molds, various molds and tools used in industrial production to obtain the required products by methods such as injection molding, blow molding, extrusion, die-casting or forging molding, smelting, and stamping. in short, a mold is a tool used to shape objects. this tool is composed of various parts, and different molds are composed of different parts. it mainly realizes the processing of the shape of the article by changing the physical state of the formed material. known as the "mother of industry".

the definition and classification of the metal mold industry are introduced as follows. the shape of the mold determines the appearance of these products, and the processing quality and precision of the mold also determines the quality of these products. because of the different materials, appearance, specifications and uses of various products, molds are divided into non-plastic molds such as casting molds, forging molds, die-casting molds, and stamping molds, as well as plastic molds.

it is a mold for making the blank of a sheet into an open hollow part, or to further change the shape and size of the hollow part.

(4) forming die
it is a mold that directly replicates the blank or semi-finished workpiece according to the shape of the convex and concave molds, and the material itself only produces local plastic deformation. such as bulging die, necking die, flaring die, undulating forming die, flanging die, shaping die, etc.

process combination

(1) single-process mold in one stroke of the press, only one stamping process mold is completed.

(2) the composite mold has only one station, and in one stroke of the press, two or more stamping processes can be completed at the same time on the same station.

(3) progressive die (also called continuous die) in the feeding direction of the blank, there are two or more stations. in one stroke of the press, two or two passes are completed successively at different stations. die for more than one stamping process.
