Metal is more cost efficient when it comes to long term high volume lines of production.
Disadvantages of sheet metal process.
This process is also used for straightening parts.
Shearing is less than ideal with harder metals.
In some applications especially in stretch wrapping the process is slower than competitive processes and it is not suited to high volume production.
Notable disadvantages of shearing.
It produces good surface finish.
However stretch draw forming with mating dies can be done as rapidly and automatically as conventional.
This process is for long parts with constant complex cross sections.
Sheet metal forming process advantages and disadvantages 1.
Despite the pros the metal shearing process also has some notable disadvantages.
Peen forming is suitable for shallow contours on large sheets.
Metal can go through a wider range of processes including chipping deep drawing casting forging welding and soldering.
