Bonded NdFeB Multipole Magnetic Sensor Ring, Injection molded NdFeB magnets, polyer binder isotropic ring magnets for sensor, epoxy, Nylon/polyamide (PA), polyphenylene sulfide (PPS) 8-poles 12-poles Bonded NdFeB Multipole Ring
Bonded NdFeB Multipole Magnetic Sensor Ring Basic Info:
Injection molded magnets are produced by injecting the special pellets into the mold. This kind of magnet covers a wide range of characteristics as bonded magnets, including heat resistance and higher magnetic properties. Injection molding technique offers flexible shape design as well as over-molding and insert-molding with other parts for easy assemblies. Bonded Injection Moulding Ferrite Magnet for Sensor
The advantage of injection molded magnets
For this kind of isotropic magnets, any magnetization direction can be applied. This is a congenital advantage to manufacture the multi-polar magnets.
Injection molded magnets have excellent dimensional accuracy and serial productivity.
Thin wall thickness and complex shape can be manufactured.
Over-molding and insert-molding with other parts, like back yoke, hub, shaft is readily available, as well as injection other polymer parts can be incorporated.
The polyer binders’s volume fraction of injection molded magnets higher than the compression molded magnets. It will provide adequate protection against corrosion without coating in most applications.
Bonded NdFeB magnets, i.e. Bonded neodymium iron boron magnets, are those permanent magnetic materials made of rapid quenched NdFeB magnetic powders combined with resin binders (epoxy, Nylon/polyamide (PA), polyphenylene sulfide (PPS), etc). They are manufactured through a bonded process (compression, injection, extrusion or calendaring molding), so it is available to obtain complex geometries with high dimensional precision. Controlling the performance and proportion of NdFeB magnetic powders, it is able to adjust the magnets’ magnetic properties in a continuous range.
