Abstract: The present invention provides a mandrel tool and method for more efficiently and consistently forming various shapes of material. In one embodiment of the invention, a pair of pliers having mandrel jaws that are shaped with a uniform cross sectional area throughout a length of the mandrel jaw is used to replace the traditional tapered mandrel. Because the mandrel jaws have a uniform cross sectional area, the wire, for example, can be wrapped multiple times around the mandrel jaw when it is desired to produce multiples of the same shape. For added versatility, the pliers can have opposing mandrel jaws, with different size cross sectional area.

Abstract: There is provided a method of manufacturing a metal shell formed body by cold forging for a metal shell of a spark plug. In the manufacturing method, a semi-finished formed body is first provided with a second inner step without the formation of an annular front end portion. After the semi-finished formed body is inserted from its front end side into a die, a punch is pushed into the semi-finished formed body from its rear end side. By pushing the punch, an annular front-facing surface of the punch is pushed onto the second inner step so as to press a front end portion of the formed body against an annular front end portion forming part of the die. By such a forming step, the metal shell formed body is obtained in which the annular front end portion is formed by extrusion.
