A microwave circulator is die cast as a unitary casing by the apparatus of this invention. The circulator is characterized by two-fold symmetry regarding the external dimensions of the device and three-fold symmetry regarding the internal dimensions of the device in the central coupling area. The casing defining the circulator is poured in a single operation with the use of three independently employed cores which define the three ports of the circulator.
