With the development of science and technology, many new materials and processes have been gradually discovered. The micro arc oxidation process is applied to the treatment of many metal materials. By putting metal products into the electrolyte, and then applying voltage to metal products, under the combined action of current and electrolyte, the surface of metal products will produce a layer of corrosion resistant, high toughness, impact resistant protective film. Compared with other processes, the micro arc oxidation process has the advantages of simplicity and environmental protection. Therefore, it is widely used in the treatment of various metal materials by many large factories. At present, some well-known notebook computer manufacturers, such as Microsoft, Lenovo, Dell, etc., will use the micro arc oxidation process to treat the computer shell during the production of computers, which can enhance the comprehensive performance of computers. PPS material manufacturers take you into the micro arc oxidation process.

Due to the improvement of China's economic level, laptops have become an indispensable tool for people to work and study. The computer shell we usually see is made of pure metal, so there is a disadvantage, shielding the signal. The computer shell has an antenna slot, which is specially used to receive signals. If metal materials are used, the stability of signals will be affected. Therefore, computer manufacturers are looking for a suitable material to make the antenna slot. PPS material has become an excellent antenna slot material, but PPS materials on the market can only withstand 300V voltage when conducting micro arc oxidation, which is far from enough for the computer shell, which is also a problem for many computer manufacturers.
