Solution Overview

The hinge system is built using MIM components and high-precision stamped wrap-around structures, achieving machining tolerances within ±0.01 mm. It delivers smooth, consistent motion with an integrated auto-lock when the lid is closed. Designed for long-term reliability, the hinge maintains stable performance with less than ±15% torque decay after 20,000 life-cycle tests.
