As an important part of a car, wheels are often corroded by external environments such as mud, water, sand and gravel, so their protective requirements are extremely high.
In order to meet these requirements, thick film cathodic electrophoretic coating and powder spraying are mostly used.
Since the shape of the wheel is relatively simple, the full spray pretreatment process can be used.
The entire process mainly includes parts loading, degreasing, washing, phosphating, drying, powder electrostatic spraying, drying, cooling and other steps.
Parameters such as temperature, pressure and time need to be strictly controlled to ensure the quality and appearance of the wheels.
Among them, phosphating treatment is an important step to improve the coating adhesion, while powder electrostatic spraying is a key link in forming the final appearance of the car wheel.
We are a coating line equipment manufacturer.
