Let's take a look at the aspects of aluminum alloy processing technology:
1. Sandblasting: refers to the process of cleaning and roughening the metal surface by the impact of high-speed sand flow. In order to obtain a certain degree of cleanliness and different roughness of the workpiece surface, aluminum parts are generally surface treated in this way, and the mechanical properties of the workpiece surface can also be improved, thereby improving the fatigue resistance of the workpiece, the workpiece and the coating. The adhesion between them is greatly increased, the durability of the coating is prolonged, and it plays a good role in the leveling and decoration of the coating. This aluminum alloy process is often found in various Apple products, and is increasingly used by existing TV front covers or middle frames.
2. Polishing: reduce the surface roughness of automotive aluminum parts by mechanical, chemical or electrochemical methods, so as to obtain a bright and smooth surface processing method. The polishing process mainly includes mechanical polishing, chemical polishing and electrolytic polishing. After mechanical polishing + electrolytic polishing, the aluminum parts of the car can be close to the mirror effect of stainless steel, giving a high-end, simple and stylish future feeling (of course, it is easy to leave fingerprints and needs more care).
3. Wire drawing: Metal wire drawing is the manufacturing process of repeatedly scraping the lines of aluminum sheets with sandpaper. The wire drawing patterns can be divided into straight lines, random figures, spiral figures and thread figures. The metal wire drawing process can clearly show every tiny silk screen, making the metal matte shine with slender hair. The product has a sense of fashion and technology.
4. High gloss cutting: The engraving machine strengthens the diamond cutter on the high-speed rotating shaft of the engraving machine (usually 20000RPM) to cut the parts, and produces local bright areas on the surface of the product. The brightness of the cutting highlights is affected by the cutter speed. The faster the drilling speed, the brighter the cut highlights. Otherwise, the darker the highlights, the easier it is to produce knife marks. Metal processing WeChat content is good, worthy of attention.
5. Anodizing: Anodizing refers to the electrochemical oxidation process of aluminum and its alloys in the corresponding electrolyte and specific process conditions, under the action of external current, to form an oxide film on aluminum products (anode). Anodizing can not only solve the defects of aluminum surface hardness and wear resistance, but also enhance the aesthetics of aluminum and prolong the service life of aluminum. It is a process that is often used in aluminum surface treatment and is currently widely used. , successful craftsmanship.
