Mobile phone shell manufacturers tell you about the 25 years from 2G to 5G, look at the material and design changes of mobile phone shells

Explain in detail the three major eras of the development trend of mobile phone shell materials: the era of coexistence of multiple materials such as plastic and metal (early 2G-4G); the era of all-metal integrated monolithic fuselage (the second half of 4G); the era of glass, plastic and non-metallic (4.5G-5G) . The major feature of the mobile phone industry is that the rate of technological upgrading is extremely fast. Among them, every technological innovation of materials on mobile phones is basically a reshuffle of the field, which is caught off guard. Therefore, companies in the mobile phone industry chain It has been following the development trend and trembling. In the 25 years from 2G to 5G (1995-2020), materials have promoted the development trend of the field, from the early days when multiple materials such as plastic and metal coexisted, to the heyday of metal integration, and finally to the current age of glass, plastic, and non-metal. The continuous transformation of the field has also prompted the creation and rise of batches of well-known companies. Let us take a closer look in this article. According to the materials of mobile phone casings, the development trend of materials is mainly divided into three major eras (summarized at the end of the article): the era of coexistence of multiple materials such as plastic and metal (early 2G-4G); the era of all-metal integrated body (the second half of 4G) ); Glass plastic non-metal era (4.5G-5G). ◤ The era of coexistence of multiple materials such as plastics and metals (early 2G-4G). From 2G to 4G, from 1995 to 2014, most mobile phones were dominated by plastic and metal materials. At the same time, many models also used glass. , Wood, leather products, chemical fiber and other materials, the design plan is very bold, and the housing materials are diversified. It means that well-known brands such as Motorola mobile phones, iPhone, LG, Samsung, etc., especially Nokia and Motorola mobile phones, can be said to dominate the mobile phone industry. At that time, there were many types of smart phones. Until the occurrence of the iPhone, all mobile phones had products. The styling design has embarked on a new level, and the sales market layout has also undergone tremendous changes. In addition to plastic and aluminum and magnesium metals, many mobile phones at that time also used glass, stainless steel, chemical fiber materials, skins, and wooden materials. It is unimaginable that these were mass-produced at that time! As shown in the figure below: the most traditional iPhone 4 is undoubtedly the prelude to the 3G era. It must be a cross-era work. The bold use of glass front and rear covers and stainless steel plate middle frames shocked everything. In the field, I heard that the cost was very expensive at that time. Figure Motorola mobile phone announced a variety of material mobile phones, including wood, leather, Kevlar, metal, bamboo charcoal fiber, etc. can be seen, this era not only more diversified product design on mobile phones, but also use more types of materials. The processing technology is mainly dominated by two-color injection molding, CNC, IML, painting, metal wire drawing, anodizing, PVD, etc. ◤ The era of all-metal monolithic fuselage (the second half of 4G) is actually in the 4G era (2012-2013), and some mobile phones have gradually used all-metal monolithic fuselage design solutions, among which the iPhone 5 series It is the classic meaning. The all-metal integrated body has a cool layering, which greatly improves the overall level of the mobile phone, especially the announcement of the iPhone 5 series all-metal integrated body, which promotes the development trend of metal cases, and gradually replaces plastic and other materials. (Squeeze to non-mainstream girls or hundreds of yuan machines and other series of products). Entering the second half of the 4G era, that is, around 2014, the all-metal integrated monolithic body announced the rise in all directions, and a wave of reform has swept all smartphone industries! At that time, most of the popular models used metal integrated body, the more well-known iPhone 6/7, Huawei Honor mobile phone, HTC series products and so on. The iPhone 6 made major changes in the overall specifications and formulation, and was the year-end sales champion at that time. The straw uses a 6-series aluminum-metal integrated design scheme, which uses 'secretion' to cover the significant sense of segmentation of the metal three-segment structure. The 6S and the 7th and 8th generations released later all use 5-series aluminum alloy profiles. An upgrade was carried out in materials. Among them, the gray-black version of iPhone 7 has entered the magnetic current grinding and polishing process, which once again improves the level of straw. At that time, the amount of information on metal orders on mobile phones was very large, and metal manufacturers were full of them. Many companies and even the fifth and sixth original orders were able to survive and nourish them. However, good times are not very common. 2016 is the final year for the overall metal fuselage. By 2017, this wave of metal that has been popular for many years has gradually faded!
