Bonded NdFeB Magnets

Bonded NdFeB magnets
Bonded NdFeB magnets are manufactured by binding rapid-quenching NdFeB powder. The powder is 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. Various shapes of high dimensional accuracy can be produced without further processing. Surface is treated by epoxy coating or nickel-plating to prevent corrosion

Advantages of Bonded Magnets
*Produced with high efficiency, stability and repeatability.
*Magnet and other part may form together in one step.
*Free choice of magnetizing direction-especially for multi-polar applications
*High dimensional accuracy-large quantity applications with minimum post-press machining.
*Thin-wall ring and complex shape magnets.
*High resistance to corrosion.
