Powder Coating Machine Manufacturer
Our powder coating machine or powder coating paint machine is our own production, manufactured in our facility in Turkey. The powder paint machine is made in 2 different versions, depending on their usage
- Tribo powder coating gun
- Corona powder coating gun
Tribo Powder Coating Equipment
Tribo powder coating equipment doesn’t have electrical charging parts in them (also called as cascades) and they charge the powder coating powder by friction of the powder to the inside pipes of the gun. This friction charges the particle because of this, the barrels of the tribo guns are longer in comparison to the corona guns.
In the tribo equipment, the operator can’t change the charging values such as voltage and current but can only change the air volume. As Tribo guns have less electronic parts, they are more resistant to breakdowns and have longer service lives.
Corona Powder Coating Equipment
Corona is the type of powder coating equipment where the charging is carried out by the cascade in the powder spray gun. The cascade is a voltage-increasing electronic component that applies high voltage and low current onto the passing powder particles to let them stick on the parts they are flying to.
The cascades are voltage-increasing parts of a powder coating gun and is located on the plastic pipe where the powder coating particles are passing.
As the other parts of the powder coating machines, we also manufacture our own powder coating guns and cascades inside. Our guns have 2 years of guarantee.
