What are the aluminum alloy processing technologies?

1.High-light cutting
The diamond knives are reinforced with a fine carving machine to cut the parts on the spindle of the high-speed rotation (typically 20,000 rpm) to produce a local highlight on the surface of the product. The brightness of the cut highlight is affected by the speed of the milling bit. The faster the bit speed, the brighter the cut light, and vice versa, the darker the blade. Metal processing WeChat, the content is good, it is worthy of attention. High-light high-light cutting is especially used in mobile phones, such as iphone5. In recent years, some high-end TV sets have adopted high-gloss milling technology, and the anodizing and wire drawing process makes the TV set full of fashion sense and technology sharpness.
2. Polishing
Using mechanical, chemical or electrochemical methods to reduce the surface roughness of automotive aluminum parts to obtain a bright, flat surface processing method. The polishing process is mainly divided into: mechanical polishing, chemical polishing, and electrolytic polishing. Automotive aluminum parts use mechanical polishing + electrolytic polishing to get close to the stainless steel mirror effect, giving people a high-end simplicity, stylish future feeling (of course, easy to leave fingerprints and more care).
3. Sandblasting is also called shot peening
The process of cleaning and roughening the metal surface by the impact of high velocity sand flow. The aluminum surface treatment of this method can achieve a certain degree of cleanliness and different roughness of the surface of the workpiece, so that the mechanical properties of the surface of the workpiece are improved, thereby improving the fatigue resistance of the workpiece and increasing the interaction between the coating and the coating. The adhesion enhances the durability of the coating and also contributes to the leveling and decoration of the coating. The aluminum alloy process is often seen in various products of Apple, and is increasingly used by existing TV cases or middle frames.
4. Drawing
Metal wire drawing is a manufacturing process in which the aluminum plate is repeatedly scraped out of the line by sandpaper. Drawing can be divided into straight drawing, chaotic drawing, spinning drawing, thread drawing. Metal processing WeChat, the content is good, it is worthy of attention. The metal wire drawing process can clearly show each of the fine silk marks, so that the matte light in the metal matt light, the product has both fashion and technology.
5. Two-color anodizing
Two-color anodization refers to anodization on a product and imparting a different color to a particular area. Two-color anodizing is more expensive due to the complicated process; but the contrast between the two colors can better reflect the high-end and unique appearance of the product.
6. Anodizing
Anodizing refers to the electrochemical oxidation of metals or alloys, and the formation of an oxide film on aluminum products (anodes) by aluminum and its alloys under the corresponding electrolyte and specific process conditions due to the application of current. Anodizing can not only solve the defects of aluminum surface hardness and wear resistance, but also prolong the service life of aluminum and enhance the appearance. It has become an indispensable part of aluminum surface treatment, and it is the most widely used and very successful. Process.
