Stamping die is a special process equipment for processing materials (metal or non-metal) into parts (or semi-finished products) in cold stamping processing, called cold stamping die (commonly known as cold stamping die). Stamping is a pressure processing method that uses a mold installed on a press to apply pressure to the material at room temperature to cause separation or plastic deformation to obtain the required parts.

Composite mold: Common composite mold structures include composite blanking, composite stretching, etc. This mold structure is slightly different from other engineering mold structures. The punch (also called male mold or punch) is designed in the lower mold, and the other templates are the lower splint (fixed punch), the lower stop baffle and the lower stripper (outer ejection), and the upper mold in turn It is composed of a master mold (or knife edge), an inner stripping plate and an upper backing plate. The inner stripping is hung on the upper backing plate with a contour sleeve, and then it is pressed by a rod or a spring. For example, for the composite mold used for blanking, the inner part is generally 0.50mm out of the master mold, and it should not be lower than the master mold, otherwise the knife edge of the master mold is easy to collapse or does not come off.

Engineering mold: also known as “single process mold”, refers to a mold that can only complete one stamping process in one stroke of stamping. After the completion of this project, the product needs to be taken out of the mold manually or with a robot, and then placed in the mold at the next station to continue production. The entire product is not considered complete until one process of the mold is completed. This kind of mold is simple to repair, but it is time-consuming and labor-intensive to produce, and requires more labor and time costs, and the product scrap rate is high

Continuous die: also known as “progressive die”, refers to a die that completes two or more stamping processes at different stations at the same time during one stroke of stamping. This type of die maintenance is difficult It is large and requires an experienced fitter to operate it, but the production efficiency is very high. If the speed is fast, thousands of products can be produced in an hour, saving labor and time costs.
