Surface Treatment Processing Services

As the professional manufacturer, we would like to provide you KwongTo Surface Treatment Processing Services. During the manufacturing process of mechanical parts, customers usually ask manufacturers to perform surface treatment on metal parts.

Surface treatment is a process applied to the surface of a material to make it better in some way, such as making it more corrosion-resistant or wear-resistant. It is the process of forming an artificial surface layer on the surface of a substrate. And the mechanical, physical and chemical properties of the formed layer are different from those of the substrate. Please note that some raw materials require surface treatment. Because the purpose of surface treatment is to meet the requirements of corrosion resistance, wear resistance, decoration or other special functions of metal parts.

As the professional manufacturer, we would like to provide you Various Color Powder Development Services. Used on ferrous materials such as steel and stainless steel, black oxide forms a layer called magnetite (Fe 3 O 4 ) that provides mild corrosion resistance. It is applied using a high-temperature chemical bath containing an alkaline cleaner, water, caustic soda, and a sealant such as oil to provide a smooth, matte surface. There are also variations of the process that work at lower temperatures, but they offer less wear resistance. Masking is not required for black oxide, as its application does not significantly affect the dimensions of the part.

Various Texture Paint Development Services

As the professional manufacturer, we would like to provide you Various Texture Paint Development Services. Passivation protects steel and stainless steel from corrosion. The process involves a chemical treatment that removes free iron from the surface of the material, resulting in a smooth, shiny surface. It is not a coating so it does not add any thickness to the part, so masking is not required
