Aluminum Alloy Surface Treatment 6 Big Craft, Here Is The Most Complete!
Jul 20, 2017

Metal materials in the existing use of various types of products more and more, because the metal material better reflect the product quality, highlighting the brand value, and in many metal materials, aluminum because of its easy processing, visual effects, Surface treatment means rich, bear the brunt of being used by various manufacturers, aluminum surface treatment is divided into: sandblasting (matte pearl silver surface), polished (the formation of mirror), drawing (forming a similar satin effect), plating Layer other metal), spray (cover other non-metallic coating)

The following metal processing Xiaobian will bring you some easy picture, with the tight metal processing WeChat, together with our daily experience in the aluminum and aluminum alloy surface processing technology.

Sandblasting

The process of cleaning and roughening the metal surface with 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 workpiece surface is improved, thus improving the fatigue resistance of the workpiece, increased between it and the coating Of the adhesion, extending the durability of the coating, but also conducive to the leveling and decoration of the paint. The process we often see in Apple's various products, as well as by the existing TV case or in the box is also more and more used.

Polish

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 using mechanical polishing + electrolytic polishing can be close to the stainless steel mirror effect, giving a high-grade simple, stylish future feeling (of course, easy to leave fingerprints but also more care).

3. 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 drawing, thread drawing. Metal processing WeChat, the content is good, worthy of attention. Metal wire drawing process, you can clearly show every fine silk marks, so that the metal matte glow in the fine hair luster, both fashion products and technology.

4. High light cutting

The use of carving machine will be reinforced diamond knife in high-speed rotation (the general speed of 20000 r / min) carved machine spindle cutting parts, in the product surface to produce local highlight area. The brightness of the cutting high light is affected by the speed of the milling bit. The faster the bit is, the faster the bristles are, and the darker it is. Metal processing WeChat, the content is good, worthy of attention. High-light 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.

5. Anodizing

Anodic oxidation refers to the electrochemical oxidation of metals or alloys, 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.

6. 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, higher cost; but through the contrast between the two colors, better reflect the high-end products, unique appearance.
