Principle: Through the process of friction and grinding, the roughness and unevenness of the surface are removed to obtain a smooth and bright surface.

Adaptation scenario: Suitable for metal and plastic parts, improving appearance quality, increasing glossiness, and eliminating scratches and defects.

Cost comparison: relatively low cost, providing cost-effective surface treatment methods.
Disadvantage: The polishing process may cause slight changes in the size and shape of the parts, especially at the edges and corners. This may have a certain impact on the tolerance of the product.

Principle: By mechanical or chemical methods, longitudinal textures are formed on the surface of the parts to enhance decoration and texture.

Adaptation scenario: Suitable for metal materials such as stainless steel, used in home furnishings, automotive parts, and other fields, creating unique textures and visual effects.

Cost comparison: Provide cost-effective texture processing methods with relatively low costs.

Disadvantage: The Brushing process increases the roughness and texture of the part surface, and is limited by the texture direction, which may have a certain impact on the tolerance of the product. Especially on components that require high-precision fitting or assembly, attention should be paid to the influence of texture direction on tolerances.

Principle: By high-speed spraying of abrasive particles, dirt, oxide layer, and roughness are removed to achieve a uniform and rough surface effect.
Adaptation scenario: Suitable for metal and plastic parts, improving adhesion and providing a better foundation for subsequent painting or electroplating.
Cost comparison: relatively low cost, providing cost-effective and controllable quality surface treatment solutions.​​​​​​​

Disadvantage: Sandblasting can change the surface morphology and roughness of parts, thereby affecting the tolerance of the product to a certain extent. Especially for components that require tight fit or require flatness, attention should be paid to the tolerance changes that sandblasting may introduce.

Principle: Through the electrolysis process, an oxide layer is formed on the metal surface to enhance corrosion resistance and surface hardness.
Adaptation scenario: Commonly used in aluminum alloy parts, providing corrosion resistance, wear resistance, and aesthetics, applied in aviation, automotive, construction and other fields.
Cost comparison: relatively high cost, providing high-quality and durable surface treatment solutions.
Disadvantages: The process is complex and requires strict control. For larger or complex shaped parts, additional processing may be required. Anodizing generally forms an oxide layer on the surface of the part, which may have a certain impact on the tolerance of the product. Especially for components that require precise matching or assembly, attention should be paid to the influence of the thickness of the oxide layer on tolerances.

Principle:  By depositing a metal film on the surface of the part, the appearance, corrosion resistance, and wear resistance are improved.​​​​​​​
Adaptation scenario: Commonly used for metal parts, such as chrome plating, nickel plating, zinc plating, etc., to improve appearance, prevent oxidation, and provide better durability
Cost comparison:The cost varies depending on the electroplating material, thickness, and coating quality, providing a variety of surface treatment options.

Disadvantages:It may cause pollution to the environment, require treatment of wastewater and waste liquid, and coatings may be damaged by mechanical impact or chemical erosion. During the electroplating process, an additional layer of metal film will be added to the surface of the part, which may have a certain impact on the tolerance of the product. Especially on components with high tolerance requirements, attention should be paid to the influence of the thickness of the electroplating layer on the tolerance.

Principle: By spraying fine powder materials, a uniform coating is formed, providing rich colors and effects.
Adaptation scenario: Commonly used for metal and plastic parts, providing durable coatings, applied in fields such as furniture, automobiles, and electronic products.
Cost Comparison:Relatively low cost, providing a variety of color and effect options.

Disadvantages:There may be issues with thinness, unevenness, or bubbles, and certain special shapes or parts with high detail requirements may not be suitable. Powder spraying will form a layer of coating on the surface of the part, which may have a certain impact on the tolerance of the product. Especially for components that require close fit or high flatness, attention should be paid to the influence of coating thickness and uniformity on tolerances.
