Automobile wheel powder coating line
Key words:
What will happen if the primer-free process is used in the automotive wheel spraying process?
As we all know, the current car wheel spraying process is generally: pretreatment → primer → drying → polishing → primer → color paint → drying → transparent powder → drying. The spray primer is to ensure the flatness of the surface of the substrate and stone-strike resistance, but what problems will occur if the primer-free process is used in the spraying process of automobile wheels?
The fire hazard in the spraying workshop is very high. At present, the commonly used spraying method is to use high-pressure air or a high-voltage electrostatic field to make the paint atomized and adhere to the surface of the car body. Paints generally contain a large amount of flammable, explosive, and volatile diluents with low flash points. The most common is the organic solvent xylene.
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.
The difference between paint spraying and powder coating
I often get the customer's phone number to consult the difference between the painting process and the powder spraying process in the painting production line. Is it better to choose paint spraying and powder spraying? In fact, paint spraying and powder spraying are two completely different coating methods, and the most intuitive difference between paint spraying and powder coating is that one is liquid and the other is solid. Besides, what is the difference? Please let Guangdong Chuangzhi come to introduce you for you!
