Profile: SanYong Aluminum Surface Finishing Factory provides various finishing processes and services. We specialize in services such as anodizing, hard-coat anodizing, electro-polishing, passivation, chromate conversion, selective masking, abrasive blasting, chemical plating and electrophoretic painting. We serve industrial, commercial and aerospace/defense companies. Our anodizing service is an electrochemical process that causes aluminum oxide to form a desired conversion on the surface of aluminum and aluminum alloys. It offers corrosion resistance for stainless steel material and surface hardness of 15-300HV. It increases the scratch resistance of the material. Our hardcoat anodizing forms a thick aluminum oxide coating. This layer becomes an integral part of the metal. The precise application of the hardcoat process provides a uniform surface, even to complex parts, while significantly improving the properties of aluminum. Our electroplating process is primarily used for depositing a layer of material to bestow a desired property to a surface that otherwise lacks that property.
