Metal stamping is the process of transforming flat sheet metal into a net shape or near-net shape part. Sheet metal, in either blank or coil form, is placed into a stamping press, with specially-designed tooling and/or dies that blank, bend, punch, draw, flange, emboss, or otherwise alter the material into the desired shape.
In a single-stage metal stamping process, each stroke of the press produces a part; in a multi-stage metal stamping process, the material moves through a series of stamping stations, each of which performs a different forming process and takes the material one step closer to its final form. Progressive stamping uses one tool that performs multiple operations on one hit to make a complete part.
The metal stamping process may involve one or more of the following actions:
