Bonded NdFeB magnet includes compression moulding NdFeB magnet and injection moulding NdFeB magnet. Due to its high accuracy in size, the bonded NdFeB magnet may be formed into magnetic components of relatively complicated shapes. Also, it features single-time moulding and multi-pole orientation. The injection molded NdFeB magnet has a high mechanical strength and may be molded together with other matching parts. |
