Metal material in the existing types of products with more and more, because of metal material can reflect the quality of the product, highlight the brand value, and in various metal materials, aluminum because of its easy processing, good visual effect, surface treatment means rich, be the first to be affected by various manufacturers using, aluminum surface treatment is mainly divided into: matte pearl silver surface forming (sandblasting), polishing (mirror formation) and drawing (forming similar Satin effect), electroplating (covering a layer of other metal), spraying (covering other non-metallic coating).

There are different surface treatments of aluminum and aluminum alloy in our daily production.
1. Sandblasting (shot peening).
The process of cleaning up and rough metal surfaces using the impact of high speed sand flow. This method of aluminum surface treatment can make the surface of the workpiece to obtain a clean degree and different roughness and improved the mechanical properties of the workpiece surface, thus improving the fatigue resistance of the workpiece, increase the adhesion between the coating and it, to extend the durability of the coating, but also conducive to coating leveling and decoration. This process we often see in the various products of the Apple Corp, as well as the existing TV box or box is also more and more used.

2. Polishing.
By using mechanical, chemical or electrochemical methods, the surface roughness of the workpiece is reduced, and the processing method of the bright and smooth surface is obtained. Polishing process is mainly divided into: mechanical polishing, chemical polishing, electrolytic polishing. Aluminum parts using mechanical polishing and electrolytic polishing can be close to the effect of stainless steel mirror, give people with high-grade simplicity, fashion sense of the future (of course, easy to leave fingerprints and more care).

3. wire drawing.
Metal wire drawing aluminum plate is repeatedly scraped manufacturing process lines with sandpaper. Drawing can be divided into straight lines drawing, random lines drawing, spiral pattern wire drawing, thread drawing. Metal processing WeChat, the content is good, it is worth attention. Metal wire drawing process can be clearly revealed each a piece of fine filaments marks, so that the matte metal pan fine hair luster and a sense of both products of fashion and technology.

4. High light cutting.
The carving machine will diamond knife reinforcement in high speed rotating speed (typically to 20000 RPM / points) of engraving machine spindle cutting parts, on the surface of the product generated local highlight area. Cutting of high light brightness is affected by the influence of milling bit speed, bright bit faster cutting of high Guangyue. Conversely, more dark and easy to produce knife grain. Metal processing WeChat, the content is good, it is worth attention. High light and high light cutting in the use of mobile phones, such as the iPhone, in recent years some high-end television metal frame using the high light milling process, coupled with anodic oxidation and drawing process, and makes the overall TV full of fashion and sense of science and technology of the sharp feeling.

5. Anodic oxidation.
Anodic oxidation is refers to the electrochemical oxidation of metal or alloy, aluminum and its alloys in the corresponding electrolyte and specific process conditions, due to the impressed current, in aluminum products (anode) form a layer of oxide film. Anodic oxidation can not only solve the defects of aluminum surface hardness, wear resistance and other aspects of the, more can the service life of the aluminum and enhance the appearance of extending the, has become indispensable aluminum surface treatment, is currently the most widely used and very successful process.

6. Dual color anodic oxidation.
Dual color anodic oxidation is a product which is carried out on a product to be oxidized to a specific area of different colors. Because the process is complex and the cost is high, the dual color anodic oxidation process can reflect the high-end and unique appearance of the product through the contrast between the two colors.
