Surface treatment process of aluminum alloy
01 sandblasting
The process of cleaning and coarsening metal surfaces by the impact of a high-speed sand stream. The surface treatment of the aluminum part by this method can make the surface of the workpiece obtain certain cleanliness and different roughness, and the mechanical properties of the surface of the workpiece are improved, so the fatigue resistance of the workpiece is improved, the adhesion between the coating and the coating is increased, the durability of the coating is prolonged, and the leveling and decoration of the coating are also advantageous. This process is often seen in apple's various products, and is increasingly used in existing TV cases or in the frame.
02 polishing
A process that uses mechanical, chemical, or electrochemical means to reduce the Surface roughness of a workpiece in order to obtain a bright, smooth surface. Polishing process is mainly divided into: Mechanical Polishing, chemical polishing, electrolytic polishing. Aluminum Parts with mechanical polishing + electrolytic polishing can be close to the mirror effect of stainless steel, giving people a high-grade simple, up-to-date feeling (of course easy to leave fingerprints and more care) . Here's a quick video:
03 wire drawing
Metal wire drawing is the process of repeatedly using sandpaper to scrape the aluminum plate out of the line. Wire drawing can be divided into straight wire drawing, random wire drawing, spiral wire drawing, thread drawing. Metal drawing process, you can clearly show each fine wire marks, so that the metal matte in the pan-fine hair luster, both fashion and technology products sense.
04 Bloom cutting
The diamond cutter is strengthened by the engraving machine on the spindle of the engraving machine with high speed rotation speed (20000 RPM / Min) to cut the parts and produce local highlight area on the surface of the products. The brightness of the bloom is affected by the speed of the milling bit, the faster the bit is, the brighter the bloom is, and vice versa, the darker and more prone to tool marks. Bloom Bloom has cut a lot in mobile phones, such as the iphone 5, and in recent years some high end TV sets have used bloom milling technology for their metal frames, in addition, anodizing and wire drawing process makes the TV set full of fashion sense and sharp sense of technology.
05 anodic oxidation
Anodizing is the electrochemical oxidation of metal or alloy, aluminum and its alloy in the corresponding electrolyte and specific process conditions, due to the effect of external current, in aluminum products on the formation of a layer of oxide film on the anode process. Anodizing not only can solve the defects of surface hardness and wear resistance of aluminum, but also can prolong the service life of aluminum and enhance its beauty. It has become an indispensable link in aluminum surface treatment, is currently the most widely used and very successful process.
06 two-color anodizing
Two-color anodizing is the process of anodizing a product to give different colors to a specific area. The process of two-color anodizing is complex and the cost is high, but the contrast of two-color anodizing can reflect the high-end and unique appearance of the product.
