OPPO Find N6 and the challenge to the “weak point” of foldables

The key to this evolution lies in the second generation Titanium Flexion hinge, which debuts with a manufacturing process based on liquid 3D printing. This technique allows the microscopic irregularities of the support structure to be leveled by applying drops of photopolymer hardened by UV light. The accuracy of the system allows the height variations of the components to be reduced to just 0.05 millimetres, guaranteeing an almost perfectly flat support base. The hinge design has also been optimized with a wider bending radius and a carbon fiber plate, elements that reduce the mechanical stress experienced by the panel during each opening.

The long-term integrity of the surface is entrusted to the Auto-Smoothing Flex Glass, a material designed to counteract “creep”, i.e. the progressive deformation of the internal layers caused by daily use. Compared to traditional solutions, this glass boasts an almost doubled shape recovery capacity and acts as a structural spring that returns the display to its original flatness. Tests conducted by TÜV Rheinland confirmed that the crease depth remains 82% reduced compared to the past even after 600,000 usage cycles, ensuring a smooth viewing experience for the entire life cycle of the smartphone.

In addition to the aesthetic performance, the Find N6 focuses on robustness through the Armor Shield framework. The use of grade 5 titanium, ultra-strong steel and 7000 series aerospace aluminum gives the frame superior stability without adding to the overall weight. Protection is completed by the external Nanocrystal Glass and an aeronautical fiber rear cover, while the triple IP56, IP58 and IP59 certification guarantees resistance to immersion and high-pressure water jets. With these innovations, the foldable sector is moving towards a standard of reliability hitherto reserved exclusively for traditional devices.
