It produces good surface finish.

Disadvantages of sheet metal process.

Notable disadvantages of shearing. Sheet metal working process 2 17 2016 compiled edited by sivaraman velmurugan 33 disadvantages of hot working lower dimensional accuracy higher total energy required which is the sum of the thermal energy needed to heat the workpiece energy to deform the metal work surface oxidation scale thus poorer surface finish shorter tool life dies and rolls in bulk deformation. Peen forming is suitable for shallow contours on large sheets. Despite the pros the metal shearing process also has some notable disadvantages.

Large or complex shaped parts are difficult to produce by pm process. Stretch forming can be used to produce large parts with shallow contours but it is only suitable. 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 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. However the disadvantages are that forming times are long production rates are low and the parts are not suitable for high temperature use. Metal is more cost efficient when it comes to long term high volume lines of production.

In this type of forging operation a metal is elongated and as a result its cross sectional area decreases. Parts have lower ductility and strength than those produced by forging. Upsetting in upsetting cross sectional area of the workpiece is increased and as a result length of workpiece decreased. For example using the process for cutting tungsten is simply a bad idea.

Some powders such as aluminum magnesium titanium and zirconium in a finally divided state present fire hazard and risk of explosion. Uniformly high density products are difficult to produce. With the use of the industrial manufacturing process sheet metal is formed by working metal into flat and thin pieces sheet metal is one of the very convenient ways that is used in metal working and it can be mended and cut into various shapes and dimensions.
