< p > < strong > Reference News Network reported on Jan. 10 < / strong > Japanese media said that the battle for raw materials for 5G smartphones is becoming more and more fierce. The material used to make 5G mobile phones will no longer be metal, but glass and resin, which have less impact on radio signals. The giants of raw material enterprises such as glass manufacturers have been boiling for the arrival of this new round of demand, but the enterprises such as Fanaco, which originally mainly produces metal fuselage processing equipment, have encountered adverse wind. Companies are also competing for new technologies to ensure adequate orders.

According to the report of Japan Economic News on Jan. 9, the high transmission rate is the characteristic of 5G communication, and the maximum speed can reach 10GB per second, which is about 100 times of the current 4G network. It is expected that the United States and South Korea will officially launch 5G commercial services in 2019. LG Electronics in Korea and Huawei Technologies in China are both developing smartphones suitable for 5G standard.

reports that the change of mobile phone body materials has attracted the attention of smartphone-related manufacturing industry. Always, aluminum and other metal materials have been used in the body of smart phones. Although the quality is higher than that of plastics, there are also weaknesses that hinder the transmission of radio signals. A mobile phone manufacturer said that even in the current 4G network, if part of the fuselage material is replaced by glass or resin, it can greatly improve transmission speed. The report

points out that the radio frequency used in 5G network is much higher than that of the existing communication network, but the transmission quality may also be affected by the fuselage material. And glass manufacturers have found business opportunities.

reports that Corning, a giant specialty glass manufacturer, has developed a non-fragile fuselage backplane made of gorilla glass. Compared with aluminium and stainless steel, high frequency radio waves are easier to pass through glass materials and improve the efficiency of wireless charging. Apple's iPhone X and other models have adopted glass backplanes. Corning is confident that there are many business negotiations for 5G mobile phones. < p > < p > < p > Diren Company has produced a mobile phone backplane made of aramid fiber reinforced plastics. There have also been precedents for backboards made of resins, but Diren's product is lighter, more impact-resistant and has been used on Sharp's new smartphone AQUOS Zero.

reported that compared with material manufacturers excited by 5G demand, those who have been engaged in manufacturing metal fuselage processing equipment are somewhat depressed.

Japan's Fanaco Electrical and Mechanical Co. and Brothers Industrial Co. mainly manufacture metal processing machine tools. They received thousands of metal processing machine tools ordered by Chinese electronics manufacturing service companies for Smartphone modification at a time. According to the statistics of Japan Machine Tool Industry Association, orders from China in 2017 amounted to 146.2 billion yen ($1.3 billion), nearly three times as much as in 2016. Most of the demand comes from the need of smartphone modification.

reports that even if the 5G smartphone fuselage is made of glass, the fuselage frame will still be made of metal. So the demand for machine tools will not disappear, but Saito Keshi, Nomura Securities Stock Research Minister, believes that the demand from smartphones will be reduced to 70% of the current level in the future, and if resin materials are used, the fuselage will no longer use metal, and the demand for machine tools may further decline.

In order to compensate for the decline in sales, Fanaco has turned its attention to injection moulding machines. The company's market share of precision injection moulding machine for IT industry is also high.

Brother Industries, which takes on a large number of orders for Smartphone metal processing machine tools, believes that even in the 5G era, demand will not fall sharply. However, it has recently begun to shift the focus of production to the general construction machinery and the processing machine tools needed for the production of automobiles.

reports that what kind of materials will become the mainstream of 5G mobile phones will also be affected by consumer preferences. Enterprises will also pay close attention to the mobile phone manufacturers'trends and improve their own response system.

November 27, 2018, Sharp demonstrated the use of reinforced plastics containing aramid fibers as the backplane of smartphone AQUOS zero. (Yahoo News Website, USA)
