Aluminum composite cladding is produced by bonding thin aluminum sheets with a plastic core, commonly polyethylene. Composite panels are produced by a continuous lamination process, including preparing and cleaning the aluminum sheets, applying a primer and paint coating, then curing. The plastic core is prepared and bonded to the aluminum layers under heat and pressure. The resulting panels are cut to size, may undergo further processing like punching or bending, and are inspected for quality. A protective film is applied before the panels are packaged and shipped.
