The process of polishing a smooth shell to a non-smooth surface so that light is diffused on the surface. The frosting process has the characteristics of not being easy to leave fingerprints, more comfortable to touch, and having better skid resistance.
Piano painting process
The piano painting process refers to the high precision spray painting and long-time surface treatment of the shell material, and finally, making the surface of the crystal texture of the gorgeous luster. It should be pointed out that the process is easy to scratch the surface and leave fingerprints, and difficult to clean. Mainstream notebook manufacturers eliminate this process.
Intramembrane printing technology
Internal film printing technology is a kind of casting mold coating technology, adding a layer of transparent coating on the surface of the molding product, the inner layer of the coating can also be designed embossing pattern, texture pattern inlaid between the notebook shell, and the upper paint surface, forming a beautiful and generous protective layer. Not only does has a very good visual effect, but also can play the role of anti-wear. But it leaves fingerprints.
Anodic oxidation
Anodizing is the conversion of aluminum and aluminum alloys into an oxide film, which has protective, decorative, and other functional properties. For example, improve corrosion resistance, enhance wear resistance and hardness, protect the metal surface, etc. Models such as the ThinkPad S5 use this type of finish.
Metal wire drawing
The aluminum plate is repeatedly scraped out of the wire strip. In this process, a special skin film layer is generated by anodizing, which can clearly show every tiny wire mark. According to the need, the wire drawing can be made into straight lines, random lines, thread ripples, etc. This process is resistant to corrosion, not easy to leave fingerprints, but not resistant to scratch.
Class skin coating
The chlorinated rubber or PU is melted in the solvent to become a liquid and then sprayed onto the laptop shell by spray painting equipment. After the solvent evaporates, the coating is formed. Moreover, Think added titanium particles to the shell coating to enhance the wear resistance of the coating. This process has a good hand feel, anti-sliding, and large damping. But in the process of use to avoid collision, scratch, and other problems.
