The flat sheet of metal with the layout on it is fabricated through a number of different operations.
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.
It is one of the fundamental forms used in metalworking and can be cut.
The sheet metal specimen is clamped between two circular flat dies and a steel or round punch is pushed hydraulically into the sheet metal until a crack begins to appear on the stretched specimen.
Cutting folding bending edging making seams forming crimping and swaging.
