Aluminum sheet Stamping is a kind of process that obtaining the required shape and size of the parts by outside force on the metal sheet, strip, pipe shape material use mould and press machine, in order to produce plastic deformation or separation. Stamping and forging belong to plastic processing (or pressure processing), called the forging press. The mainly stamping billets are hot rolling and cold rolling steel plate and steel belt.  

Stamping processing is a production technology that use of conventional or special equipment of the power, make the deformation sheet metal deformation in the mould. Thereby produce a certain shape, size and performance parts. Sheet metal, stamping mould and equipment are the three elements of stamping.
