Sheet metal often contains sharp edges with "burrs" after initial production. Hemming is a forming process that involves deburring sheet metal to produce smooth edges.
Another common sheet metal forming process is bending. Companies typically use brake presses or similar machine presses to bend sheet metal.
Sheet metal can also be ironed to achieve a uniform thickness. For example, most aluminum cans are made of ironed aluminum. In its raw state, the aluminum sheet is too thick for a beverage can, so iron it for a thinner, more uniform composition.
In recent years, laser cutting has become an increasingly common sheet metal forming process. With laser cutting, the metal sheet is exposed to a high-energy laser that burns holes in the metal.
A lesser known sheet metal forming process is hydroforming. Like deep drawing, hydroforming involves drawing a blank over a die. So, what is the difference between hydroforming and deep drawing? The main difference between the two processes is that deep drawing requires multiple reductions, whereas hydroforming can be done in a single step.
Finally, stamping is a sheet metal forming process that involves punching holes in sheet metal using punches and dies. Sheet metal is placed between the punch and die. Next, the punch is pressed down and through the metal plate to form a hole.
