Description

Technical Field

[0002] Magnetic materials are widely used in the electronics, electrical and automotive industries, especially in the fields of energy, communications, automation, etc. Common magnetic materials include ferrite, neodymium iron boron, aluminum nickel cobalt, etc. They have good magnetic permeability, stable magnetic properties and high resistance to saturation magnetic field strength.

[0003] Pressing and molding magnetic material powder is one of the common processes for manufacturing magnetic components.

[0004] The existing magnetic material powder forming device has the following defects under actual use conditions:

[0005] It is necessary to use an electronic balance or automatic weighing equipment to accurately weigh the magnetic material powder in advance to ensure that the amount of powder injected into the mold is consistent with the required amount; the step of weighing the magnetic material powder is added, resulting in reduced production efficiency.

[0006] If a structure capable of quickly and quantitatively measuring the amount of magnetic material powder can be built into the existing magnetic material powder forming device, the step of weighing the magnetic material powder in advance can be omitted, which will undoubtedly improve production efficiency.
