With the aluminum roll more and more widely into our lives, we have higher and higher requirements for the quality of aluminum roll. What kind of aluminum coil will attract more users? It is necessary to focus on the visual effect and surface treatment of aluminum coil. Here are six unique techniques for the surface treatment of aluminum coil:

Sand blasting (shot blasting) : the process of cleaning and coarsening metal surface by the impact of high-speed sand flow. This method of aluminum surface treatment 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 anti-fatigue of the workpiece, increase the adhesion between it and the coating, extend the durability of the coating, is also conducive to the smooth decoration of the coating. This process is often seen in various apple products and is increasingly used in existing TV cases or frames.

Two: polishing: the use of mechanical, chemical or electrochemical methods to reduce the surface roughness of the workpiece, in order to obtain bright, smooth surface processing method. Polishing technology is mainly divided into: mechanical polishing, chemical polishing, electrolytic polishing. Aluminum using mechanical polishing + electrolytic polishing can be close to the mirror effect of stainless steel, give a person with high-grade simple, fashionable future feeling (of course, easy to leave fingerprints but also more care).

Three: wire drawing: metal wire drawing is the manufacturing process of repeatedly scraping aluminum roll out of the wire with sandpaper. Drawing can be divided into straight line drawing, random drawing, spiral drawing, thread drawing. Metal processing WeChat, content is good, worthy of attention. Metal wiredrawing technology, can clearly show every trace of fine silk, so that the metal matte in the spread of fine hair luster, products have a sense of fashion and technology.

Four: highlights: cutting using fine carving machine diamond knife reinforcement in high speed rotation (general rotation speed of 20,000 RPM) of the fine carving machine spindle to cut parts, on the surface of the product to produce local highlight area. The brightness of cutting highlights is affected by the speed of the milling bit. The faster the bit speed is, the brighter the cutting highlights will be. Metal processing WeChat, content is good, worthy of attention. High-gloss high-gloss cutting is particularly common in the application of mobile phones, such as iphone5. In recent years, some high-end TV sets have adopted the high-gloss milling process of metal frame, and the anodic oxidation and wiredrawing process make the TV set full of the sharp sense of fashion and technology.

Anodic oxidation: anodic oxidation refers to the electrochemical oxidation of metal or alloy. After aluminum coil is cut into sheet form, an oxidation film is formed on aluminum products (anode) under the action of applied current under the corresponding electrolyte and specific technological conditions. Anodic oxidation can not only solve the surface hardness, wear resistance and other defects of aluminum, but also extend the service life of aluminum and enhance the appearance, has become an indispensable link of aluminum surface treatment, is currently widely used and very successful process.

Two-color anodizing: two-color anodizing is the anodizing of a product to give different colors to specific areas. The cost of two-color anodic oxidation is high because of its complicated technology. But through the contrast between the two colors, more can reflect the high-end, unique appearance of the product.

Through these six unique techniques, can greatly improve the appearance of aluminum roll image and quality, improve user experience, so that more and more users like your products, if you have this need and help, please contact us.
