Lamination is a physical process, in which a layer of film and a layer of aluminum plate are pressed together under high temperature and high pressure; roll coating uses international standard aluminum materials starting with 3 as the base material, and is pressed together through a three-coating and three-baking roll coating process; anodizing is to use metal or alloy parts as anodes, and use electrolysis to form an oxide film on its surface.
