Bonded NdFeB magnets are produced by binding rapid-quenching Nd-Fe-B powders which is mixed with plastic resin to form a magnet by compression molding with epoxy and injection molding with nylon
1.Bonded NdFeB Magnet
Bonded magnet materials can be created through Injection Molded and
can be made from NdFeB, Strontium Ferrite or a combination of the
two. Bonded magnets that are created through injection molding can
be molded into complex shapes and also molded directly onto
components. Bonded magnets can also be created through the process
of compression bonding which offer higher magnetic output but are
limited to simpler geometries than Injection Molded materials.
Compression Bonded magnets can be made from either NdFeB or SmCo
powders.
2.Injection Moulded
Binder Types / Nylon / PPS / Polyamide.
Temperature Range -40c 180c
Very Tight tolerances off tool ( 0.002 -0.003 Typical )
Very good mechanical strength
3.Compression Bonded
Higher Magnetic Strength due to higher magnetic particle density.
Epoxy Binder / Resistant to normal industrial solvents and
automotive fluids
Epoxy Coat after manufacturing to prevent oxidation
Temperature Range -40c ~165c
"Tight" tolerances off tool
Good mechanical strength
Typical Bonded Magnet Applications:
Sensors
Brushless DC Motors
Household Appliances
Compressor
4.Bonded NdFeb Magnet application
