What are the spraying processes for automotive aluminum alloy wheels?


In the aluminum wheel manufacturing process, the spraying process is a very critical link. By strengthening the quality control of the spraying process, it is not only helpful to make the appearance of the aluminum wheel more beautiful and generous, but more importantly, to avoid pollutants in the driving environment of the car. The erosion of the wheel hub prolongs the life of the wheel. Among them, the spraying process includes powder spraying process and painting process.

Process of spraying production line for automobile aluminum alloy wheel hub


Automobile wheels can be divided into steel wheels and aluminum alloy wheels in terms of material. As people’s requirements for automobiles are getting higher and higher, as well as the market development trend, many cars currently generally use aluminum alloy wheels, because compared to steel wheels, aluminum alloy wheels have Lighter weight, low inertial resistance, high manufacturing accuracy, small deformation during high-speed rotation, and low inertial resistance, which are beneficial to improve the straight-line driving performance of the car, reduce the rolling resistance of the tire, and reduce fuel consumption. However, aluminum alloy wheels with better performance have higher requirements for spraying. Next, I will introduce the production line of automotive aluminum alloy wheels.
