bonded ndfeb magnet

Instruction :

Plastic-bonded Nd-Fe-B magnet is manufactured by bindin g rapid-quenching Nd-Fe-B powders.The rapid-quenching Nd-Fe-B powders is mixed with plastic resin to form a magnet by compression molding with epoxy and infection molding with nylon.The injection molding has a particularly useful feature in large-quantity. The injection molding's magnets values are lower than the compression molding because of their relative low density.The shapes of high dimensional accuracy can be produced without secondary processing.The magnet surfaces are treated by epoxy coating or Nickel-plating to prevent corrosion.
