  • Stretching
  • Hydroforming
  • Lubrication

Bending and Flanging

Bending of sheet metal is a common and vital process in manufacturing industry. Sheet metal bending is the plastic deformation of the workpiece over an axis, creating a change in the part's geometry. Similar to other metal forming processes, bending changes the shape of the workpiece, while the volume of material will remain the same. In some cases bending may produce a small change in sheet thickness. For most operations, however, bending will produce essentially no change in the thickness of the sheet metal.

Hot Forming Fundamentals

Hot forming sheet metal components is becoming common and expected with today's Advanced High-Strength Steels (AHSS). AHSS is the fastest growing set of steel grades in automotive applications. AHSS offers enhanced formability at higher strength. Cold forming AHSS can lead to severe and unpredictable springback. Hot forming relieves residual stresses in the formed workpiece which solves the springback problem. The quenching operation leads to a martensitic microstructure possessing ultra-high strength.
