Disadvantages Of Sheet Metal Process

Shearing is less than ideal with harder metals.
Disadvantages of sheet metal process. For example using the process for cutting tungsten is simply a bad idea. It produces good surface finish. Stretch forming can be used to produce large parts with shallow contours but it is only suitable. Notable disadvantages of shearing.
This process is also used for straightening parts. However the disadvantages are that forming times are long production rates are low and the parts are not suitable for high temperature use. In some applications especially in stretch wrapping the process is slower than competitive processes and it is not suited to high volume production. Metal is more cost efficient when it comes to long term high volume lines of production.
Despite the pros the metal shearing process also has some notable disadvantages. Metal can go through a wider range of processes including chipping deep drawing casting forging welding and soldering. However stretch draw forming with mating dies can be done as rapidly and automatically as conventional.
