5g mobile phone automatic oil spraying equipment 5g mobile phone tablet computer automatic spraying production line Huawei 5g mobile phone coating equipment automatic 5g spraying equipment Shenzhen Zhicheng automation equipment Co., Ltd. 5g era is coming, mobile phone shell materials from plastic to metal to non-metallic materials, plastic glue because of low cost, favored by the low-end market. from IML to IMT, the plastic becomes white and rich, which can be close to the 3D optical texture of glass back cover, which has become the choice of many CMF designers. LDS has been widely used in the 4G era plastic rear shell antenna, but whether it can adapt to the high-end curved glass 3D back cover in 5g era needs to continue to layout and research. IMT technology can also be further extended to ime technology, which integrates electrical and decorative functions and can be applied to the future automotive intelligent surface. As a kind of low cost and efficient product form, injection molded transparent PC back cover has better impact strength and durability, which is attracting more and more attention of traditional plastic factories. The principle of LDS technology is to excite the metal particles of the plastic shell containing metal components by laser, and surface the copper sheet on the plastic by environmental protection electroplating technology. The copper sheet can directly turn the mobile phone shell into an antenna to receive signals in three-dimensional space Advantages of LDS Technology: ; mobile devices (smart phones, tablet computers and laptops) tend to be large screen, thin body and multi-function, and the requirements for antennas are increasingly stringent. In addition, it has advantages over the traditional mobile communication technology, such as Bluetooth, Bluetooth, and so on Machine (FM Radio) save space on the thin and complex structure of portable mobile devices ; reduce the interference of different types of antennas, reduce the probability of signal degradation caused by users' touching the antenna directly ; it can be widely used in smart phones, laptops and tablet computers ; development trend: ; in the 5g era, high-end smart phone terminal antenna needs to be on the 3D glass back cover and curved knot of 3D glass The structure is not suitable for 5g antenna contact placement, which is a technical problem at present. Recently, according to the media, BYD already has the technical reserve for mass production of 5g antenna in 3D glass back cover. Whether the LDS antenna can adapt to curved 3D glass needs to be further studied. IMR technology IMR technology is a kind of in mold decoration. It was developed by Nissha printing in 1980. Since 2006, it cooperated with HP to launch color case notebook computer. IMR technology has become the mainstream process of notebook computer shell processing, and has been widely used in mobile phone terminals. The principle of IMR process of 5g mobile phone tablet computer automatic spraying production line: the ink is printed on a PE film, and the metal material can also be evaporated on the PE film to form a whole roll. After the film printing position is aligned with the position to be printed in the mold cavity, the film is molded with plastic, and the molded product is combined with the ink but separated from the film After the forming action of the next mold, the surface of the finished product is hardened after UV irradiation. imr process can achieve different decorative effects (leather, cloth, bamboo, stone, etc.), and the advantage is to change the film to show different patterns. The IMR back cover applied on Xiaomi 4 is called "grating pattern back cover" by millet. development trend: oppo A79 adopting IMT process has been selling well. At present, the problem encountered by IMT is that the yield still needs to be improved. In the 5g era, the IMT process may become very popular. According to Xiaobian's understanding, many domestic manufacturers such as Tongda, Zhaoyi, Lianmao, Yuding nano, BYD, Jingfeng and Huanli are all in the layout, and some enterprises have begun mass production. In the future, IMT technology will be able to integrate with electronic technology and evolve into ime technology. The circuit layer will be added and electronic components will be attached. The film will be endowed with electronic functions and various visual, tactile and sensory effects, which will be applied to the intelligent surface of future automobiles. 5, PC glass injection molding process injection transparent PC back cover as a lower cost, efficient product form, with better impact strength and durability, is attracting more and more attention of traditional plastic manufacturers, and is expected to become the mainstream mobile phone back cover scheme in 2019. It is understood that several manufacturers such as Sanjing, Shuo Beide, Tongda, Lianmao, BYD, Dongfang Liangcai, Jierong, xiuqiang, Jinsheng, xinwanda, Huike and other manufacturers are accelerating the layout of injection molding transparent PC mobile phone back cover. Mitsubishi Chemical, SABIC and other raw material manufacturers are also verifying that the special material for PC injection molding mobile phone back cover can meet the requirements of high hardness, low stress and no rainbow pattern. Advantages of PC glass imitation injection molding process: compared with PC glass imitation injection molding process, it is easier to add quantity and has high efficiency. It can achieve the effect of imitating 2.5d/3d glass shell, and decorate by spraying (without coating) and pasting film. Oppo realme is the water test of PC injection molding imitating 2.5D glass shell. development trend: in 2018, the composite plate has been widely used as the back cover scheme of imitation glass mobile phone, but at present, the production capacity is limited, the product is easy to deform, the investment risk is high, and the space for process improvement and cost reduction is not large. Glass and ceramics are too expensive and fragile. Large scale production and good product rate make it more suitable for high-end models. In the case that the cost of glass and 3D composite board is difficult to decline in a short time, plastic injection molding mobile phone back cover as an efficient and low-cost alternative came into being, and rose rapidly
