1. Sand spray is also called spray ball
The process of cleaning up the impact of high -speed sand flow and the surface of rough metal. The surface treatment of this method can make the surface of the workpiece obtain a certain cleanliness and different roughness, so that the mechanical properties of the surface of the workpiece can be improved. The adhesion is extended to the durability of the coating film, and it is also conducive to the flatness and decoration of the paint. We often see in various products of Apple in this aluminum alloy process, as well as more and more adopted by existing TV shells or middle frames.
2. Polish
Use mechanical, chemical or electrochemical methods to reduce the surface roughness of the car aluminum parts to obtain a bright and flat surface processing method. The polishing process is mainly divided into: mechanical polishing, chemical polishing, electrolytic polishing. Automotive aluminum parts use mechanical polishing+electrolytic polishing can get close to stainless steel mirror effects, giving people a high -end simplicity, fashionable future feeling (of course, it is easy to leave fingerprints and more care).
3. Rita
Metal drawing is the manufacturing process where the aluminum plate is scraped out of the line repeatedly. Bittable can be divided into straight lines, rustic roses, rotor roses, and threading. Metal processing WeChat, good content and worthy of attention. The metal brushed process can clearly show each fine silk marks, so that the metal matte has a fine shiny shiny, and the product has both fashion and technology.
4. Highlight cutting
The diamond knife is used to reinforce the diamond knife on the main axis of the meticulous carving machine with a high -speed rotation (general speed is 20,000 rpm) to cut the cut parts to generate a local high -bright area on the surface of the product. The brightness of the cutting highlight is affected by the speed of the milling drill. The faster the drill speed, the brighter the highlights of the cutting. Metal processing WeChat, good content and worthy of attention.
5. anode oxidation
Anode oxidation refers to the electrochemical oxidation of metal or alloy. Under the corresponding electrolytes and specific process conditions of aluminum and alloys, due to the influence of external current, the process of forming a layer of oxide on aluminum products (anode). The anode oxidation can not only solve the defects of aluminum surface hardness, wear resistance, etc., but also can prolong the life of aluminum and enhance the beauty. It has become an indispensable part of aluminum surface treatment. It is currently the most widely used and very successful application. Process.
