                Bonded NdFeB magnet

                Bonded NdFeB magnet is made through "compression molding" or "injection molding" of the mixture of quick-quenched NdFeB magnetic powder and bonding agent. Due to its high accuracy in size, the bonded magnet may be formed into magnetic components of relatively complicated shapes. Also, it features single-time molding and multi-pole orientation. The injection molded magnet has a high mechanical strength and may be molded together with other matching parts.
