Stamping is also known Pressing, it is the operation that place a metal sheet in a stamping machine, then the stamping die punches or forms it to the design. There are two types called Single Stage stamping and Progressive Stamping depends on how many operations from a single press.
The feeding system pushes a strip of metal (as it unrolls from a coil) through all of the stations of a progressive stamping die. Each station performs one or more operations until a finished part is made. The final station is a cutoff operation, which separates the finished part from the carrying web. The carrying web, along with metal that is punched away in previous operations, is treated as scrap metal. Both are cut away, knocked down (or out of the dies) and then ejected from the die set, and in mass production are often transferred to scrap bins via underground scrap material conveyor belts.


Cost-Saving: As the Progessive Stamping die produces out a finished part from each punch, the manufacturing cost is much lower than the stage stamping where several punches needed for a finished part.
High-Efficiency: With support of the feeding system, the stamping machine runs automatically, and a finished part just needs a single punch.
For some certain very small hardwares, progressive stamping is a good option when it is too small to place it on the machine by hand.
