Since the birth of the iQOO brand, its generations of mobile phones have conveyed a unique product concept - a sense of speed.
In addition to emphasizing the strength of the core performance of the mobile phone, this sense of speed is also reflected in iQOO's pursuit of product industrial design, such as the rally orange color scheme with a sense of racing speed, the three-color legendary version designed in conjunction with BMW, and the track version that restores the texture of the kivlar with the texture of the plain leather material to restore the interior of the car.
iQOO has always wanted to give products a fast enough performance experience and a unified visual appearance. This time, iQOO broke through the process and manufacturing problems, applying real Kevra aramid fibers to the 3D back cover of the phone, bringing the iQOO 9 Pro Track Edition clad in Kevra armor.
Speaking of Kevlar, I think everyone will not be unfamiliar, before some manufacturers used it as the back cover material of flagship mobile phones. Kevlar is a new type of aramid fiber composite material, because of its low density, high strength, good toughness and other characteristics, it is widely used in military, racing, safety protection, and even aerospace and other key areas, Apollo 16 moon landing spacesuit has a credit from Kevlar.
When this new type of high-tech synthetic fiber is applied to the back cover of the mobile phone, it bursts out many advantages: Kevra's excellent strength and toughness make the mobile phone have better scratch resistance and fall impact resistance; and this material is an insulator, which will not interfere with the signal like carbon fiber or metal; and because of its low density characteristics, it is easier to do light and thin than the glass and plain leather materials commonly used in flagship mobile phones. These advantages are in line with iQOO's design pursuit of powerful performance and speed.
In the past, mobile phones that used Kevlar as a back cover material were generally flat 2D back covers, and when mobile phones entered the era of 3D curved back covers, they rarely saw the figure of this high-end material. In order to overcome these difficulties, iQOO invested millions of yuan in research and development costs, and polished a total of 24,800 back cover hands before and after, before finally presenting the iQOO 9 Pro track version of this unique sense of toughness exclusive to Kevlar's thinness.
In order to show enough refinement in the back cover, the iQOO 9 Pro Track Edition uses a finer 600D Kevlar aramid fiber for precise texture weaving, resulting in a finer texture effect and a more delicate feel.
In order to ensure the fire resistance and curved shape of the back cover, iQOO 9 Pro Track Edition first pre-immersed the Kevlar material with a special thermoset resin, then the three layers of Kevlar material were superimposed by hot pressing, and finally through the high-temperature vulcanization process under vacuum, the Kevlar material was 3D formed. iQOO also added a layer of matte UV paint to the back cover that enhances hydrophobicity, which is less likely to leave traces whether it is fingerprints or hand sweat, making this delicate Kevlar back cover more durable.
High strength and toughness are the two major advantages of Kevlar, but they bring processing difficulties. To this end, iQOO uses a laser process to cut the Kevlar material to ensure that the curved edges of the 3D back cover are smooth enough. In order to eliminate the fine burrs left behind, iQOO 9 Pro Track Edition through the innovative micro-hemming process, the cut Kevlar back cover edge wrapped with PC resin, so that the curved edge is smoother and burr-free, and then through the gradient spraying to make the Kevlar back cover to the fuselage frame to achieve a smoother look and feel transition, improve the sense of unity of the whole machine.
According to the official introduction, after seven sprays, seven high-temperature treatments and two polishing processes, a total of sixteen process treatments, this Kevlar back cover can be finally formed. Its weight, only 12.34g, achieves a light texture while ensuring strong and strong characteristics, which is also the most expensive iQOO mobile phone back cover at present.
The iQOO 9 Pro Track Edition retains the unique panoramic porthole design of the iQOO 9 series. This panoramic porthole, which is born from the racing sunroof, makes the iQOO 9 Pro Track Edition have the design recognition and visual impact, through the integrated large module design, so that the back cover appears simple and symmetrical and orderly. The black tone of the entire module echoes the woven texture of Kevlar material, making the iQOO 9 Pro Track Edition exude a calm sense of business.
This huge panoramic porthole, the entire metal module is made of the same space-grade aluminum alloy, after multiple milling, sandblasting and oxidation processes, giving the underlying metal bracket, metal edge and camera decoration circle different colors and textures. The two main decorative rings also milled a circle of highlights, which is more delicate.
Panoramic portholes not only have a sense of design, but also take into account functionality and practicality. Metal components and porthole lenses are designed with progressive paragraph differences, while reducing the abruptness caused by the protrusion of the module, the large area of metal materials brings a good heat dissipation effect, and the multi-layered paragraph design makes the space inside the fuselage more abundant, and can further improve the heat dissipation conditions of the fuselage.
In terms of hardware configuration, the iQOO 9 Pro Track Edition is a proper flagship level: the top Samsung E5 material 2K+ OLED screen, Snapdragon 8Gen1 processor + overclocking version UFS 3.1, the first GN5 sensor dual main camera camera, first-class 120W wired fast charge and 50W wireless fast charge. Not only the pursuit of speed aesthetics in the design, iQOO 9 Pro Track Edition is also fast and full of blood in terms of hardware specifications.
Overall, after overcoming the technical difficulties, iQOO finally applied the Kevlar material to the 3D back cover, a new material that gives the iQOO 9 Pro Track Edition a different speed aesthetic than before. This difference, which comes from the avant-garde of high-tech materials, is only 12.34g of lightness, and it is the unique tough texture of Kevlar. And these are iQOO's latest interpretations of the design language of speed aesthetics.
