Drawing process
Drawing is a process of cold forming a flat precut metal blank into a hollow vessel without excessive wrinkling, thinning, or fracturing. The various forms produced may be cylindrical or box shaped, with straight or tapered sides or a combination of straight, tapered, and curved sides. The parts may vary from 1/4" (6mm) diam parts or smaller to aircraft or automotive parts large enough to require mechanical handling equipment.

The deep drawing process is simply defined as the stretching of sheet metal stock, commonly referred to as a blank, around a plug. The edges of the metal blank are restrained by rings and the plug is deep drawn into a top die cavity to achieve the end shape that is desired.
There are many shapes that can be made through deep drawing and stamping including --
1. cups
2. cans
3. pans
4. cylinders
5. domes
6. hemispheres
7. tubes
8. hoppers
9. Irregular shaped products.
