Mingtai Aluminum offers you the five major processes for aluminum alloy processing
- 2017-10-13 09:17 -
Aluminum has a range of properties that are superior to other nonferrous metals, steel, plastic and wood, such as good corrosion resistance and rust resistance; good plasticity and processing properties; good thermal conductivity and conductivity; Low temperature performance, so the use of a very wide range, then the treatment process is also very important, the following describes the aluminum alloy processing technology.
1, polished
The use of mechanical, chemical or electrochemical methods to reduce the surface roughness of the workpiece in order to obtain bright, flat surface processing methods. Polishing process is divided into: mechanical polishing, chemical polishing, electrolytic polishing. Aluminum parts with mechanical polishing + electrolytic polishing can be close to the stainless steel mirror effect, giving a high-end simple, stylish future feeling (of course, easy to leave fingerprints but also more care).
2, drawing
Metal wire drawing is repeated with sandpaper to scrap the aluminum plate manufacturing process. Drawing can be divided into straight wire drawing, chaos drawing wire, wire drawing, thread drawing. Metal wire drawing process, you can clearly show every fine silk marks, so that the metal matte glow in the fine hair shiny, both fashion products and technology.
3, high light cutting
Strengthen the diamond knife in the high-speed rotation (general speed of 20000 r / min) engraving machine spindle cutting parts, in the product surface to produce local highlights area. The brightness of the cutting high light is affected by the speed of the milling bit. The faster the bit is, the brighter the bristles of the cutting, and the darker it is. High-light cutting in the use of mobile phones in particular, such as iphone5, in recent years, some high-end TV metal frame with a high light milling process, coupled with anodizing and drawing process makes the whole TV is full of fashion sense and technology sharp sense.
4, anodized
Anodic oxidation refers to the electrochemical oxidation of metal or alloy, aluminum and its alloys in the corresponding electrolyte and specific process conditions, due to the role of external current in the aluminum products (anode) on the formation of a layer of oxide film process. Anodic oxidation not only can solve the aluminum surface hardness, wear resistance and other defects, but also to extend the life of aluminum and enhance the aesthetic degree, has become an indispensable part of aluminum surface treatment, is currently the most widely used and very successful Process.
5, two-color anodized
Two-color anodic oxidation refers to the oxidation of anodic oxide on a product and imparts a different color to a particular area. Two-color anodic oxidation because of the complexity of the process, the higher the cost; but through the contrast between the two colors, better reflect the high-end products, unique appearance.
