Progressive stamping is a metalworking method that can encompass punching, coining, bending and several other ways of modifying metal raw material, combined with an automatic feeding system.
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 per the requirements on the blueprint. 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.
The wasted web is either automatically cut in to smaller pieces or rolled on a coil. length can variate from tens to hundreds of meters, and the width of strip varies from less then a centimeter to one meter.
