The characteristics of the hinge of the mobile phone case mainly include high durability, portability, precision, and innovation. ‌

High durability: As a key functional component of foldable screen phones, the hinge hinge needs to have a lifespan of at least 100000 opening and closing cycles, as well as the characteristics of light weight, small size, and strong stability. This requires that the hinge of the shaft meet high standards in design and material selection to ensure long-term service life and stability. ‌

Lightweight: Due to the modern demand for portability, hinge hinges need to be as lightweight as possible in order to reduce the overall weight and volume of the phone when folded. This requires precise manufacturing processes and materials with lightweight characteristics. ‌

Precision: The design and manufacturing of hinge hinges require extremely high precision, including strict control of rotational accuracy and friction coefficient. In addition, the hinge of the shaft also needs to provide certain damping and protection to ensure uniform force during the opening and closing process, while protecting the screen from damage when subjected to external impacts. ‌

Innovation: With the development of technology, the design of hinge hinges is constantly innovating to adapt to new technologies and materials. For example, by adopting spiral design scheme, armored aluminum material, waterproof hinge design, and dust-proof fiber technology, these innovations not only improve the performance of hinge hinge, but also enhance the overall user experience of foldable screen phones.
