What Is Stamping?

By : Categories : Blog,Industry Comment: Comments Off on What Is Stamping?

stamping or pressing is a manufacturing process used to convert flat metal sheets into final shapes. In this process, a flat sheet of metal, either in the form of a blank or in the form of a coil, is placed in a stamping press where a tool and die surface forms the metal into a final shape.

Stamping encompasses a variety of sheet metal forming manufacturing processes, such as punching using a machine press or stamping press, blanking, embossing, bending, flanging, and coining.

This could be a one-step process where each stroke of the press creates the desired shape on the sheet metal part, or it could be done through a series of steps. The process is usually carried out on sheet metal, but can also be used on other materials such as polystyrene.

Progressive dies are commonly fed from a coil of steel, coil reel for an unwinding of the coil to a straightener to level the coil and then into a feeder which advances the material into the press and dies at a predetermined feed length. Depending on part complexity, the number of stations in the die can be determined.

Stamping is usually done on cold metal sheets. See Forging for hot metal forming operations.
