company news about Electrostatic spraying equipment for automobile wheels

Automobile wheel spray molding line equipment: Iron wheels can be used in iron, zinc or zinc calcium phosphating before painting, the shape of the wheel is relatively simple, can take the whole spray line pretreatment process.

The wheel is often subjected to intense erosion by mud and water, so the protective performance of the wheel is relatively high. Because the wheels are exposed to both sides of the car, the appearance of the wheel coating has higher requirements for high-end cars such as cars, and the protection requirements are higher. Therefore, the car wheels are mostly coated with thick film cathodic electrophoretic coating, and some use powder spraying. The truck generally uses a primary cathodic electrophoretic primer or spray bottom and top paint; Aluminum alloy wheels need to be chemically oxidized and then sprayed with metal flash paint. The iron wheel can be phosphating with iron, zinc or zinc calcium before coating. The shape of the wheel is relatively simple, and the whole spray pretreatment process can be adopted.
