After the aluminum alloy prototype is CNC machined, it needs to go through a series of surface treatments to obtain a bright and beautiful prototype model. So what are the surface treatment effects of aluminum alloy prototype? Today, Dongguan ganzoo Prototype Manufacturing Co., Ltd. will tell you about several post-processing of CNC aluminum alloy processing
1. Sand blasting is also called shot blasting
The process of cleaning and roughening metal surfaces using the impact of high-speed sand streams. The aluminum 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 workpiece surface are improved, so as to improve the fatigue resistance of the workpiece, increase the adhesion between it and the coating, extend the durability of the coating film, and also facilitate the leveling and decoration of the coating.
2. Polishing
Using mechanical, chemical or electrochemical methods, the surface roughness of automotive aluminum parts is reduced 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 can approach the stainless steel mirror effect after mechanical polishing + electrolytic polishing, giving people a high-end simple, fashionable future feeling (of course, it is easy to leave fingerprints and take more care).
3. Wire drawing
Wire drawing metal is a manufacturing process in which aluminum sheets are repeatedly scraped out of line with sandpaper. Wire drawing can be divided into straight grain wire drawing, random grain wire drawing, rotary wire drawing, thread wire drawing. The metal drawing process can clearly show every fine silk mark, so that the fine hair shine in the metal matte, the product is both stylish and technological.
4. High-gloss cutting
The diamond engraving machine is used to reinforce the diamond knife on the spindle of the engraving machine rotating at high speed (generally 20,000 rpm) to cut the parts, and produce a local highlight 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 highlight of cutting, and vice versa, the darker and prone to knife lines.
5. Anodizing
Anodizing refers to the electrochemical oxidation of metals or alloys, and the process of forming an oxide film on aluminum products (anodes) on aluminum products (anodes) under the corresponding electrolyte and specific process conditions, due to the action of applied current. Anodizing can not only solve the defects of aluminum surface hardness, wear resistance, etc., but also extend the service life of aluminum and enhance aesthetics, which has become an indispensable part of aluminum surface treatment and is currently the most widely used and very successful process.
