder-coating-ovens.

Continuous powder coating is done on a conveyor belt. The parts to be coated are placed on the belt and pass through an oven where they are heated until the powder melts and flows onto the surface. The parts are then cooled and the excess powder is removed.
Electrostatic powder coating is done by charging the powder so that it sticks to the surfaces to be coated. The parts to be coated are passed through an electrostatic field where they are charged. The charged powder then sticks to the surface of the parts. The excess powder is then removed and the parts are cooled.
There are two types of powder coating systems: batch and continuous.
Batch powder coating systems are the most common type of system. They typically have a hopper that holds the powder, an applicator gun that sprays the powder, and a curing oven. The parts to be coated are placed in the hopper and the gun is manually triggered to spray the powder onto the parts. The coated parts are then placed in the curing oven to harden the powder.
Continuous powder coating systems are used for high-volume production runs. They have a conveyor belt that moves the parts through each stage of the process. The powder is applied to the parts as they move past the applicator gun and they are cured in an infrared oven or ultraviolet curing chamber.
