In industrial production, metal molds are parts or products that use various presses and special tools installed on the presses to make metal materials into required shapes. This special tool is collectively called metal mold. All kinds of tools and products used in our daily production and life are closely related to the mold, ranging from the base of the machine tool, the shell of the metal mold and the shell of the metal mold to the shell of an embryonic head screw, buttons and various household appliances. The shape of the mold determines the appearance of these products, and the processing quality and precision of the mold also determine the quality of these products. Due to the different materials, appearances, specifications and uses of various products, molds can be divided into non-plastic molds such as casting molds, forging molds, die-casting molds, stamping molds and plastic molds. Separate materials along closed or open contours. Such as blanking die, punching die, cutting die, cutting die, trimming die, cutting die, etc. Bending die is to bend the blank of sheet metal or other blanks along a straight line (bending line), so as to obtain a die with a certain angle and shape. Drawing die is a die that makes a blank plate into an open hollow part or further changes the shape and size of the hollow part. The forming die is a die that directly copies the blank or semi-finished workpiece according to the shape of the convex-concave die, and the material itself only produces local plastic deformation.

Such as expanding die, necking die, flaring die, wavy forming die, flanging die, shaping die, etc. Folding process combination single-process stamping die A die that only completes one stamping process in one stroke of a printing machine. Progressive die (also called continuous die) has two or more stations in the feeding direction of the blank, and two or more stamping processes are continuously completed at different stations in one stroke of the press. Progressive die (progressive die) is a cold stamping die that uses strip-shaped raw materials in one stamping stroke and completes multiple stamping processes at several different stations on a pair of dies at the same time. Every time the die is punched, the material belt moves at a fixed distance until the product is finished. In the process of continuous die stamping, the material belt always moves in one direction; Progressive die means that the material belt in the die moves in two or more directions after cutting. Call the automatic continuous die when the material belt enters the die; In the stamping production chain, the manipulator or other automation facilities used for stamping dies with different processes are used to move dies or parts to complete the stamping of workpieces. Rated dies are called multi-station dies.
