| Bonded Magnet: Bonded 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. The injection molded magnet has a high mechanical strength and may be molded together with other matching parts. In all it is produced with high efficiency, stability and repeatability; Magnet and other part may form together in one step; Free choice of magnetizing direction-especially for multi-polar applications; High dimensional accuracy-large quantity applications with minimum post-press machining; Thin-wall ring and complex shape magnets; High resistance to corrosion. Usually, there are bonded NdFeB magnet and bonded SmCo. |
