How is the surface of the sheet metal prototype treated? In order to let you know more about the surface treatment process of sheet metal, we introduce the surface treatment process commonly used in sheet metal prototype. For example: spraying, electroplating, electrophoresis, sandblasting, wire drawing, anodizing, etc. Today we'll start with spraying and electroplating.
Spraying is divided into colored liquid coating spraying and powder spraying. After cleaning or polishing the metal material, paint is sprayed onto the sheet metal surface with a spray gun and gas. After high temperature curing, into a variety of colors of the final coating.
Electroplating is the process of coating certain metal surfaces with a thin layer of other metals or alloys using electrolysis. You can plate one metal onto a single object, or you can plate multiple metals. Many manufacturers choose to layer metals such as copper and nickel to maximize strength and conductivity. Materials commonly used in electroplating include brass, cadmium, chromium, copper, gold, nickel, silver, titanium and so on.
