What are the spraying processes for automobile aluminum wheels?
Pretreatment process: The purpose is to form a passivation film on the surface of the wheel to prevent the wheel surface from being corroded.
Powder coating process: There are many options for powder. Generally speaking, if you focus on preventing corrosion, you can use epoxy powder. If you want good weather resistance, you can use polyester powder.
Spraying process: Paints are mainly divided into color paint and varnish. Generally, a car wheel coating line requires more than two spray rooms. Using acrylic paint can avoid color difference. Both varnish and color paint will have a good effect.
