ABOUT BONDED NEODYMIUM / CUSTOM MOLDED MAGNETS

Bonded magnet of ours can be divided into Compression Molding NdFeB, Injection Molding NdFeB and Injection Molding Ferrite according to the processing methods and materials. It is often used to substantially reduce the size of designs that used ceramic magnet materials. Significant size reductions can be achieved because this kind of material is approximately 3 times stronger than ceramic magnet material. In addition, since the material is isotropic, it can be magnetized multi-polar, such as a N-S-N-S pattern on the outer diameter of a ring. They can be found in a wide variety of applications including office automation equipments, electric fitting devices, miro-driving motors.ect.
Unlike sintered magnet, bonded magnet is a special form of NdFeB or ferrite powder blended with a plastic carrier material. They are depressed and heated to solid. Parts made in this way can be of complex shapes and come off the tool with tight tolerances. No need for further mechanical machining. Another benefit of the injection molding process is that magnet material can be directly molded into, onto, or against other assembly components eliminating subsequent assembly steps.
