At present, all aluminum alloy wheels on the market are cast or forged, and then painted to complete the surface decoration. With the changes in aesthetics and individual needs, more and more wheel shapes and higher requirements for surface decoration, many wheels appear Two-tone paint is applied.
The aluminum alloy wheel coloring process includes vacuum sputtering coating method combined with the existing coating process, by covering or arranging the color changing coating process, the current status of automobile polishing spraying is another color coating, and two-color coating can be realized through a coating line. It improves the metal feel of the wheel hub, which is more conducive to appearance and personal needs, saves spraying costs, and reduces spraying pollution.
Pretreatment: The aluminum alloy wheels undergo pre-degreasing, water washing, pickling, pure water washing, chromium-free conversion, SAM and other processes to complete the process pretreatment steps, and the aluminum alloy wheels are pretreated into the powder coating room for powder spray drying.
After powder spraying, the aluminum alloy wheel enters the spraying room for spray drying. After powder spraying, the aluminum alloy wheel enters the spraying room for spray drying.
