Special shaped magnets refer specially to the magnets with irregular shape which primarily serve for specific demands. Injection molded magnets are ideally suited for special shaped magnets, but maximum energy product (BH)max of routine isotropic injection NdFeB molded magnets are limited to 60kJ/m3 which cannot satisfy most of special shaped demands. Sintered magnets are generally difficult to achieve net shape at once due to technology limitations in molding and sintering process, thus machining process is essentially impossible to be avoided. Therefore, sintered Neodymium magnets are always criticized by its machinability, but special shaped Neodymium magnets still can be obtained via grinding or wire cutting process, hence its cost and production time are inevitability and significantly higher than conventional block magnets, bar magnets, ring magnets, disc magnets, rod magnets, arc magnets, countersunk magnets, and sphere magnets. Chinese Neodymium magnets industry has already formed a clear division of labor over the years, thus processing enterprises fully learned processing experience from crystal industry and always trying to introduce the latest processing technology. With the process of functional complexity and miniaturization accelerates, consumer electronics exist large demand for special shaped Neodymium magnets.
