Stamping is a general term that encompasses a broad range of metal forming capabilities and industrial uses.Parts produced by metal stamping can range from 0.25 inches in diameter or smaller, to very large aircraft, automotive and appliance parts.Sometimes referred to as metal pressing, it is classified as a cold forming or cold working process, meaning it is usually done at room temperature.
The stamping process is considered deep drawn stamping, or deep draw, when a part is pulled (drawn) into a die cavity and the depth of the recess equals or exceeds the minimum part width.Deep drawing uses radial tension-tangential compression to shape the metal.This process transforms flat sheet metal, or blank, into a hollow vessel that may be cylindrical or box-shaped, with straight or tapered sides or a combination of straight, tapered and curved sides.The vessel is then redrawn through a series of dies, reducing its diameter and increasing its length with minimal change to the wall thickness.
