1. Polishing
Use mechanical, chemical or electrochemical techniques to reduce the roughness of the aluminum profile surface to obtain a bright and smooth surface. Polishing technology is mainly divided into machine polishing, chemical polishing and electrolytic polishing. After machine polishing and electrolytic polishing, the aluminum parts of the car can be close to the stainless steel mirror effect, giving people a feeling of high-end, simple and fashionable in the future.
2. Sandblasting
The process of cleaning and roughening the metal surface through the impact of high-speed sand flow. Surface treatment of aluminum profiles by this technique can obtain a certain degree of cleanliness and different roughness on the surface of aluminum profiles, improve the mechanical properties of the workpiece surface, thereby improving the fatigue resistance of the workpiece, and increasing the distance between the workpiece and the coating. Adhesion, extending the durability of the coating film, is also beneficial to the leveling and decoration of the coating. We often see this process in solar bezels, and it is increasingly being used in existing TV casings or middle frames.
3. Drawing
Metal wire drawing is the process of repeatedly scraping the aluminum plate out of the line with sandpaper. Drawing can be divided into straight drawing, random drawing, spiral drawing and rib drawing. Metal processing WeChat is rich in content and deserves attention. The metal wire drawing process can clearly show every tiny line mark, so that the metal matte shines, with a delicate hair shine, and the product is equipped with fashion and technology.
4. Strong light cutting
The diamond knife is strengthened by the finishing machine to cut the parts on the high-speed twisting (20000 rpm) finishing machine spindle, thus creating some high-gloss areas on the surface of the product. The brightness of the cutting highlights is affected by the speed of the milling cutter. The faster the drill speed, the brighter the cutting highlights, conversely, the darker the cutting highlights, the easier it is for the cutting patterns to occur. Highlight cut is often used in mobile phones. In recent years, some high-end TV metal frames have adopted high-gloss milling technology, coupled with anodizing and brushing technology, which makes the TV as a whole full of fashion and technology.
5. Anodizing
Anodization refers to the electrochemical oxidation of metals or alloys. Under the premise of responding to electrolytes and specific processes, aluminum and its alloys form an oxide film on aluminum products (anodes) under the benefit of applied current. Anodizing can not only solve the defects of aluminum surface hardness and wear resistance, but also prolong the service life of aluminum and enhance the appearance of aluminum. It has become an indispensable part of aluminum surface treatment, and it is a widely used and successful process at present .
6. Two-color anodizing
Two-color anodizing refers to anodizing the product and giving different colors to specific areas. The two-color anodizing process is complicated and expensive. However, through the contrast of the two colors, it can better reflect the high-end and unique surface of the product.
