Forging is an age-old process, tracing its roots back to the time of blacksmiths who shaped metal through the use of heat and pressure. In contemporary times, forging has become a critical manufacturing method for producing high-strength, complex-shaped components for various industries including automotive, aerospace, and machinery. This article provides an overview of the 5 fundamental steps for the correct forging manufacturing process.

Material Selection:

Before initiating the forging process, it’s crucial to choose the right material based on the desired end product. Materials typically used for forging include steel, aluminum, titanium, and certain alloys. The choice of material is governed by factors such as strength requirements, desired properties (e.g., corrosion resistance), and cost considerations.

Design & Mold Creation:

Forging requires a pre-designed mold or die to shape the heated metal. The design phase involves detailed blueprinting of the final product, considering specifications, tolerances, and structural requirements. Once the design is finalized, molds or dies are created. These molds can be of various types, including open-die, impression-die, or closed-die, depending on the required shape and intricacy.


The raw material, typically in the form of billets or ingots, is heated to a specific temperature that makes it malleable without melting it. The optimal temperature varies based on the chosen material. For example, carbon steel is usually forged at temperatures between 1,100°C and 1,300°C. Heating should be done uniformly to avoid internal stresses or structural inconsistencies.


Shaping the Metal: Depending on whether you’re using open die or closed die forging, employ a series of hammering or pressing actions to shape the metal into the desired form.

Reheat as Necessary: If the metal becomes too cool during forging, it may need to be reheated to maintain its malleability.

Trimming & Finishing:

Remove Excess Metal: Especially in closed die forging, there can be flash or excess metal around the forged part. This is typically removed using trimming dies.

Surface Finish: After trimming, the part may undergo various finishing processes like grinding, polishing, or shot blasting to achieve the desired surface finish and precision.
