Forging is a manufacturing process that involves offering shape to the metal through rolling, pressing and hammering. The compressive force is delivered using dies and hammers. Forging manufacturers categorize forging processes based on the temperature at which the forging process takes place, i.e. hot, warm or cold forging.
Forging manufacturers can forge a wide array of metals which include alloy steel, stainless steel, carbon steel, brass, aluminum, copper etc.
Forging parts manufacturer can manufacture parts accurate and high-quality mechanical properties while minimizing wastage. Forging manufacturers can mass produce parts and achieve required mechanical properties in their finished goods at economical costs.

Different Methods of Forging

  • Drop Forging

Drop forging involves dropping a heavy hammer on a metal towards molding it into shape and dimensions of the die. Dies can be referred to as the distinctively shaped mold that comes in contact with the metal during the forging process. There are mainly two forms of drop forging, i.e. Smith Forging, also known as open-die forging and Impression-die forging, referred as the close-die forging. Forging hammer manufacturers need to assess the forging needs and processes used before supplying plant and machinery to the Forging parts manufacturer.


  • Open-die forging

Smith Forging involves a hammer striking and deforming a metal against a stationary anvil. In Smith Forging, the metal is not entirely confined in the dies, and this allows it to flow with the exception in areas where the metal is in contact with the dies. Operators are responsible for positioning and orient the metal towards achieving its desired final shape. Smith Forging uses flat dies with specially shaped surfaces, depending upon the operation. Smith Forging is suitable for simple, large and customized metal parts, and components.Open-Die-Forging

  • Closed-die Forging

Impression-die forging, also known as Closed-die forging involves planking a die which is attracted to an anvil. A heavy hammer is repeatedly dropped on the metal, which causes the metal to flow into and fill the cavities of the die. The hammer is repeatedly struck on the metal at a fast pace, which causes the excess metal to be pushed out of the die cavities, which results in a flash. This flash tends to cool down faster than the rest of the metal, making than the rest of the metal. Flash has removed post forging.Close die forging

  • Roll Forging

Roll Forging involves using 2 horizontally cylindrical or semi-cylindrical roll which deforms a round or a flat bar stock. This process is used to reduce the thickness and increase the length of the metal.
This heated bar is then inserted and passed between two rolls which contain one or more distinctly shaped grooves, which progressively shapes the metal as it is rolled through the forging machine. The process is repeated continuously until the metal acquires a desired size and shape.Roll Forging


  • Press Forging

The process of Press forging utilizes a slow and constant force or pressure on the metal instead of impact, as in the case of drop-hammer forging. The material achieves a deeper deformation when the ram travels slower. This helps in attaining uniformity throughout the entire volume of the material. Unlike drop-hammer forging, Press Forging only deforms the exterior of the material while the interior stays intact. Forging parts manufacturer can control the compression rate and internal strain in press forging.

Press Forging
Forging press manufacturers need to assess the forging needs and processes used before supplying plant and machinery to the forging suppliers and manufacturers.
