What is metal presswork?

Presswork forming is the process where a pressing force is applied to a material to deform it. This is to match the size and shape of the die.

Metal presswork is a method of fashioning metal objects and parts through mechanical deformation.

The reasoning behind this is so that the piece being worked on looks reshaped. But its mass and materials are unchanged.

How forming is characterised

Based on the industrial scale:

  • The production runs with many parts to maximise the production per usage since it is quite expensive to run.
  • 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 are very heavily simplified. This is because the stresses operating at a local level in any process, are complex and might involve a lot of stresses operating frequently.

Common materials used in the presswork process?

It mainly consists of aluminium and mild steel.

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

Comprehensive presswork forming

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

  • Rolling
  • Extrusion
  • Die forming
  • Forging
  • Indenting


It is a continuous process for forming metal tubes, using metal sheets. The material is fed through metal rollers, which shape the metal as it goes through.

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


Extrusion is the deformation of either metal or plastic forced under pressure through a die to create a shape

Die Forming

The die is a specialised tool used in manufacturing industries. It is a block that is used for pressing and forming materials like sheet metal and plastic.

For the framing of sheet metal, for example, car body parts, two sections might be utilised. One, called the punch, which plays out the extending, twisting, and blanking activity. While another part is known as the bite the dust square safely cinches the workpiece and gives comparative extending, bowing, as well as blanking task.


It is a process that involves a shape of metal using localised forces. Traditionally a hammer would be used but now we also use die. There are two types of forging: warm and cold forging. Can be done using heat or very high levels of pressure.


Lastly, the indenting process is a method of marking the piece. This is similar to engraving objects. This is achieved by:

  • Character stamps
  • Dot peen pin

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