Stamping die is a kind of processing method using impact pressure for die processing, but in fact, there are several obviously different processes in stamping die. Many people will wonder what kinds of stamping dies are there and what are the differences? Today, Xiaobian will take you to have a look.

Engineering die: also known as "single process Die", it refers to a die 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 by manipulator, and then put into the mold at the next station to continue production. The whole product is not completed until one process of the mold is completed. This kind of mold is simple to maintain, but it is time-consuming and laborious to produce, requires more labor and time cost, and the product scrap rate is high

Stamping die

Composite die: common composite die structures include composite blanking, composite drawing, etc. this die structure is slightly different from other engineering die structures. The punch (also known as male die or punch) is designed in the lower die. The other templates are the lower splint (fixed punch), the lower stop baffle and the lower stripper plate (outer stripper). The upper die is composed of the mother die (or knife edge), the inner stripper plate and the upper backing plate. The inner stripper is hung on the upper backing plate with an equal height sleeve, and then pressed with a driving rod or spring. For example, for the composite die used for blanking, the internal stripping is generally 0.50mm from the mother die, which can not be lower than the mother die, otherwise the knife edge of the mother die is easy to collapse or do not strip.

Continuous die: also known as "progressive die", it refers to a die that completes two or more stamping processes at different stations at the same time in one stroke of stamping. This kind of die is difficult to maintain and needs experienced fitter to operate, but the production efficiency is very high. If it is played fast, it can produce thousands of products in an hour, Save labor and time costs.
