Multipole Ring Bonded Epoxy Resin Binder Magnet BNP-2 China bonded ndfeb magnets neodymium magnets manufacturer & supplier – 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. Due to their complex geometries availability, high dimensional precision, uniform magnetic properties, diverse magnetization patterns, good corrosion resistance and mechanic properties, bonded NdFeB magnets are widely applied in spindle motors, micro motors, direct current (DC) motors, synchronous motors, power tools, magnetic rollers, Hall effect sensors, etc.

MPCO has the ability to produce compression bonded NdfeB magnets that exhibit the very best magnetic and mechanical properties.
We can achieve densities well beyond the industry norm and this helps our customers achieve the very best performance and durability in high technology motor and other applications. In some cases this has allowed clients to replace the more expensive sintered NdFeB permanent magnets. BNP-11 Diametrically Magnetized Radial Ring Magnet For DC Motor
MPCO is also on the forefront of application development for injection moulded isotropic and anisotropic permanent magnets. Air Cleaner Air Purifier Bonded Neodymium Hot Deformed Magnet
Currently our production quantities for these types of component are in excess of 10 million parts annually.
