Advanced cover glass is an important part of 5G applications
In order to meet the era of high-speed mobile Internet, Apple iPhones have once again introduced the double-sided glass body as a standard feature in the entire series of products. Unlike Apple ’s mobile phone, which only used a double-sided glass body as a pure glass appearance art display, Apple ’s double-sided glass body design this time is to make full use of the artistic expression of glass materials, and also to meet the high speed High-speed wireless connection technology in the era of the mobile Internet has become widespread.
From the industry definition of high-speed mobile Internet technology applications represented by 5G network technology, in addition to the wireless network data transmission speed to adapt to long-distance ultra-high-definition real-time, real-time video transmission, other near-field wireless communication technologies such as NFC Wireless charging and wireless data transmission also need to meet the real-time transmission of large-capacity shared data to ensure that the user experience of the entire network can meet the 5G network technology standard requirements.
With the rapid improvement of RF performance requirements for various wireless transmissions of smart phones, metallic materials that are not friendly to electromagnetic wave signals have already faced bottlenecks at the end of the 4G era. Today, the 5G era is fast approaching. The large and complex RF front-end and antenna modules of 5G mobile phones, as well as the characteristics of the 5G network signal itself, have improved the RF performance of the device to a position higher than the computing performance. To solve this series of problems It is very important to solve the problem of electromagnetic shielding of the mobile phone casing. As the most mature technology and functional materials for mass production in the smart phone industry, advanced cover glass has also become one of the best solutions.
Hungry for high-end cover glass production under huge market demand
However, electronic glass represented by advanced cover glass is still an emerging market area in the entire glass industry. It requires deep technical accumulation and production capacity operation experience to control, and it has inherited the traditional glass industry investment scale. Large, long capacity construction, high operating costs.
Therefore, as the global electronics manufacturing center and the electronic consumer market center migrate to China, the demand for the electronic glass market as an upstream core material has also been concentrated in China, bringing more markets to the domestic electronic glass industry. opportunity.
The high-end cover glass for smart phones belongs to high-aluminum-silicon glass, which is a high-end special functional material with high strength, scratch resistance, and impact resistance. It can be widely used not only in electronic information products, but also for automobiles and high-speed railways. , Aviation and other industries and defense equipment to provide key basic materials. In the "Instruction Catalogue for the First Batch of Application Demonstrations of Key New Materials (2018 Edition)" issued by the Ministry of Industry and Information Technology, "High Aluminium Silicate Cover Glass" is listed among them.
As a key strategic material for the electronic information display industry, for a long time, high-end cover glass in the Chinese market has been monopolized by American, Japanese, and German companies, resulting in the lack of key links in the Chinese electronic information display industry, the industry scale is limited, and electronic information display products. The price has remained high for many years, which has severely affected and restricted the development of China's information display industry and national strategic security.
According to statistics from Li Xing's statistics from the industry, currently the company with the largest production capacity of high-end cover glass in the world is the United States Corning Corporation, whose production capacity can meet the industry's installed demand for 350 to 400 million double-sided glass body mobile phones. The production capacity is almost Apple iPhones and Samsung's high-end phones are monopolized, and other terminal brands can only allocate a small amount of capacity in their own high-end models.
However, several other high-end cover glass manufacturers on the market have limited production lines and can only produce as many high-end cover glass as possible to meet the market demand while satisfying other high-end electronic glass production capacity.
Therefore, other terminal brand customers on the market can only adopt optional methods for the glass material of the rear battery cover on the basis of maintaining the production capacity of the front display cover glass of their products. Many end-brand customers cannot obtain high-end cover glass materials, and can only allow cover manufacturers to produce glass-like composite plastic cover industries to meet product shipment needs.
At present, the industry is only in the initial stage of commercialization of 5G. There are still relatively few terminal products that truly support 5G. The product arrangement for the design of double-sided glass bodies can also be adjusted manually. But as the popularity of 5G technology accelerates, the terminal market's immediate need for double-sided glass body designs is imminent.
Especially in China, a consumer electronics manufacturing center, high-end cover glass materials are not only an important link in determining the technological realization and technical strength of domestic brands '5G products, but also an important guarantee for the security of production capacity supply of Chinese domestic brands' 5G products.
CZQB electronic glass technology group helps China's electronics manufacturing industry industry chain security
As the leader of China's electronic glass and photovoltaic glass industry, CZQB Group is one of China's most important float glass manufacturers, with daily shipments reaching 15,000 tons and daily melting volumes up to 177,000 tons. Occupy 12% of domestic float capacity and market share. In response to the requirements of Chinese terminal brand manufacturers, in order to ensure the safety of the supply of high-end cover glass in China, CZQB Group actively responded to the market and kept pace with the electronic glass business to Liling CZQB, the industry's earliest float glass production base. bear.
CZQB Group established CZQB Electronic Glass Co., Ltd. in Zhuzhou base last year. And as early as last September, CZQB Group started production of a 350-ton ultra-white glass production line at the base for the consumer electronics market. After receiving market demand, CZQB analyzed the technical requirements of high-end cover glass for end-brand customers in the Chinese market, adjusted the float glass electronic glass mass production formula for new high-end cover glass according to industry applications, and successfully launched the industry demand High aluminum silicon cover glass products.
In order to meet the strategic deployment of 5G products for terminal brands in the Chinese market, CZQB has independently designed high-end cover glass production capacity from the existing electronic glass production line at the request of customers, and has redesigned and built a mass production line for high-end cover glass. With a designed production capacity of 6-8 million square meters, it can meet the needs of end-brand customers with more than 400 million high-end cover glass installations.
July 20 will be an important turning point for China's high-end cover glass industry. The mass production line for the production of float high-end cover glass designed and built by CZQB will be officially ignited. CZQB will also become the main supply of high-end cover glass materials in the global market. Manufacturers will continue to make efforts to ensure the supply security of China's electronics manufacturing industry chain.
CZQB Group has successfully operated 26 production lines in the global market, as well as this high-alumina electronic glass production line that will start operation immediately. In China and Southeast Asia, there are production capacity bases, and product terminals serve direct and indirect services in more than 100 countries and regions. The terminal brand customers stated that CZQB Group's accumulation of float glass production technology, support from a large float production technology team, and customer service strength relying on the layout of global production bases, etc. are the collective choice of terminal brands for CZQB Group An important guarantee for the production capacity cooperation of float high-end cover glass.
