Process maturity Sintered NdFeB round Magnets  

Process maturity Sintered NdFeB round Magnets   Sintered NdFeb circular magnet with mature process is a common type of magnet with high magnetic properties and good magnetization stability. It is made of NdFeb magnetic powder and binder through the sintering process, the shape is usually round.   The preparation process generally includes the following steps:   1. Magnetic powder formula: According to the required magnetic properties and application requirements, choose the appropriate Ndfeb magnetic powder formula. The composition and particle size distribution of magnetic particles have a great influence on the properties of the final product.   2. Mixing and magnetization: Mix the magnetic powder and binder evenly to form a magnetic slurry. Then, the slurry is magnetized by magnetizing equipment to make the magnetic domain of the magnetic powder oriented.   3. Molding: The magnetic paste is injected into the mold, and after shaking and pressing, i…
