Injection Molded Bonded NdFeB Magnet bonded neodymium magnets ring magnet Epoxy coating

Product Description

Bonded NdFeB magnets are strong magnets which are used for various applications. They are manufactured by binding rapid-quenching NdFeB powde mixed with resin to form a magnet by compression molding with epoxy or infection molding with nylon. The latter technique is particular effective in large volume production, though the magnetic value of products is lower than those made with compression molding because of their relatively lower density. Bonded NdFeB is easily machined. Coolants must be used while machining this material in order to avoid spontaneous combustion of powder. Machining this material removes a layer of protective coating, and re-coating for corrosion resistance may be necessary. Various shapes of high dimensional accuracy can be produced without further processing. Epoxy coating is mostly common used for bonded NdFeB magnets, nickel-plating is also used to prevent corrosion.

Isotropic bonded NdFeB materials can be magnetized in any direction, or with multiple poles. Special magnetizing fixtures are required in order to achieve multiple pole magnetization. isotropic resin bonded Neodymium-Iron-Boron material offers a high energy product with an exceptional resistance to demagnetisation. Capable of operating up to **0ºC. Ring magnets may be machined from discs. Being isotropic, most shapes can be magnetised in any direction. Discs or rings may have either axial or diametric poles. Minimum field strength to magnetise to saturation is ***0kA/m (****0 0e). Such multipole fixtures may cost several thousands of dollars depending on design complexity and production rate requirements.

We manufacture rare earth bonded NdFeb magnet (bonded neodymium magnets) by using both injection and compression moulding techniques, which particularly suit for high volumn production of a wide variety of shapes and size ranges. Our bonded ndfeb magnets are high energy products ranges from 4.0 MGOe to *2.0 MGOe. Precise dimensional control is achieved in both processed and usually the component does not require futher machining.



Injection moulded NdFeB magnets do not normally require coating due to better corrosion resistance, however coating is recommended for compression moulded NdFeB. Epoxy coating or nickel plating is available for surface treatment to against corrosion.
