Sheet metal forming processes like blanking, bending, and deep drawing are used to manufacture automotive and other stamped metal parts. Progressive dies can produce parts quickly by performing multiple stamping operations simultaneously as the sheet metal passes through the die stations. Transfer lines also enable high-volume production by transferring pre-formed sheet metal components between successive presses using transfer dies.
