NdFeB Bonded Magnet
NdFeB Bonded Magnet is manufactured by binding rapid quenching NdFeB powders. The rapid quenching NdfeB powders is mixed with plastic resin to form a magnet by compression molding with epoxy and infection 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.
