What is the difference between punching die and blanking die in stamping die? The more specific and detailed, the better. If I am satisfied, I will get extra points! )
Sheet metal parts will be separated along the closed contour line. If the material in the contour line is used as a blanking part, this process is called blanking, and the die that completes the blanking process is called blanking die. If the material outside the contour line is used as a blanking part, this process is called stamping, and the die that completes the stamping process is called punching die. Both of them are blanking dies, and the two blanking principles are the same, but the manual definition is different.
