..., then the act of bending can create that shape (e.g., a car window frame or residential conservatory section). Sheet metal can be formed into a cylindrical shape by cup drawing , which is often the first step in the formation of a food or beverage can. In the aluminum industry, the semi-fabricated products...

... operations are integrated into a single three-part tooling. A cylindrical bending punch, attached to the bottom die, can be moved vertically by the top die, using a pressure cylinder. Thus, the U-profile is formed first. At its final lower position, the cylindrical punch acts as blank holder for the preform...
