STUDY ON THE MOLDING TECHNOLOGY OF BONDED NDFEB MAGNETS FROM INJECTION MOLDING

摘要：

For the composite powders with different NdFeB powder content ,the effect of processing parameters including injection temperature,injection pressure,holding pressure and injection velocity on the sizes and properties of injection molded bonded NdFeB magnet was investigated,and the reasons of effect were also analyzed.The injection temperature and injection pressure have the greatest impact on the performance.The injection molding bonded NdFeB magnet with high performance is obtained with magnetic properties Br=0.539T,Hcb=345.37kA/m,Hci= 681.02kA/m, (BH)max=47.37kJ/m3 and density 5.07g/cm3 respectively.
