5G brings new opportunities to the injection molding industry
In 2019, with the advent of the 5G boom, in addition to the question of whether consumers can increase the experience of use, many people in the plastics industry also questioned whether 5G will benefit from it. The answer is naturally obvious. With the advent of the 5G wave, the metal phone back cover market has further shrunk, because the massive MIMO technology adopted by 5G makes it necessary to add a large number of antennas in the mobile phone, and the metal material will shield and interfere with the signal, so the back cover of the mobile phone goes. Metallization will be the general trend of the 5G era. At present, the back cover of mobile phones is moving from metal to glass, ceramics and plastics. In these three cases, glass and ceramics still have some problems due to cost and process, and plastics become the majors due to their advantages of easy processing and low cost. The back cover making materials that mobile phone manufacturers like.
From the current back cover material of most mobile phones on the market, the metal back cover is gradually disappearing. The main metal part of the fuselage is a metal middle frame, double-sided glass and a small amount of ceramics become the mainstream of the flagship machine. These materials have poor resistance to falling. Basically, they will be equipped with protective shells. These are mainly made of transparent TPU ultra-thin injection molding, and the quantity is increasing rapidly. The middle and low-end models are made of plastic materials, including composite sheet imitation glass, IMT injection molding, and PC injection molding 3D glass. .
Due to the fragile characteristics of the glass and ceramic back cover, many mobile phones using glass and ceramic back covers are inseparable from the protective cover. The material of the protective cover is nothing more than hard plastic such as ABS and PC; TPU soft plastic, leather and some special materials such as carbon fiber and bamboo. At present, most of the protective sleeves on the market are processed by injection molding, such as two-shot injection molding and thin-wall injection molding.
For the plastic back cover of the mobile phone, the use of injection molding is unquestionable. From the initial injection molding of the functional machine era, to the spraying, to the current IMT and back cover PC injection + coating, the plastic casing is on the appearance texture. The experience has a qualitative leap. At the same time, plastics have the characteristics of mature processing technology, low cost and easy mass production, which have been favored by various manufacturers.
The metallization of the back cover of the mobile phone in the 5G era has brought new opportunities to the injection molding industry. At present, many injection molding machine manufacturers have begun to pay attention to this market segment, such as Sumitomo, Fanuc, Arburg, etc. It can be said that the 5G mobile phone material changes, the injection molding industry is a big winner.
In addition to the various injection molding machine manufacturers, some chemical giants are also aiming at this trend. For example, Covestro also launched a solution for the back cover of 5G mobile phones.
In addition to the changes in the materials of wireless devices such as mobile phones, in the 5G era, base station antennas have also undergone considerable changes. In 4G base stations, the antenna elements are generally made of metal. However, 5G will use Massive MIMO technology: a 5G macro base station usually has 3 antenna fans, and each sub-plane has more than 100 antenna elements. In this case, the weight and cost of the metal vibrator is particularly prominent, and plastic can solve this pain point well.
With the advent of the 5G wave, the materials of various mobile communication devices and base station antennas may need to be redefined. More and newer plastic materials will come to our lives with the arrival of this wave, in the 5G era. "Plastic" is still passionate.
