Stretch forming can be used to produce large parts with shallow contours but it is only suitable.
Disadvantages of sheet metal process.
Shearing is less than ideal with harder metals.
Metal can go through a wider range of processes including chipping deep drawing casting forging welding and soldering.
This process is for long parts with constant complex cross sections.
Despite the pros the metal shearing process also has some notable disadvantages.
Notable disadvantages of shearing.
For example using the process for cutting tungsten is simply a bad idea.
However stretch draw forming with mating dies can be done as rapidly and automatically as conventional.
Peen forming is suitable for shallow contours on large sheets.
Sheet metal forming process advantages and disadvantages 1.
However the disadvantages are that forming times are long production rates are low and the parts are not suitable for high temperature use.
This process is also used for straightening parts.
