Abstract

The invention relates to an inductor production method. The method comprises the following steps of: putting powder into a storage tank; putting a coil into a mold cavity of a mold, and completely or partially putting two terminals of the coil outside the mold cavity; adjusting a capacity of a quantification hole through adjusting an extension amount about extending into the quantification hole by a quantification rod, and guiding the powder into the quantification hole to carry out quantification; putting the quantified powder into the mold cavity and sealing the mold cavity; and carrying out heating and extrusion forming on the powder in the mold cavity. According to the inductor production method, the powder is quantified by adoption of the quantification hole according to the powder amount required by the inductor, and then the quantified powder is put into the mold cavity to undergo extrusion forming. The quantification rod extends into the quantification hole to adjust the capacity of the quantification hole, so that the quantification can be conveniently adjusted according to the required powder amount, and graded quantified addition can be further carried out. An inductor production process is capable of changing the powder adding amount according to a practical using amount, so that the application range is improved.

Description

technical field [0001] The invention relates to the technical field of powder metallurgy, in particular to an inductor production method. Background technique [0002] Powder metallurgy is a process technology that uses metal powder or a mixture of metal powder and non-metal powder as a raw material, after compression molding and sintering, to manufacture metal materials, composite materials and various types of products. The purpose of forming is to obtain a compact with a certain shape, size, density and strength. At present, the commonly used molding method of powder metallurgy is compression molding, that is, the powder powder is put into the mold cavity at the molding temperature, and then the mold is closed and pressed to form it. [0003] According to the temperature during molding, it is divided into cold pressing (room temperature), warm pressing (100-300°C) and hot pressing (>300°C). For the production of inductors, the warm pressing process is often used. Suc...
