Color coating method and process of aluminum alloy wheel hub

Aluminum alloys currently on the markethubAll are cast or forged, and then painted to complete the surface decoration. With the change of aesthetics and individual requirements, more and more wheel shapes and higher surface decoration requirements, many wheels appear in two-color paint.

theAluminum alloy wheelsThe color-coating method and process include combining the vacuum sputtering process with the existing coating process, and changing the process of spraying colored paint by covering or finishing. At present, the current situation of spraying another color paint such as automobile polishing, we recognize that through One spraying line can complete two-color spraying, which improves the metallic feeling of the wheel, is more conducive to the appearance and personal needs, saves spraying costs, and reduces pollution caused by spraying.

Pretreatment: Aluminum alloy wheels go through pre-degreasing, degreasing, water washing, water washing, pickling, pure water washing, pure water washing, chromium-free conversion, pure water washing, SAM, pure water washing and other processes to complete the flow pretreatment steps, The pre-treated aluminum alloy wheels enter the powder spraying room for powder spraying and drying.

After powder spraying, aluminum alloy wheels enter the spray booth for spray drying. After powder spraying, aluminum alloy wheels enter the spray booth for spray drying.
