Progressive stamping is a high-efficiency metalworking process that integrates punching, coining, bending, and other forming techniques, combined with an automatic feeding system. A strip of metal, unwound from a coil, is precisely fed through multiple stations of a progressive stamping die. Each station performs one or more sequential operations, culminating in the creation of a finished part. The final station typically carries out a cutoff operation that separates the completed part from the carrier strip. The remaining web and previously punched scrap are treated as waste and, in high-volume production environments, are often transported to scrap bins via underground conveyor systems.
The progressive die is mounted in a reciprocating stamping press. As the press moves upward, the upper die lifts, allowing the strip to advance to the next station. When the press descends, the die closes and performs the designated forming operation. With every stroke, a fully formed part is ejected from the die.
To ensure accurate processing, the strip must be precisely indexed between stations—typically within a few thousandths of an inch. This is achieved using conical or bullet-shaped pilots, which insert into pre-pierced alignment holes on the strip. These pilots ensure accurate positioning, compensating for any limitations in the feed system's precision.
While progressive stamping can also be performed on transfer presses, these systems differ by using mechanical fingers to move parts between stations. For parts requiring complex, multi-step forming within the die, progressive stamping offers distinct advantages, most notably high-speed production, often exceeding 800 parts per minute.
However, progressive stamping does have limitations. It is not ideal for deep drawing operations, where the draw depth exceeds the part's diameter. Such tasks are better suited to transfer presses, which operate at lower speeds and allow components to remain securely held throughout the forming cycle. Progressive presses, by contrast, guide parts only during part of the cycle, typically with spring-loaded sleeves, which can introduce issues such as imprecise concentricity, ovality, or non-uniform wall thickness.
Higher raw material consumption due to continuous carrier strips
Increased tooling costs, as progressive dies are built in large, complex blocks with limited station-level adjustability
Inability to perform certain operations requiring part removal from the strip mid-process, such as beading, necking, flange curling, thread rolling, or rotary stamping
Progressive dies are typically made of tool steel, which offers superior durability, maintains a sharp cutting edge, and resists wear under high-impact, high-speed production.
Tooling cost is primarily influenced by the number and complexity of part features. It is generally recommended to keep part geometry as simple as possible to minimize tooling complexity and cost. Features located too closely together may not provide adequate clearance for the punch and could require additional stations. Similarly, narrow cuts or fine protrusions can complicate tool design and impact process reliability.
