PROBLEM TO BE SOLVED: To provide a method of forming articles of tooth profiles and its equipment with which articles of tooth profiles with chamfers are easily formed in a simple construction accurately and easily. SOLUTION: A forming equipment is provided with a mold 1 for forming chamfers that has multiple parts 11 for forming chamfers that form a chamfer C to meet tooth profiles on a surface of an edge of an axis line connecting S to S used when a body W is worked under plastic machining and with a mold for forming tooth profiles that form tooth profiles on a peripheral surface while corresponding with the chamfer C. Each part 11 for forming chamfers located on a mold 1 for forming chamfers has a controlling part 11a for flowing in the direction of the diameter that controls a flow J of materials into the outside of the direction of the diameter of a part 11 for forming chamfers and also has a part 11b for forming pre-fixing tooth profiles that forms pre- fixing tooth profiles Ta, which have narrower facewidth than those of desired tooth profiles of articles of tooth profiles, while corresponding to the chamfer C.
