Shearing is less than ideal with harder metals.
Disadvantages of sheet metal process.
Peen forming is suitable for shallow contours on large sheets.
This process is for long parts with constant complex cross sections.
However stretch draw forming with mating dies can be done as rapidly and automatically as conventional.
Notable disadvantages of shearing.
For example using the process for cutting tungsten is simply a bad idea.
Metal is more cost efficient when it comes to long term high volume lines of production.
It produces good surface finish.
In some applications especially in stretch wrapping the process is slower than competitive processes and it is not suited to high volume production.
Despite the pros the metal shearing process also has some notable disadvantages.
Sheet metal forming process advantages and disadvantages 1.
Stretch forming can be used to produce large parts with shallow contours but it is only suitable.
