Stamping of sheet metal is a process based on permanent deformation by cold forming to produce a variety of complex three-dimensional shapes. A wide variety of associated operations are included and these are: Metal blanking, Sheet metal deep-drawing, Sheet metal bending, Sheet metal punching, Metal threading, Sheet metal laser cutting, etc.

Under CNC Machining, machine tools function through numerical control. The process is more precise, can produce many complex three-dimensional shapes that would be almost impossible to achieve with manual machining.

The process is often described as the shortest distance between raw material and finished product, which is a manufacturing process for producing accurately dimensioned, sharply defined, smooth or textured-surface metal parts. It is accomplished by forcing molten metal under high pressure into reusable metal dies or other metal products.
