Flat and smooth folding performance of zirconium-based liquid metal folding screen mobile phone by going up one flight of stairs.
It is reported that leading domestic mobile phone manufacturers have used liquid metal structural parts for hinges of several generations of folding screen mobile phones. The use of liquid metal material makes the folding screen mobile phone produced by it not only have a smaller bending radius, but also be extremely thin and have a flatter screen. The company's folding screen mobile phone can achieve better flatness, which is closely related to the application of zirconium-based liquid metal hinge, because its new generation of water drop hinge assembles all MIM and high-strength steel structure parts on the amorphous (liquid metal) spindle, which requires very high strength, accuracy and wear resistance of the spindle, making the accuracy requirement of a spindle structure part near 10 reach the top level in the processing industry. It can be said that the zirconium-based liquid metal rotating shaft structure has made an indispensable contribution to the smooth folding of the folding screen mobile phone.
Public information shows that liquid metal material is a kind of metal material with unique amorphous molecular structure and low melting point. Its strength is more than 65,438+00 times that of magnesium-aluminum alloy, more than 2 times that of stainless steel and titanium alloy, its hardness is also more than 65,438+00 times that of magnesium-aluminum alloy and more than 65,438+0.5 times that of stainless steel and titanium alloy, and it also has great advantages in magnetism, corrosion resistance and wear resistance. In addition, liquid metal has a great advantage that it has excellent formability after melting, which makes its casting process more similar to plastic than nonmetal, and can be made into various forms of precision products more conveniently.
When applied to the hinge of folding screen mobile phone, the zirconium-based liquid metal folding screen mobile phone hinge can meet the strength and accuracy requirements of hinge supporting folding screen mobile phone under the condition of small thickness. At the same time, due to the excellent elastic deformation ability of liquid metal itself, the fatigue performance of the product is far superior to other materials, which can greatly improve the fall resistance, wear resistance and bending life of the folding screen mobile phone, and also make the folding screen mobile phone more advantageous in flatness and aesthetics.
Yi 'an Technology is one of the largest liquid metal manufacturers in the world.
The key components of folding screen mobile phone include flexible display screen, hinge, protective cover, touch conductive material, structural design and so on. Among them, flexible display screen and hinge are considered to be the two most critical technologies different from traditional mobile phones. The hinge of the folding screen shaft is composed of multiple interlocking gears, which can provide accurate motion control and play a key role in the seamless fitting of the folding intelligent terminal. Technically, the hinge of the folding screen mobile phone is integrated by multiple parts, which requires more than ten kinds of metal parts and MIM, stamping, liquid metal and other processes. This process is extremely complicated and often requires the cooperation of multiple suppliers.
From the specific division of labor, the overall design of hinges is generally completed by mobile phone manufacturers, and structural parts are developed and manufactured by different upstream suppliers according to needs. For example, the liquid metal structural parts of H Company's folding screen mobile phone hinges are all made by A-share listed company Yi 'an Technology (300328. SZ), and the MIM part is made by Jingyan Technology and other companies (300709. SZ)。
It is worth mentioning that compared with other parts, the technological threshold of liquid metal is extremely high. At present, there are few domestic large-scale production enterprises, only a few enterprises such as Yi 'an Technology and Changzhou Shijing. Yi 'an Technology is one of the leading enterprises in liquid metal industrialization in China and even the world. As early as 10 years ago, the company began to focus on the research and development and industrialization of liquid metal, with independent intellectual property rights in liquid metal composition, molding technology and equipment, and the largest zirconium-based liquid metal production line in China. Its products have been widely used in automobiles, consumer electronics, watches, medical devices, sporting goods and many other fields. In the field of folding screen mobile phone hinges, Yi 'an Technology is one of the few enterprises in the world that can develop and produce zirconium-based liquid metal folding screen hinges on a large scale, and has provided several generations of liquid metal hinges for H Company, the leading domestic folding screen mobile phone manufacturer. In addition to H company, Yi 'an Technology is also cooperating with many mobile phone companies on hinges. Interoperability information shows that Yi 'an Technology has cooperated with five customers on liquid metal hinges, and some customers are jointly developing products.
The agency predicts that the folding screen mobile phone market will grow at a high speed.
According to the research report of CITIC Securities, the global shipment of folding screen mobile phones will increase from 2018198,000 units to 2.8 million units in 2020, and it is estimated that 202 188% will reach 7.5 million units. Then, with the maturity of technology and the reduction of cost, it will be folded globally in 2025.
In terms of brands, Samsung and Huawei, as the dominant players in the global folding screen field at present, are still expected to perform strongly in the future. However, with the efforts of new brands such as Xiaomi, OPPO, VIVO and Honor in the field of folding screens, the market competition may be further intensified in the future, but more intense competition will also accelerate the overall growth of the folding screen mobile phone market.
CITIC Securities believes that although the industry still faces development difficulties such as structural design, flexible modules, hinges and product ecology, the subsequent iterative upgrading will accelerate, so it is optimistic about the overall growth space of the industry and related industrial chain companies.
