Abstract

The process of making sintered NdFeB permanent magnets by powder injection molding is reviewed comprehensively in this paper. The influnces of binder,magnetic alignment,molding,debinding and sintering on the products are summarized,and a comparison is made between performance of PIM sintered NdFeB to that made by traditional molding. Finally existing problems are pointed out.
