Forging Suppliers – Global Sourcing considerations

Forging suppliers involve in different metalworking processes. They bring a work-metal to the desired shape and size as per the customer need. This article will discuss the processes performed by forging suppliers to help you achieve best production results.

Forging suppliers – What operations do they perform?

In this process, forging suppliers apply compressive forces on the work metal. Thereby, the work metal deforms into the desired shape. Metal forming has several part production applications. It includes industries including automotive and aircraft. This method produces unique metal parts with customized size, shape, etc.

In this process, the metal temperature is the basis of its types.
Let us refer the re-crystallization temperature here as RcT.

In general, forging suppliers compare the metal temperature to its RcT This is how they estimate the type of process.

If the metal temperature is above its RcT, it comes under hot forging

Likewise, If the metal temperature is between its RcT and 30% of the RcT, it comes under warm forging.

If the metal temperature is below 30% of the RcT, it comes under cold forging.

Likewise, the strengthening of material through heat treatment is known as Tempering.

Drop forging:

This technique includes a giant hammer striking a workpiece. The hammer strikes the workpiece many times again and again to bring it to the shape of the. This process deforms only the surface of the metal. This process is of 2 types:

  • Open-die technique
  • Closed-die technique/ Impression-die technique

Open die forging:

During this process, the die does not completely enclose the workpiece. While hammered, the workpiece deforms into the shape of the die.  In addition, excessive metal let out of the die region. Further processing removes the residue metals.

The successive processes conducted after surface deformation are as follows:


Once a drop forging is complete, it is essential to bring the metal to its desired shape. To do so, forging suppliers perform deformation processes. The hammers strike along the entire length of a metal bar. Thereby, the metal extends in length reducing the cross-section. This process is known as Cogging.


The process in which concave dies deforms the work metal is known as Edging.


Like the Edging technique, in fullering, the convex dies deform the work-metal.

Closed die forging/ Impression-die forging:

This process brings out calculated or pre-designed impressions on the metal surface. The die used in this process looks like mold. The hammer can strike the metal surface repeatedly. This causes the metal to flow along the die cavities. It causes residue metal to come out of the die region. This residue formed after hammering is known as Flash.

Press Forging:

This process is like drop forging. In a forging press, a hammer strikes the metal surface. But, the strikes on the metal are slow when compared to the latter. In the latter method, only the surface of the metal undergoes deformation. Further processes like cogging and edging deform the complete metal (in and out). Whereas in this method, no secondary processes are involved. The complete metal reshapes to its required shape in this process without any application of secondary deformation techniques.

Upset Forging:

This technique uses high-speed machines. During this process, the metal’s length reduces. In addition, the diameter or cross-sectional region expands by compression.

Automatic Hot Forging:

This is a modernized technique where the deformation of metals is automated. The metal bars deform inside the machine by hot forging. On process completion, one can get the output in the form of forged metals.

Roll forging:

During the roll forging process, forging suppliers feed in the hot metal bars into rolls. These rolls are either cylindrical or semi-cylindrically grooved. The hot metal bars get the shape of the grooves. The forging suppliers repeat the process of inserting the metal bars into the rolls. They perform the operation until the bar reaches the desired shape. Like roll forging, rolling ring shapes of metals is known as Ring forging or Ring roll forging.

Several secondary operations continue after the first reshaping of metal to remove excess/ residue metal. This expands the cost of production on the other hand. This precision forging technique minimizes time and cost. These products are further quality-checked by destructive testing.

Induction forging:

Induction forging involves heating operations. The other techniques combine with this heating technique at the required stages to achieve desired metal shapes.

Multi-directional forging:

This process runs in different directions at the same time on a single workpiece. The direction of the ram changes during the process by wedges.

Isothermal technique:

This process heats the metal and the die at similar temperatures.Overall, we believe that these basics about the process will help you in Forging supplier sourcing.
