PROBLEM TO BE SOLVED: To provide a method of molding a meandering annular coil and a molding apparatus thereof, capable of manufacturing a meandering coil having high out-of-roundness and satisfying the product dimension accuracy as a target with high yield. SOLUTION: In step S1, the basic press-in quantity of each molding die corresponding to product dimension is set. In step S2, an excessive press-in quantity for correcting total deviation is added to the basic press-in quantity of each molding die to make a first individually corrected press-in quantity. In step S3, a meandering annular coil is molded from an annular winding coil at the first individually corrected press-in quantity. In step S4, the individual deviation between an actual finished dimension and a product dimension is measured, in step S5, it is checked whether the individual deviation is within a range of the product dimension accuracy, and in step S6, a second individual corrected press-in quantity in which the individual deviation as the excessive press-in quantity is added to the first individual corrected press-in quantity is obtained. The steps S3-S6 are repeated until the individual deviation is within the range of product dimension accuracy. COPYRIGHT: (C)2010,JPO&INPIT
