At present, all aluminum alloy wheels on the market are cast or forged, and then painted to complete the surface decoration. With the change of aesthetics and individual needs, there are more and more wheel shapes and higher surface decoration requirements. Many wheels appear Two-tone paint. The coloring process of aluminum alloy wheels includes the vacuum sputtering coating method combined with the existing coating process, through covering or arranging the color-changing coating process, the current status of automotive polishing spraying is another color coating, and two-color coating can be achieved through one coating line It improves the metal feeling of the wheel hub, is more conducive to aesthetics and personal needs, saves spraying costs, and reduces spraying pollution. Pretreatment: Aluminum alloy wheels go through pre-degreasing, water washing, pickling, pure water washing, chrome-free conversion, SAM and other processes to complete the process pretreatment steps. The pretreatment of aluminum alloy wheels enters the powder spraying room for powder spraying and drying.
After powder spraying, the aluminum alloy wheels enter the spraying booth for spraying and drying. Tags: alloy wheels.
