ABSTRACT:
A magnet molding tool for controlling the orientation of magnetic particles in a polymer bonded magnet during injection molding. The tool has magnet mold having a mold cavity. A flux generator is connected to the magnet mold. The flux generator applies a magnetic field in the cavity. A non-magnetic cap is attached to the magnet mold and is dimensioned to modify the magnetic field in the cavity such that the orientation of the magnetic particles in the cavity varies proportionally to the dimensions of the non-magnetic cap. In an alternative embodiment, a slot is formed in the magnet mold and dimensioned to modify the magnetic field in the cavity.
