Abstract

The invention provides a preparation method of an integrally-formed inductor cured by using a magnetic field. The preparation method comprises the following steps: A1, putting a magnetic core wound with a coil into a mold cavity; A2, adding magnetic powder into the mold cavity, carrying out hot press molding, and forming a semi-finished product; and A3, putting the semi-finished product into a magnetic field furnace to be sintered and cured, and forming the integrally-formed inductor. Performance of an inductor product can be adjusted according to requirements, and performance reduction caused by rusting of the inductor product due to solidification in air can be avoided.

Description

technical field [0001] The invention relates to the technical field of inductance preparation, in particular to a method for preparing an integrally formed inductance solidified by a magnetic field. Background technique [0002] In the traditional manufacturing process of integrally formed inductors, the magnetism with coils is put into a heating molding mold for hot pressing, and then it will be cured in nitrogen or air. Curing in air is likely to cause rusting of inductor products. , resulting in a decrease in the performance of the inductance product. However, curing in nitrogen cannot adjust product performance according to demand. Contents of the invention [0003] Based on the above problems, the present invention provides a method for manufacturing an integrally formed inductor using magnetic field curing, aiming to solve the technical problems in the prior art such as the decrease in the performance of the inductor or the inability to adjust the performance of the...
