Bonded NdFeB magnet is a high-performance permanent magnetic material with high magnetic energy product and coercive force. Its preparation process is very delicate and requires advanced technology and equipment, but as long as you pay attention to details, you can produce high-quality bonded NdFeB magnets.
First, select suitable raw materials. The materials of bonded NdFeB magnets mainly include NdFeB magnetic powder, binder and additives. The quality of these raw materials has a great influence on the performance of the final product. Therefore, when selecting raw materials, pay attention to their quality and ratio.
Secondly, bonding and molding. After mixing NdFeB magnetic powder, binder and additives in a certain proportion, add a certain amount of solvent to make a paste. Then, press this paste into the required shape and use a vibrator to fully vibrate it so that the gap between the punch and the magnetic particles and between the magnetic particles is minimized to ensure the stability of the magnetic properties. Finally, bake the molded blank in a sintering furnace to sinter it into a hard magnet.
Finally, process it. After the magnet is made, it needs to be processed, ground, cut and other processes to increase its smoothness and precision for subsequent assembly and use. Then it is magnetized to give it good magnetic properties.
In short, the production of bonded NdFeB magnets requires strict control of each link. Only by using advanced technology and equipment and paying attention to details in the manufacturing process can we ensure the production of high-quality magnets. A positive attitude and a spirit of excellence will help enterprises continuously improve product quality and market competitiveness.
