| Abstract: |
| Powder injection molding(PIM) technology has been widely used and developed steadily in the field of bonded permanent magnet ferrite. The medium and low-grade magnetic device products in China have reached the level of developed countries such as Japan, but there is still a certain gap in the consistency and stability of magnetic properties, mechanical properties and dimensional accuracy of high-end products. In this paper, the process characteristics and research progress of injection molding technology for bonded permanent ferrite are reviewed, and the key factors affecting the magnetic properties and mechanical properties of injection-molded bonded permanent ferrite magnets are analyzed and summarized, and the research focus and future development direction of this technology are discussed and prospected. |
