Magnets are commonly used in our lives. I believe everyone knows about magnets, but there are many categories of magnets, especially strong li magnets. Below we will introduce how the neodymium iron boron strong li magnet is made.
First of all, NdFeB strong li magnet manufacturers understand that it needs to pulverize the alloy containing the necessary materials into particles, gather these particles to form, and then sinter them. Then cut to the required size to complete. Of course, it is not so simple in actual mass production of high-quality NdFeB strong li magnets. Not only must the particles be unified to a size of 3 to 5 μm, but also the uniformity of the shape must be considered, and the heating method during sintering must also be considered, which requires a lot of time to manufacture. "Through the accumulation of a large number of small technologies, we have reached the practical level today" (technical personnel engaged in the development of neodymium magnets). For example, the "molding process in a magnetic field" performed after the alloy is crushed to a thickness of 3 to 5 μm is one of them. This process is to orient the pulverized fine powder (micro magnet). NdFeB manufacturers say that the orientation here refers to unifying the magnetization direction of the fine powder into a certain fixed direction. The higher the orientation, the greater the residual magnetic flux density (indicator of magnetic field strength). When performing this process, the fine powder is first filled in the mold, a strong magnetic field is applied to orient the fine powder, and then the pressure molding process is performed. Among them, the unique feature is that the molded body is gently pressed and molded to the extent that the molded body does not collapse. Because if the pressure is too large, it will disrupt the uniform micro powder orientation. After the above introduction, everyone should understand the production process.
