In sheet metal fabrication, Progressive stamping is the process of choice for fabricating high volumes of complex sheet metal parts quickly and cost effectively.
What is Progressive Stamping
Progressive stamping is used for parts that require more than a single bend or punch.
Prior to the use of progressive stamping equipment, manufacturing a part requiring more than a single process was inefficient, required more than one pass through a machine, and added manual labor to move the part or change a die.
Progressive stamping equipment accomplishes this within a single process. The machine includes multiple stations, each equipped with a tool to perform a specific process on the part.
A strip of sheet metal is fed into the progressive stamping machine and continues to move horizontally through the different presses.
The part typically remains attached to the metal strip until the last press when it is cut.
The process can be very fast and potentially produce hundreds of parts per minute depending on the specifications.
Progressive stamping equipment uses a combination of dies and stamping presses to perform different techniques like punching, blanking, embossing, coining, bending, hemming, stretching, and flanging – all to achieve the desired shape of a piece.
The process can use standard or custom dies.
Advantages for high volume production
Progressive stamping creates a high volume of parts in a very short time. The shape of the part can be complex and include combinations of holes, bends, folds or other shapes while still being manufactured efficiently.
The short cycle times, and the high-quality, very repeatable process is hard to achieve with any other process or series of processes.
