Stamping Die Classification

Stamping die is a special process equipment for processing materials into parts or semi-finished products in cold stamping processing, called cold stamping die.

 

The mold consists of two parts, an upper mold and a lower mold. According to the mold structure analysis, the mold is roughly divided into a single-process die, a compound die and a progressive die.

 

Single-process die

In one stroke of the press, only one die of the stamping process is completed.

The single-step die has lower punching accuracy and productivity, but it is easy to automate production. The mold is made with a relatively low difficulty and the production cycle is short, so the mold cost is relatively low.

 

Compound die

There is only one station, in the one stroke of the press, two or more stamping processes are simultaneously completed at the same station.

The punching precision and productivity of the composite die are relatively high, but it is difficult to achieve production automation. The compound mold has a complicated structure and requires high precision, so the mold manufacturing and assembly are difficult and the cost is relatively high.

 

Progressive die

In the feeding direction of the blank, there are two or more stations, and in one stroke of the press, two or more stamping processes are successively completed at different stations.

Progressive stamping can complete multiple stamping operations in one press, suitable for automated operations and automated operations that adapt to high-speed punching. Progressive die are suitable for mass production of small and medium-sized parts. The mold structure is complex, and the manufacturing process is more difficult than the composite mold. Therefore, the cost of mold production is relatively high.
