"Forging" as described in the full text of this work is one of the metal pressure processing methods, which refers to a process for changing the shape of a metal material by pressure to obtain a workpiece having a certain mechanical property, a certain shape and size, depending on the processing time. The workpiece temperature can be divided into hot forging, warm forging and cold forging. For example, at a suitable temperature, the billet is hammered or pressurized by a conventional molding machine, so that the billet is plastically deformed one after another, and finally becomes certain. Shapes and dimensions of the workpiece, which may be referred to as forgings, are understood by those of ordinary skill in the art to which the present invention pertains.

The "pressing process" as referred to in the entire text of the present invention refers to a process in which a mold receives a pressure source from the beginning to the end of the pressure. For example, when a power element is used to apply pressure to the mold, the mold and the power element are in contact with each other to separate from each other.
