In short, a mold is a tool used to make a shaped article, the tool being made up of various parts, different molds being made up of different parts. The processing of the appearance of an article is realized mainly through the change of the physical state of a formed material. The element has the name of "industrial mother".

The blank is formed into a tool with a specific shape and size under the action of external force. The method is widely applied to blanking, die forging, cold heading, extrusion, powder metallurgy part pressing, pressure casting and the forming processing of compression molding or injection molding of products such as engineering plastics, rubber, ceramics and the like. The die has a specific contour or cavity shape, and the blank can be separated (blanked) according to the contour shape by applying the contour shape with the cutting edge. The blank can obtain a corresponding three-dimensional shape by using the shape of the inner cavity. The mold generally comprises a movable mold and a fixed mold (or a male mold and a female mold), which can be separated or combined. When the blank is closed, the blank is injected into the die cavity for forming.
