                      Aluminum alloy processing technology for five methods|



1. Sand blasting is also called shot blasting


The process of cleaning and coarsening metal surfaces by the impact of high speed sand flow. This method of surface treatment of aluminum parts can make the surface of the workpiece to obtain a certain degree of cleanliness and different roughness, so that the mechanical properties of the surface of the workpiece are improved, 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 the paint flow and decoration. This aluminum alloy process is often seen in Apple's various products, and is increasingly used in existing TV covers or middle frames.


2. The polishing


A process in which the surface roughness of automobile aluminum parts is reduced by mechanical, chemical or electrochemical methods to obtain a bright and smooth surface. Polishing process is mainly divided into: mechanical polishing, chemical polishing, electropolishing. Automotive aluminum parts using mechanical polishing + electrolytic polishing can be close to the stainless steel mirror effect, giving a person with high-grade simple, fashionable future feeling (of course, easy to leave fingerprints but also more care).


3. The drawing


Wire drawing is the manufacturing process of repeatedly scraping an aluminum sheet out of the wire with sandpaper. Wire drawing can be divided into straight wire drawing, random wire drawing, spiral wire drawing, thread drawing. Metal processing WeChat, good content, worthy of attention. Metal wire drawing process, can clearly show every tiny silk mark, so that the metal matte in the spread of fine hair luster, the product has a sense of fashion and science and technology.


4. Specular cutting


The diamond cutter is reinforced by the engraving machine in the high speed rotation (general speed is 20000 RPM) of the engraving machine spindle to cut parts, resulting in local highlighting area on the surface of the product. The brightness of the cutting highlight is affected by the speed of the milling bit. The faster the bit speed is, the brighter the cutting highlight will be, while the vice versa. Metal processing WeChat, good content, worthy of attention.


5. Anodizing


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 action of external current, in the process of forming a layer of oxide film on the aluminum products (anode). Anodic oxidation can not only solve the aluminum surface hardness, wear resistance and other aspects of the defects, but also can extend the service life of aluminum and enhance the beauty, has become an indispensable part of the aluminum surface treatment, is the most widely used and very successful process.
