Hardware Surface Treatment Processes Primarily Include The Following

Hardware surface treatment processes primarily include the following:

Wire drawing

A surface treatment method that creates decorative lines on the surface of a workpiece by grinding a product. Wire drawing patterns can be categorized as straight, random, wavy, or spiral.

Sandblasting

A process that uses compressed air to create a high-speed jet of material, which is then applied to the surface of the workpiece. This process alters the appearance or shape of the workpiece, achieving a certain degree of cleanliness and varying degrees of roughness.

Polishing

The surface of a workpiece is modified using flexible polishing tools and abrasive particles or other polishing media.

Electroplating

A process that deposits a metallic film on the surface of a metal through electrolysis, providing corrosion protection, improving weldability, conductivity, and aesthetics.

Anodizing

Primarily used for aluminum, anodizing uses electrochemical principles to create an aluminum oxide film on the surface of aluminum and aluminum alloys. This film possesses special properties such as protective, decorative, insulating, and wear-resistant properties. Electrophoresis

Used on stainless steel, aluminum alloys, and other materials, it can impart a variety of colors while maintaining a metallic luster, enhancing surface properties and providing excellent corrosion resistance.

Micro-arc oxidation

The process of applying a high voltage to an electrolyte solution (typically a weakly alkaline solution) creates a ceramicized surface film. This process is the synergistic effect of physical discharge and electrochemical oxidation.

PVD vacuum plating

Physical vapor deposition is a technique that primarily utilizes physical processes to deposit thin films.

Powder coating: Powder coating is applied to the surface of a workpiece using a powder sprayer (electrostatic sprayer). Under the influence of static electricity, the powder is evenly adsorbed onto the surface, forming a powdery coating. This powder coating is then baked at high temperatures for leveling and curing, resulting in a final coating with varying effects (e.g., different types of powder coating). A wide range of colors are available, with both high-gloss and matte finishes available. It is also cost-effective and suitable for architectural furniture, computer enclosures, and other products, with excellent defect concealment capabilities.

These are the main processes for hardware surface treatment. These processes can be selected and combined to achieve the optimal treatment effect based on different needs and objectives.
