The unique tools and aluminum alloy materials of the mobile phone case are specifically used in the shell, the middle frame, the card, the side button, and the back cover processing.
Battle 1: Aluminum alloy materials are endless. The traditional one is 1 series, 5 series, 6 series, 7 series, in order to be satisfied with high strength, high end, high end oxidation, the effect of stamping, and the effect of oxygen. The corresponding cutting fluid may be developed in a timely manner according to the different aluminum alloy to meet the requirements of different materials. Battle 2: Fine diecasting has achieved great development in recent years. The working hours of CNC processing CNC processing are too long. For example, a middle frame is sometimes consumed by half an hour, the process is single, and the interior can be formed in a single. Cracks, the appearance cannot be performed with outstanding anode oxidation. The golden plastic co -surface will constitute the spraying process more complicated and the yield rate is low. But it also got gratifying development. 1. The continuous optimization of fine die casting technology, Guangdong's die casting industry is extremely prosperous. Mold use. 2. Embedded die -casting, compared to CNC processing, has a lower capital and can also satisfy the needs of anode oxidation. Now it is only unsatisfactory to change the function of the data function after the plane and die casting. 3. Modification of aluminum alloy data, decrease in silicon and copper content, increase zinc, degree, magnesium, manganese content, improvement intensity and reduction of iron reduction, and improve the anode effect. 4. PVD coating plan, combine the low capital of die -casting and the appearance of PVD coating, which can be anode oxidation, and satisfies the requirements of the shell production. Battle 3: the use of ceramics, stainless steel and titanium alloy. In order to improve barriers and added values, the industry leading companies have already deployed ceramics, stainless steel and titanium alloys. The first two types of data are unique to self -passivation, self -correction effects, and excellent corrosion resistance. However, as the corresponding water -based cutting fluid, it must be satisfied with high lubrication, low oily mist, and long life. It must be a major war. Generally, the previous two types of materials are oil -based. Ceramics are very different for previous cutting fluids. Battle 4: The adjustment of the aode oxidation process makes some die castings be satisfactory. The electrolyte adjustment, using mixed acid anode oxidation and organic acid anode oxidation, decreased the oxide film, and improved the corrosion resistance of anode oxide film. The adjustment of the electrolytic method uses positive pulse electrolysis and two ways pulse electrolysis to improve the fineness and corrosion resistance of the membrane.
The various problems described above are only needed to develop a breakthrough in one or more comprehensive applications, and it is also necessary to move forward. These will definitely cause the use of the cutting fluid to shake the cliff shape in the use of the mobile phone case. The cutting fluid has a large -scale output value on mobile phones, and the competition is highly heated. There are comprehensive product lines and cases of mobile phone cases, and in the discussion of basic data such as synthetic esters and rust -proof agents, cutting liquid advantages supply the market.
