Bonded Neodymium magnets are manufactured through the compression process. This process involves mixing neodymium powder with epoxy as a binder and pressing it into a die cavity with no magnetic field, thus making these magnets Isotropic. Pressed parts are then placed into the oven for curing. Compression bonded neodymium magnets are an excellent choice over other magnet types (sintered neodymium, sintered samarium cobalt, and hard ferrites) that have limits to some shapes that compression bonded magnets do not have. With their high energy product reaching up to 12 MGOe it makes them ideal for many applications requiring high magnetic strength and tight tolerances. Since no magnetic field is applied during the compression the finished product can be magnetized in any direction. Having epoxy as a binder in the manufacturing process for compression bonded magnets makes the magnets resistant to most industrial automotive fluids. With relative low tooling cost and quick turnaround compression bonded neodymium magnets are the choice for a wide variety of applications. The final product can be epoxy coated for durability and more resistant to corrosion
Advantages Of Compression Bonded Magnets
1: Higher magnetic strength than injection molded magnet.
2: High corrosion resistance (Epoxy coating, parylene coating) and temperature resistance, the salt spray teasting >72 hours
3: Magnetizing with complex patterns (Multi-poles on OD, ID, end face (axial), radial, helical magnetization......)
4: Higher magnetic property (Br: 3500-8000G, BHmax: 3-12MGOe, Hcj: 4000-17000 Oe
5: Complicated shape
