Abstract
A die cast, two pole, insulated magnet assembly and method of manufacture. A magnetic body of preferably ceramic ferrite material is sandwiched between two pole pieces such that each pole has a free end which projects beyond the magnetic body. The sandwiched pieces are then inserted into a female mold having a main mold cavity and a pair of opposed pole cavities formed therein to receive the projecting ends of the poles, thereby correctly aligning them. A metal sleeve is then inserted into the main mold cavity such that an annular space is created between the sandwiched magnet assembly and the sleeve. Molten zinc is then poured into the mold and sleeve to encapsulate the magnet except for the projecting ends of the poles. After the zinc has solidified, the assembly is removed from the mold.
