Metal materials are used more and more in the existing products, because metal materials can better reflect product quality and highlight brand value. Among many metal materials, aluminum is the first to be adopted by various manufacturers because of its easy processing, good visual effect and rich surface treatment methods. The surface treatment of aluminum profiles is mainly divided: sandblasting (to form a matte pearl silver surface), polishing (to form a mirror surface), drawing (to form a satin-like effect), electroplating (to cover a layer of other metals), spraying (to cover other non-metallic coatings)
The following small series will bring you some relaxing pictures. Follow Ruibao cleaning agent and feel the surface processing technology of aluminum and aluminum alloy in our daily products.
1. Sand blasting (shot peening)

 
The process of cleaning and roughening metal surfaces using the impact of high-speed sand flow. The surface treatment of aluminum parts by 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, increasing the adhesion between it and the coating, prolonging the durability of the coating, and also conducive to the leveling and decoration of the coating. This process is often seen in Apple's various products, as well as being increasingly used by existing TV front shells or mid-frames.
2. Polishing

 
The use of mechanical, chemical or electrochemical methods to reduce the surface roughness of the workpiece, in order to obtain a bright, flat surface processing method. The polishing process is mainly divided into: mechanical polishing, chemical polishing, electrolytic polishing. Aluminum parts can be close to the mirror effect of stainless steel after mechanical polishing and electrolytic polishing, giving people the feeling of high-grade, simple and fashionable future (of course, it is easy to leave fingerprints and take more care). Aluminum cleaning agent, on the choice of RuiSiBo chemical.
3. Wire drawing

 
Metal drawing is a manufacturing process in which aluminum plates are repeatedly scraped out of lines with sandpaper. Wire drawing can be divided into straight wire drawing, random wire drawing, spiral wire drawing and thread drawing. Metal processing WeChat, the content is good, worthy of attention. The metal wire drawing process can clearly show each fine wire mark, so that the fine hair luster appears in the metal matte, and the product has both fashion and technology.

4. High gloss cutting

 
The diamond knife is reinforced by the engraving machine to cut parts on the main shaft of the engraving machine rotating at high speed (generally rotating at 20000 r/min), resulting in a local highlight area on the surface of the product. The brightness of the cutting highlight is affected by the speed of the milling drill bit. The faster the speed of the drill bit, the brighter the cutting highlight. Otherwise, the darker it is and the cutter pattern is easy to produce. Aluminum cleaning agent, RuiSiBo chemical professional choice. High-gloss high-gloss cutting is especially used in mobile phones. For example, iphone5. In recent years, some high-end TV sets have adopted high-gloss milling technology for their metal frames. In addition, anodizing and wire drawing technology make the TV set as a whole full of fashion sense and sharp sense of technology.
5. Anodic oxidation

 
Anodic oxidation refers to the electrochemical oxidation of metals or alloys. Aluminum and its alloys form a layer of oxide film on aluminum products (anodes) under the corresponding electrolyte and specific process conditions due to the action of applied current. Anodic oxidation 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 is currently the most widely used and very successful process.

6. Two-color anodic oxidation

 
Two-color anodizing refers to anodizing on one product and giving different colors to specific areas. Two-color anodic oxidation because the process is complex, the cost is higher; but through the contrast between the two colors, it can better reflect the high-end and unique appearance of the product.
