Progressive stamping is a highly efficient metalworking process that combines punching, coining, bending, and other metal forming operations with an automatic feeding system. This system continuously feeds a strip of metal—unwound from a coil—through a series of die stations, each performing a specific task until the final part is completed.

At the last station, a cutoff operation separates the finished part from the carrier strip. The remaining strip, along with any punched-out scrap from earlier stages, is considered waste. In mass production environments, this scrap is typically removed from the die area and collected in scrap bins via underground conveyor belts.

The die is mounted in a reciprocating stamping press. As the press moves upward, the upper die lifts, allowing the material to advance. When the press descends, the die closes and executes the stamping operation. With every press stroke, one finished part is produced and ejected.

Because each station adds more features to the part, precise material advancement is critical. To ensure alignment within just a few thousandths of an inch, bullet-shaped or conical pilots are inserted into pre-punched round holes in the strip. These pilots provide alignment accuracy beyond what the feeding mechanism alone can achieve.

Progressive stamping can also be performed on transfer presses, which move the part from station to station using mechanical "fingers." While transfer presses operate at slower speeds, they are more suitable for complex forming processes where the part must be held in position during the entire cycle—such as high-precision deep drawing, where the draw depth exceeds the part’s diameter.

Advantages of progressive presses include exceptional production speeds—often exceeding 800 parts per minute—making them ideal for high-volume manufacturing. However, they are not well-suited for operations requiring the part to leave the strip mid-process, such as beading, necking, flange curling, thread rolling, or rotary forming.

Limitations of progressive stamping compared to transfer stamping include:

• Greater raw material consumption

• More expensive tooling due to block-style dies with minimal per-station adjustability

• Limited capability for complex forming tasks that require part separation before the final stage

Tooling is typically made from tool steel, selected for its durability, sharpness retention, and ability to withstand the high shock and abrasive conditions of stamping.

The overall cost of a progressive stamping project is largely influenced by the number and complexity of part features. To minimize tooling costs, designers are encouraged to simplify part geometries where possible. Features that are tightly spaced may necessitate additional stations or pose clearance challenges for punching tools, especially when narrow cuts or fine protrusions are involved.
