Details
Bonded neodymium magnets are mainly mixed with bonded neodymium magnetic powder and epoxy resin, and pressed and formed by powder metallurgy process. The specific characteristics are as follows:
1. The product has high dimensional accuracy, good consistency and high degree of freedom in shape;
2. The product can be magnetized on any surface, with good magnetic consistency, external charging, internal charging, oblique charging, plane charging, radiation charging, etc;
3. The material utilization rate is high, the product size is guaranteed by the mold, and no post-machining is required;
4. The surface coating has good corrosion resistance, and can meet the long-term use in daily or harsh environment by electrophoresis, spraying, pariline and other processes.
The manufacturing principle and technology of bonded Nd-Fe-B mainly include the preparation of high-performance magnetic powder, the preparation technology of pre-mixed magnetic powder and binder, the molding technology of magnets and the post-processing technology of magnets.
