Uncovering the secrets of Xiaomi MIX Fold 3: the innovative keel hinge brings a unique hand-feeling and cross-generation design

Xiaomi released its new foldable phone MIX Fold 3 on August 12. This phone introduced an innovative design called "keel hinge" for the first time, providing users with unprecedented screen protection and usage experience

Xiaomi founder Lei Jun introduced an epoch-making design that has attracted widespread attention, namely the keel hinge. Lei Jun said that this breakthrough technology brings new screen protection to mobile phones through 14 movable joints. Compared with the traditional hinge design, users will enjoy a more durable and stable use experience

According to reports, Xiaomi is facing unprecedented challenges in implementing this newly designed hinge technology. In order to meet this challenge, Xiaomi first used a new super steel material as a key component. Its strength reached an astonishing 1800 MPa, which is equivalent to being able to carry a mass of 72 tons on an area of ​​​​4 square centimeters. In addition, in order to ensure the opening and closing feel, Xiaomi has also innovatively applied highly wear-resistant carbon ceramic steel. The wear resistance of this material is comparable to sports car-grade brake pads and is four times the material used in folding mobile phones currently on the market.

Xiaomi MIX Fold 3’s newly designed structure and materials bring an amazing opening and closing experience. Users can freely hover at angles from 45 degrees to 135 degrees, giving greater flexibility and making it more convenient whether watching movies, video conferencing or taking photos. In addition, the keel hinge has been introduced, making the folding life longer, the screen flatter, and taking up less space

Xiaomi MIX Fold 3 will be officially released on August 16, and users will have the opportunity to experience this revolution in person folding phone design. Xiaomi's keel hinge technology not only achieves a breakthrough, but also brings a more excellent user experience to users, creating a new era of folding mobile phone design
