Abstract

PURPOSE: To produce a resin mold coil wherefrom a duct member can easily be pulled out, by enabling the duct member to perform such a function as absorbs and lightens a clamping force of a coil conductor or a pressure produced resulting from a contraction occurring due to the hardening of a mold resin.
CONSTITUTION: A cylindrical plastic resin film being excellent in a mold-releasing property is formed in the shape of a desired duct member 6 by means of a jig 7 shaped in an arc of a circle. Afterwards, thermoplastic resins 8 are filled into the inside of the plastic resin film 5 to be hardened thereat. The hardened duct members 6 are located at equal intervals on a coil 11 formed in such a manner as winds a given number of coils around a bobbin 10, a coil 21 being further wound around the duct member 6 so arranged. A mold-releasing agent is applied on a surface of the duct member 6. The coil thus formed is set in a mold wherein a mold resin 9 is filled, the work being hardened by heating to be formed as a mold coil. The duct member 6 is then pulled from the work while the mold resin 9 goes through the process of hardening, whereby the mold coil wherein a cooling duct is formed is produced.
