What are the surface treatment methods for industrial aluminum profiles

When it comes to the processing method of industrial aluminum profile profiles, it is necessary to figure out whether it is to change the structure of the aluminum profile or the surface processing technology. Generally speaking, the structure of the aluminum profile can be easily changed by the numerical control lathe [2] (CNC), milling, drilling, and tapping. Threading, stamping, bending and other processes can be deep-processed, especially applied to aluminum housings and some mechanical structural parts. Other surface treatment processes are as follows: 1. The sandblasting process uses the impact of high-speed sand flow to clean and roughen the metal surface. This method can make the surface of the workpiece obtain a certain degree of cleanliness and different roughness, and improve the mechanical properties of the surface of the workpiece, thus improving the fatigue resistance of the workpiece. 2. Polishing uses mechanical, chemical or electrochemical methods to reduce the surface roughness of automotive aluminum parts to obtain a bright and smooth surface. The polishing process is mainly divided into: mechanical polishing, chemical polishing, and electrolytic polishing. 3. Wire-drawing metal wire-drawing is the manufacturing process of repeatedly scraping aluminum plates out of lines with sandpaper. Wire drawing can be divided into straight wire drawing, chaotic wire drawing, swirling wire drawing, and thread drawing. 4. Anodizing Anodizing refers to the electrochemical oxidation of metals. Aluminum and its alloys form an oxide film on the aluminum product (anode) due to the action of the applied current under the corresponding electrolyte and specific process conditions. process. Anodizing can not only solve the defects of aluminum surface hardness and wear resistance, but also prolong the service life of aluminum and enhance its aesthetics. There are also some wood grain processes, electrophoresis processes, and baking paint processes used on architectural aluminum profiles are some of the surface treatment processes that industrial aluminum profile profiles have gradually used in recent years.
