Characteristics of NdFeB magnetic plastics

The characteristics of injection-molded NdFeB magnetic plastics and the magnetic properties of injection-molded NdFeB magnetic plastics are directly related to the type of magnetic powder materials added, particle shape, particle size and addition ratio. Due to the addition of matrix resin, Although its magnetic properties are not as good as sintered magnets, it also brings many new features that sintered magnets cannot have. Sintered magnets NdFeB magnetic plastics Maximum magnetic energy product (BH) magnets are low-cost and low-volume production possibilities (sintering process required) large size Poor precision (requires finishing) Brittle size Complex shape can not be completely lightweight / g.cm integrated forming can not be completely radial anisotropic can not be completely continuous maximum use temperature / e recycling can not be magnetic Plastics can cause close attention to production and all parties. An important reason is that it can give full play to the advantages of plastic processing performance. The research on NdFeB magnetic plastics and its injection molding is more efficient than the production of sintered magnets due to injection molding. Low and efficient. It is not necessary to use a magnetic field injection molding machine for producing NdFeB magnetic plastics, and it can be formed by first forming and then magnetizing. One of the main components of magnetic plastics is magnetic powder, and the magnetic powder content is as high as 80
