Compression molding is the most important method to gain high quality bonded NdFeB magnets. The production process is preparation of composite powder, compression molding, coating and magnetizing. Based on test and lot production practice, the important effects of compression molding actions, mould structure and mould material on magnet quality are analyzed. The mold structures for ring-magnet and arc-magnet are fixed. The key techniques that controlling the quality of bonded NdFeB magnets are summarized. |
