Forging Process

Forging

Forging Process is a metal forming process in which the forces are applied on the material such that the stresses induced in the material are greater than the yield stress and less than the ultimate stress so that the plastic deformation produced in the material will be used for changing the shape of the component is called as Metal Forming Process.

Advantages of Metal Forming Process:

Wastage Of material will be minimum or sometimes zero.

The grain orientation is possible.

In some material forming processes, an increase in strength and hardness of the material will be taking place.

The production rate is high.



When choosing a type of forging, buyers have a long list of options for producing a critical metal component. It can be challenging to make the right choice, because each technique comes with varying pros and cons, revolving around costs and logistics.

However, choosing the forging method brings a plethora of unique benefits unavailable with any other choice.

With regards to price and overall quality, metal forging brings the most value. This notion rings doubly when maximum part strength, custom sizes, and critical performance specifications are needed for the application.

Here are some of the more common methods used:

  • Closed die forging
  • Open die forging
  • Cold forging
  • Extrusion
  • Roll forging

How Does Forging Strengthen Metal?

Compared to other manufacturing methods, metal forging is known to produce some of the strongest manufactured parts available.  As the metal is heated and pressed, minor cracks are sealed and empty spaces found in the metal are closed up.

In addition, the hot forging process breaks up any impurities in the metal and redistributes such material across the metalwork. This results in vastly reduced inclusions in the forged part. Inclusions are compound materials embedded inside steel throughout manufacturing, causing stress points in the product.

Even though impurities should be managed during the initial casting process, this process will further refine the metal.

Another way that forging strengthens metal is through the altering of its grain structure. This has to do with the material’s grain flow as it deforms. Like other forming processes, a favorable grain structure can be created, making the forged metal sturdier.

Applications of Forging Process:

The applications of Forging Process are as follows.

  • Agriculture
    tools, Cutting tools, nails, machine parts spring, hook, screw, pin,
    etc.
  • Furniture
    manufacturing.
  • Aircraft
    and missile product.
  • Building
    materials like a handle, bolt, hinge, etc.
  • Home
    appliance and military products.

What Products Require Forged Metal?

The forging process is incredibly versatile and can be applied to anything from small parts measured in inches to components that weigh up to 700,000 lbs.

Forged products can be structural components in the following:

  • Critical aircraft parts:
  • Landing gear
  • Shafts for jet engines
  • Turbines
  • Transportation equipment:
  • Automobiles
  • Railroads
  • Crankshafts
  • Levers
  • Gears
  • Connecting rods

Also, forging is used to fortify hand tools (e.g., chisels, rivets, screws, and bolts).
