There are two main Bonded NdFeB Magnet manufacturing methods:
ï‚·Bonded Injection Plastic Moulding NdFeB
ï‚·Bonded Compression Moulding Ndfeb
Bonded Compression Moulding NeFeB Magnets ( called Compression Bonded Magnets) are made by using many isotropic Neodymium, Iron, Boron materials, as well as crushed and powdered Samarium and Cobalt ingredients.Combinations of different elemetal grades are used to creat specific magnetic properties. Compression Bonded Magnets offer higher magnetic strength than Injection Plastic moulded magnets. Although Compression Bonded Magnets have higher magnetic particle density, ther are limeted to simple geometric shapes due to the compaction process. The epoxy is used to protect the magnet surface from industrial solvent and automotive fluids. The normal applications of the magnets range from -40℃ to 150℃.
The advantages of Compression Bonded Magnets:
1. High quantity and even volume manufaturing, with up to millions of pieces per year
2. Single-time moulding and multi-poles orientation.
3. Effective surface treatment to prevent corrosion. The product is coated with epoxy resin to be protect the surface smoothing.
4. Excellent magnetic properties. The energy of Compression Bonded Magnets is 3 times as high as anisotropic ferrite magnets.
Application of Compression Bonded magnets:
•Mini motors
•Automatic contolling devices
•Sensors
•Drivers
•Telecom
