Permanent Bonded Injection Moulding Neodymium magnet for automatic door
 

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.

Injection Molded:Binder Types / Nylon / PPS / Polyamide.Temperature Range -40c 180cVery Tight tolerances off tool ( 0.002 -0.003 Typical )Very good mechanical strengthCompression Bonded:Higher Magnetic Strength due to higher magnetic particle density.Epoxy Binder / Resistant to normal industrial solvents and automotive fluidsEpoxy Coat after manufacturing to prevent oxidationTemperature Range -40c 165c"Tight" tolerances off toolGood mechanical strengthTypical Bonded Magnet Applications:SensorsBrushless DC MotorsHousehold AppliancesCompressorautomatic doorGeneral Bonded Magnet Applications:Materials are isotropic and can be magnetized in any directionWide range of existing tool sizes are available in rings, discs and rectanglesExsisting Multipole magnetizing fixtures for quick prototypingEasily machinedExisting Multipole rings simplify assembly verse arc sepments
