Progressive die stamping uses a sequence of stamping stations. A metal coil is fed into a reciprocating stamping press with progressive stamping dies. The die moves with the press, and when the press moves down the die closes to stamp the metal and form the part. When the press moves up, the metal moves horizontally along to the next station. These movements must be precisely aligned as the part is still connected to the metal strip. The final station separates the newly-fabricated part from the rest of the metal. Progressive die stamping is ideal for long runs, because the dies last a long time without becoming damaged, and the process is highly repeatable. Each step in the process performs a different cut, bend, or punching operation on the metal, thus gradually achieving the desired end-product shape and design. It is also a faster process with a limited amount of wasted scrap.

Stamping Advantages
Faster and cost-effective production for large volume production
Accuracy and precision for complex shapes and producing identical pieces
Once the die is created, can produce large volumes quickly
Well suited for small parts requiring micro-precision
Versatile sheet metal fabrication process that can include punching, blanking, embossing, flanging, bending, or coining
Scrap leftovers can be recycled

Progressive die stamping is suitable for producing large volumes of parts with strict tolerance specifications. This stamping method involves feeding a coil of metal through the stamping press that simultaneously punches, bends, and shapes the parts.
The workpiece remains attached to the base strip from beginning to end—separating the individual finished parts from the base metal strip is the final step in the operation.
The main advantages of progressive die stamping include:
— Quick production of many small parts with tight tolerances
— Low setup time
— Reduced labor costs
— Long run lengths
— Minimal scrap
— Combining multiple operations saves time/money
In short, progressive die stamping can make parts with complex geometries quickly, economically, and with high rates of repeatability. However, progressive die stamping does require investing in permanent steel tooling. It is also not suitable for parts requiring deep drawing.
Progressive die stamping may use a variety of metals as the base material. Steel, aluminum, copper, stainless steel, and brass are all commonly used. A range of noble metals, titanium, and the superalloy Inconel are also used. Even non-metallic components can be fabricated with progressive die stamping in some instances.
