It was necessary to manually fill the mold cavity with ferrite powder. This filling method easily caused the powder to fall into the factory.

[0003] Secondly, hard lumps are prone to appear inside the powder. The previous method of dealing with hard lumps requires grinding the ferrite magnetic powder. If these hard lumps are foreign matter such as stones, this will lead to uneven texture after the magnetic ring is formed, which will reduce the product qualification rate. Summary of the invention
