Design of sheet metal parts ppt.
Sheet metal fabrication in china sheet metal is a kind of integrated metal cold working technology for metal sheet usually in under 6mm usually the parts plastically deformed by handwork or stamping die to form your desired shape and size and it also can be further formed more complex parts by welding or other metal cold working technology including laser cutting punching bending.
Material and size selection.
Sheet metal is one of the most versatile materials and processes in the world today.
