Whether it’s a precision aerospace component or a heavy-duty automotive crankshaft, forging ensures the performance and reliability that critical industries demand.

 

 

 

5 Key Steps in the Forging Process

 

1. Heating

 

The forging process begins with heating the raw metal—often billets or ingots—to a specific temperature, usually between 1,000–2,200°F (depending on the material). The goal is to soften the metal enough to allow it to deform without cracking.

 

There are three types of forging based on temperature:

• Cold Forging (room temperature)
• Warm Forging (intermediate temperature)
• Hot Forging (high temperature)

Each method affects the metal’s final properties and is selected based on the application.

 

 

2. Forming

 

In this stage, the heated metal is positioned into a die or mold, and shaped using mechanical force. Forming can involve simple or complex dies depending on the part geometry.

This is the step where the metal begins to take its rough form, preparing it for more precise shaping. For high-volume manufacturing, automated forging systems are often used for speed and consistency.

 

 

3. Forging (Deformation)

 

Now comes the critical step: actual forging. Using powerful hammering or pressing, the metal is compressed and reshaped into its final geometry. This force not only molds the shape but also refines the metal’s grain structure, enhancing its mechanical properties.

 

Types of forging include:

• Open-Die Forging – ideal for large, simple shapes.
• Closed-Die (Impression-Die) Forging – for complex, high-precision parts.
• Upset Forging – increases the diameter of a section.
• Roll Forging – continuous deformation using rollers.

 

 

4. Cooling

 

After forming, the forged metal must be cooled at a controlled rate. This cooling phase is critical to achieve the desired hardness, toughness, or ductility. Improper cooling can lead to internal stress, warping, or cracking.

 

In some cases, components are immediately heat-treated (tempered or quenched) after forging to further improve material performance.

 

 

5. Finishing

 

The final step involves removing any excess material (also called flash), surface treatment, and machining. Some forged parts require secondary processes like CNC machining to meet tight tolerances or to create holes, threads, or other features.

 

Finishing ensures that the forged product meets exact specifications and is ready for use in its intended application.
