Disadvantages of sheet metal process.

Stretch forming can be used to produce large parts with shallow contours but it is only suitable. For example using the process for cutting tungsten is simply a bad idea. Despite the pros the metal shearing process also has some notable disadvantages. Shearing is less than ideal with harder metals.

This process is for long parts with constant complex cross sections. However the disadvantages are that forming times are long production rates are low and the parts are not suitable for high temperature use. 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.

This process is also used for straightening parts. Metal is more cost efficient when it comes to long term high volume lines of production. Peen forming is suitable for shallow contours on large sheets.
