In this age of the beauty economy, exquisite products are frequently regarded as being of greater value, and consumers are more willing to pay for them, even if the cost is higher. The look and the feel of the surface are what contribute to what is referred to as the material's texture. Surface treatment is a very important factor that contributes to this sensation. Polishing, high-gloss milling, and wire drawing are just some of the surface treatments that are performed on the shell cnc machining parts of an Apple laptop after it has been formed from a single piece of aluminum alloy using CNC processing. Another example is the casing of an Apple laptop, which is made from an entire piece of aluminum alloy. Texture exists alongside a sense of fashion as well as technological advancement.
Processing aluminum alloy is simple, and it offers a variety of surface treatment options in addition to having attractive visual effects. It finds widespread application in products such as LED desk lamps, cameras, notebook computers, mobile phones, and mobile solid-state hard drives PSSD, amongst other things. Polishing, wire drawing, sandblasting, high-gloss cutting, and anodizing are all examples of surface treatment processes that are frequently combined with it in order to give the product a variety of different textures.
However, polishing does not improve the dimensional accuracy or geometric shape accuracy of the part; rather, it is used to obtain a smooth surface or a mirror-gloss appearance. The polishing process primarily reduces the roughness of the metal surface through mechanical polishing or chemical polishing. The use of sandpaper or polishing wheels is CNC Turning Services what is meant by the term "mechanical polishing. " This technique is used to make the surface of the metal more smooth and shiny. In spite of this, aluminum alloy does not have a particularly high level of hardness; consequently, the use of coarse-grained grinding and polishing materials will result in the formation of deep grinding lines. If the fine grain size is used, the surface will be smoother; however, the capability to remove milling lines will be significantly diminished.
Chemical polishing is an electrochemical process that can be thought of as reverse plating online cnc machining service because it removes a thin layer of material from the surface of the metal. The result is a surface that is smooth, ultra-clean, has a uniform luster, and does not have fine lines like those that appear with physical polishing. In the field of medicine, chemical polishing can make surgical tools easier to clean and disinfect than they would be otherwise. Chemical polishing products are used in home appliances such as refrigerators and washing machines to make parts last longer and look brighter. Examples of these types of appliances include. When applied to critical aircraft components, chemical polishing can help reduce frictional resistance, which in turn makes the aircraft more energy-efficient and safer.
Sandblasting is used on the surface of a lot of different electronic products so that the surface can be made to look less shiny and more matte. The matte material is somewhat analogous to frosted glass in that it is subdued and serene, thereby contributing to the product's understated and long-lasting quality. Compressed air is used as the power source for sand blasting, which then causes materials such as copper ore, quartz sand, corundum, iron sand, sea sand, and so on to be sprayed at high speed onto the surface of aluminum alloy. This alters the mechanical properties of the surface of aluminum alloy parts and improves the fatigue resistance of parts. Sand blasting can also increase the adhesion between the original surface of the part and the coating, which is more beneficial to the durability.
It is possible to arbitrarily select between different roughnesses during the sandblasting surface treatment process, which allows for the formation of different roughnesses on the surface of aluminum alloy parts. This makes it the cleaning method that is both the quickest and most thorough. It is also useful in automotive interiors, and the center console of the drawing panel can also be used to improve car quality. Drawing technology is very common in the design of products, such as notebooks and headphones in electronic products; refrigerators, air purifiers, and other such products in household products.
By repeatedly scraping the lines with sandpaper on the aluminum plate, it is possible to clearly show every single tiny silk mark. This causes the metal matte to glow with a fine hair luster, which lends the product a kind of fortitude as well as beauty. It is possible to fashion it into a variety of different types, such as straight grain, random grain, and spiral grain, according to the requirements of the decoration. The interior of the microwave oven that took home the IF award has a brushed finish on the surface. Utilizing an engraving machine to cut parts while simultaneously milling a local highlight area on the surface of the product is how the high-gloss milling process is carried out. The metal appearance of some small pieces is milled with one or more lines, while the metal shell of some mobile phones is milled with a circle of highlight chamfers. The surface of the product is made to appear more fashionable and bright thanks to the shallow grooves that run in straight lines.
Some high-end TV metal frames have adopted high-gloss milling technology in recent years. This technology, when combined with anodizing and wire-drawing technology, gives the TV set a strong sense of both fashion and technology. The majority of the time, aluminum components are not appropriate for electroplating because aluminum components easily form an oxide film when exposed to oxygen. This has a significant impact on the bonding force of the electroplating layer, so aluminum components are typically not suitable for electroplating. In most cases, anodic oxidation is the method of choice. The process of electrochemically oxidizing metals online machining services or alloys is referred to as anodizing. When certain conditions are met, including the application of a current, the surface of the parts will develop a layer of aluminum oxide film. This will result in an increase in both the surface hardness and the surface wear resistance of the parts, as well as an improvement in their resistance to corrosion.
The surface of the parts can also be colored into a variety of beautiful and bright colors thanks to the adsorption capacity of a large number of micropores in the thin oxide film. This improves the color performance of the parts and increases the aesthetic value of the product. In addition to the five surface treatments described above for aluminum alloy parts, Sujia is able to provide additional surface treatment processes, including decorative chrome plating, chrome plating, nickel plating, silver plating, gold plating, baking paint, plastic spraying, Teflon spraying, silk screen printing, and laser marking. These processes are utilized to meet the various technical requirements of the parts.
