shan Quanshun Aluminum Co., LTD. Is an integrated enterprise integrating aluminum extrusion, aluminum alloy processing and automobile aluminum alloy parts development. This article small make up for everyone to introduce the aluminum alloy is how to process.
1. Sand blasting is also called shot peening
The process of cleaning and roughening metal surfaces using the impact of high speed sand flow. This method of aluminum surface treatment can make the workpiece surface obtain a certain degree of cleanliness and different roughness, so as to improve the mechanical properties of the workpiece surface, so as to improve the fatigue resistance of the workpiece, increase the adhesion between it and the coating, prolong the durability of the coating film, but also conducive to paint flow and decoration. The aluminum alloy process is often seen in apple's various products, as well as the existing TV shell or frame is increasingly used.
2. The polishing
Using mechanical, chemical or electrochemical methods to reduce the surface roughness of automobile aluminum parts, so as to obtain a bright, smooth surface processing method. Polishing process is mainly divided into: mechanical polishing, chemical polishing, electrochemical polishing. Auto aluminum parts using mechanical polishing + electrolytic polishing can be close to the stainless steel mirror effect, giving people a high-end simple, stylish future feeling (of course easy to leave fingerprints but also more care).
3. The drawing
Metal wire drawing is the manufacturing process of repeatedly using sandpaper to scrape the aluminum plate out of the wire. Drawing wire can be divided into straight wire drawing, random wire drawing, spiral wire drawing, thread drawing. Metal processing WeChat, the content is good, worthy of attention. Metal wiredrawing process can clearly show every tiny silk mark, so that the metal matte in the hair with a fine luster, both fashion and technology sense.
4. High gloss cutting
The diamond cutter is reinforced by the engraving machine to cut the parts on the spindle of the engraving machine with high speed (the general speed is 20,000 RPM/min) to produce local highlighting areas on the product surface. The brightness of cutting highlights is affected by the milling bit speed. The faster the bit speed is, the brighter the cutting highlights will be, and the darker the cutting highlights will be and the cutting pattern will be easily produced. Metal processing WeChat, the content is good, worthy of attention. High-gloss and high-gloss cutting is especially common in the application of mobile phones, such as iphone5. In recent years, some high-end TV sets have adopted high-gloss milling technology in their metal frames. In addition, anodic oxidation and wiredrawing technology make the TV sets full of a sense of fashion and sharp sense of technology.
Anodic oxidation
Anodic oxidation refers to the electrochemical oxidation of metal or alloy, aluminum and its alloy in the corresponding electrolyte and specific process conditions, due to the effect of the applied current on the aluminum product (anode), forming a layer of oxide film process. Anodic oxidation can not only solve the aluminum surface hardness, wear resistance and other defects, but also extend the service life of aluminum and enhance the beauty, has become an indispensable part of aluminum surface treatment, is the most widely used and very successful process.
6. Two-color anodic oxidation
Two-color anodizing refers to anodizing a product and giving a specific area a different color. Because of the complicated process, the cost of two-color anodic oxidation is high. But through the contrast between the two colors, can reflect the product's high-end, unique appearance
