Metal stamping is the process of forming a shape from a metal tube, sheet or coil using a press tool. The manipulation method is used to shape a die to produce accurate components.

What is Metal Forming?

It is a process of fashioning metal objects and parts through mechanical deformation. The process behind this is the workpiece looks reshaped but without removing the material and the mass, therefore, remains the same.

How Forming is Characterised?

Based on the industrial scale,

  • The production runs with many parts to maximise the production economy and indemnify the machine tools expenses
  • Large, expensive machinery is employed to accommodate high loads and stresses
  • High loads and stresses required between 50 N / mm2 and 2500 N / mm2

Process of Forming

Forming processes are categorised using the difference in stresses. Categories simplified, highly since the stresses operating at a local level in any process are complex and might involve a lot of stresses operating frequently.

Comprehensive Forming

It involves the processes where the primary means of plastic deformation is uni compressive loading.

  • Rolling
  • Extrusion
  • Die forming
  • Forging
  • Indenting


It is a continuous process for forming sheet, strip into long shapes of the essentially uniform cross-section. The material is fed through multiple pairs of contoured forming rolls, which shape the metal until it produces the desired cross-section.

Generally, rolling is a high-volume production process, but suits for shorter production too. This can be found in wide applications such as,

  • Construction
  • Aircraft
  • Automotive
  • HVAC industries and more

What are the Most Common Materials Used in this Process?

Mainly it consists of aluminium and mild steel.

Other materials used in this process are – coated, polished, plated materials.


It is a process where a workpiece of a length and cross-section is forced to flow through a die of the smaller sectional area, thus forming the work to a new cross-section.

You can see the cross-section will be uniform over the entire length of the metal extrusion.

Die Forming

The workpiece is usually a metal sheet, it is permanently reshaped around a die through plastic deformation by the processes of forming and drawing.

Simulations are carried out to avoid tears, too much thinning, cracks, etc. It is useful to estimate and overcome springback phenomenon. Once the forming process gets over and the tools are removed, the workpiece attempts to partially recover the first shape via elastic stresses.


It is a process of manufacturing that involves a shape of metal using localised forces. You see the blow uses via the use of a hammer or a die. According to the temperature, forging is classified into warm and cold forging.


Finally, the indenting process is a method of marking where you can see the information is permanently indented into the material. This is achieved by,

  • Character stamps
  • Dot peen pin

The message is made by applying a large force to the material being marked to form permanently.
