Neodymium Injection Bonded NdFeB Magnet With Black Resin

 

 

Brief Introduction

 

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 

 

 

Advantage

 

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