Manufacturing Processes in NdFeB Magnet Production
Overview of Sintering and Molding Techniques
The production of NdFeB magnets primarily involves two techniques: sintering and molding. Sintering is a process that involves compacting powdered materials and then heating them to just below their melting point to form solid structures. This method allows for the creation of high-density magnets with excellent magnetic properties.
Molding, on the other hand, is often used for mass production and involves compressing a mixture of neodymium, iron, and boron powder with a resin binder to form a mold. While molding may be less common than sintering, it can lead to varying shapes and sizes while retaining the essential magnetic characteristics.
