Shaft application case

Skills Requirement
1. There is no obvious rust in the salt spray test for 8H;
2. There is no obvious crush or scratch on the appearance;
3. The finished rotating product of Stoppable Shaft MIM Parts cannot have a big abnormal sound;

Common problems and precautions of the shaft
1. Damping shaft: The shaft of a notebook computer usually requires the opening angle of the screen to achieve any stop to meet our daily usage habits. Its original performance is to achieve angular stop through the friction force of the gasket between the rotating shafts, which is often referred to as the damping shaft.
2. Lifespan problem: In addition to structural damage and fracture, damage to the notebook shaft is often referred to as a lifespan problem. As the number of opening and closing increases, the friction will become smaller and smaller.
3. Maintenance issues: After understanding the structural principle of the notebook computer shaft, take care of it in daily use and do not open and close frequently.
