However the disadvantages are that forming times are long production rates are low and the parts are not suitable for high temperature use.
Disadvantages of sheet metal process.
It produces good surface finish.
For example using the process for cutting tungsten is simply a bad idea.
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.
In some applications especially in stretch wrapping the process is slower than competitive processes and it is not suited to high volume production.
This process is for long parts with constant complex cross sections.
Parts have lower ductility and strength than those produced by forging.
Sheet metal forming basics.
Stretch forming can be used to produce large parts with shallow contours but it is only suitable.
Uniformly high density products are difficult to produce.
Peen forming is suitable for shallow contours on large sheets.
Metal is more cost efficient when it comes to long term high volume lines of production.
Shearing is less than ideal with harder metals.
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.
This process is also used for straightening parts.
Notable disadvantages of shearing.
Sheet metal forming process advantages and disadvantages 1.
Large or complex shaped parts are difficult to produce by pm process.
However stretch draw forming with mating dies can be done as rapidly and automatically as conventional.
In this type of forging operation a metal is elongated and as a result its cross sectional area decreases.
Despite the pros the metal shearing process also has some notable disadvantages.
