The surface treatment process is an indispensable part of the manufacturing industry, which can improve the corrosion resistance, wear resistance, aesthetics and other properties of the parts, thereby improving the quality and service life of the products.
Common parts surface treatment processes include electroplating, spraying, anodizing, sandblasting, polishing, electroplating, painting, QPQ, etc
Passivation
Passivation is the formation of a dense passivation film on the surface of the part to prevent the corrosion reaction between the metal and the external medium. Common passivation methods include chemical passivation and electrochemical passivation.
Polish
Polishing refers to the use of mechanical, chemical or electrochemical action to reduce the surface roughness of the workpiece in order to obtain a bright, flat surface of the surface treatment.
Sand Blast
Sandblasting is a surface treatment method that uses the impact of high-speed sand flow to clean and rough the surface of the workpiece to obtain a certain degree of cleanliness and roughness. It can improve its roughness and adhesion.
Anodizing
Anodizing is the use of metal or alloy electrochemical oxidation and the formation of an oxide film on the surface of the parts of the surface treatment, can prevent parts wear, oxidation can also increase the aesthetic effect. The surface of the part can be realized in different colors. This surface treatment is only suitable for metal parts.
Plating
Galvanizing is a surface treatment method of plating a thin layer of zinc on the surface of the metal, which can prevent metal oxidation, improve wear resistance, corrosion resistance and improve beauty. The surface of the parts can also be plated with copper, nickel, silver and gold. This surface treatment is only suitable for metal parts.
Spray Paint
Spray painting is the surface treatment method of spraying a layer of paint on the surface of a part. The color can be modulated according to the customer's needs, and the surface can achieve matte, bright, metallic luster.
QPQ Salt Bath Composite Treatment Technology
QPQ treatment refers to the black metal parts into two different properties of the salt bath, through various elements into the metal surface to form a composite permeable layer, so as to achieve the purpose of modifying the surface of the parts.
