LEC magnetics has available isotropic polymer bonded magnets.


Bonded Neodymium is made by binding rapid-quenching neodymium (NdFeB) powder with a resin. This is then either compression moulded with epoxy or injection moulded with nylon. The resultant magnets have high dimensional accuracy, are less brittle than normal neodymium magnets but are also less powerful. Being less brittle, they can be more easily made into thin walled ring magnets.


Bonded Magnets

Magnets are products that come in a number of shapes and sizes, and the magnets that have really pushed the mold have been bonded magnets. These magnets combine thermoplastic and thermoelastomer resins with magnetic powders in order to create injection molded, flexible magnets. These magnets are great for custom applications where a traditional, solid magnet would not offer the same type of value.


Bonded Neodymium and Ferrite Magnets


Injection molding is not the only process in which bonded magnets are created as bonded magnet manufacturers also utilize the compression bonding process in order to supply customers with a higher magnetic output. The trade-off between the two being that while compression bonded magnets offer a higher magnetic output, they are limited in the shape and sizes whereas injection molded magnets are rather flexible.


These bonded magnets are great for a wide range of applications from sensors to brushless DC motors and just about everything else in between. The two different processes used to create the bonded magnets, injection molding and compression bonding, yield different characteristics when it comes to their final product.ring compression bonded magnet, bonding ndfeb ring magnet, compression molded ring magnet, compression molded neodymium magnet, bonded ndfeb ring magnet, neodymium multipoles bonded ring magnet, black epoxy bonded ring magnets.
