Surface finishing is a technique commonly used in industrial manufacturing processes to improve the properties, appearance and function of the surface of materials. Through surface finishing, the corrosion resistance, wear resistance, electrical conductivity, aesthetics and other properties of the materials can be increased, thus improving the quality and service life of the product. Common parts surface finishing processes include chrome plating, zinc plating, nickel plating, spraying, anodizing, electrophoretic coating, oil spraying, sandblasting, shot peening, polishing, electroplating, electroless plating, hot dip plating, radium engraving, painting, powder spraying, plastic spraying, screen printing. Surface finishing is widely used in metal, plastic, ceramics and other materials, which provides all walks of life with plenty of choices.

Anodizing is the electrochemical oxidation of metals or alloys. The metal or alloy is used as the anode, and the oxide film is formed on its surface by electrolysis. The metal oxide film changes the surface state and performance, such as surface coloring, improving corrosion resistance, enhancing wear resistance and hardness, protecting the metal surface.

The process of using electrolysis to attach a layer of metal film to the surface of metal or other materials. Mainly used for surface finishing for metal products. It can prevent corrosion, improve wear resistance, wear resistance, electrical conductivity, reflectance and improve beauty and so on. The advantage is low cost, high surface finish, the disadvantage is easy to produce bubbles and burrs.

The base plate is coated with primer and topcoat, and each coat is sent to the dust-free oven to bake and finalize, so that the coating forms a solid and beautiful protective film on the surface of the object.

Radium carving, also known as laser engraving or laser marking, is a surface treatment process using optical principles. The laser emits a high-intensity focused laser beam at the focal point. To process the material by oxidizing it. Marking effect is through the evaporation of the surface material to reveal the deep material, or through the light energy to cause the chemical and physical changes of the surface material traces, or through the light energy to burn part of the material, and "engraved" traces, or through the light energy to burn part of the material, showing the graphics and words needed to be engraved.

Passivating is the formation of a dense passivation film on the surface of a metal by chemical or electrochemical methods to improve the corrosion resistance of the metal. Passivation treatment is often used for the surface treatment of stainless steel, copper, aluminum and other metals. The passivation film can effectively prevent the contact between the metal and the corrosive medium, thus protecting the metal from corrosion. The types of passivation are chemical passivation, electroplating passivation, melting passivation, light passivation, electrodeposition passivation and so on. The advantage of passivation is that the product has corrosion resistance, anti-adhesion performance or a certain electromagnetic shielding capability, thereby improving the durability, wear resistance and surface appearance of the material.
