From Flat Sheet to Finished Part

Features Close to a Bend Need Attention

A hole or slot positioned near a forming area may behave differently from the same feature located on a flat section.

Springback Is Part of Forming

After bending or forming pressure is released, sheet metal may recover slightly. The amount depends on material, thickness, bend geometry, and forming method.

For this reason, the tool and forming process may need adjustment so that the finished part matches the required geometry rather than simply reproducing the nominal tool angle.

Material Direction Can Influence Forming

Sheet material behavior is not always identical in every direction. For parts with several bends or formed areas, bend orientation and material condition may need to be considered during tooling review.

Not Every Feature Has to Be Created in One Stroke

A stamped component may be produced through several operations rather than one forming action. Piercing, bending, flanging, embossing, trimming, and restrike operations can be arranged in sequence according to the part geometry and production method.
