This product is a bonded NdFeB magnet used in brushless motors. It is an injection-molded magnet made by pressing. Therefore, it has excellent magnetic performance, which is only slightly inferior to sintered samarium cobalt. Bonded NdFeB uses isotropic magnetic powder, which can be magnetized without prior magnetic field alignment, and the direction of magnetization can be unlimited. However, due to process factors, the magnet products still need to be processed by surface coating. In addition, although the temperature resistance and machining properties of the bonded NdFeB magnets are not as good as those of the iron oxide injection magnets, the cost of the bonded NdFeB magnets is lower than that of the iron oxide injection molded magnets in the mold opening and magnetization fixture parts.
The company can provide epoxy resin electrophoresis, acrylic resin electrophoresis, epoxy resin spraying, Teflon spraying, parylene deposition, vacuum dipping and other coating and surface treatment processes, so that the products can meet the long-term work in daily and different use environments. Corrosion resistance, solvent resistance, friction resistance and other requirements. The specific coating requirements can be selected and superimposed according to the requirements of the use environment.
