Scratches on the surface of aluminum plates are more likely to occur in the process of aluminum plate processing. It is often caused by improper processing and treatment, which causes the surface to be damaged, which seriously affects the aesthetics of the aluminum plate. तथापि, the scratches have already appeared. The following describes the surface scratch treatment of the aluminum plate. method.
The surface scratches of aluminum plates can be treated.
