Modern stamping design and development techniques permit the product designer to work with manufacturing and tooling engineers to design parts that can be manufactured with certainty. A Complex Stamping Figure 1. A complex stamping is produced by a variety of forming operations, each of which may be analyzed separately.

Uncertainty concerning the Manufacturability of complex stampings often results in added expense and delay factors such as: 1. Trial production on temporary tooling to prove process feasibility. 2. Delays in marketing the product containing the stamping while the process or product design is changed.
