Sheet metal fabrication is the process of turning flat sheets of steel or aluminium into metal structures or products, by cutting, punching, folding and assembling. Sheet metal can be cut, bent or stretched into nearly any shape, which is generally done by cutting and burning the metal.

Sheet metal forming includes treatments such as bending, spinning, drawing, or stretching implemented by dies or punching tools. Forming is mostly performed on a press and parts are formed between two dies.

Plasma cutting – This process involves the use of a plasma cutter machine to cut through aluminum. The cutter utilizes hot jets of plasma to cut through aluminum at high speeds, which reduces the possibility of contamination. The plasma cutting process is highly efficient and quick.
