Hot forging is a metalworking process in which metals are plastically deformed above their recrystallization temperature, 

which allows the material to retain its deformed shape as it cools. Hot forging is accomplished using hydraulic or pneumatic 

hammers, presses, and other similar machinery that are used to compress the heated metal into its desired part shape. This 

is most often achieved using a custom die. The dies used in hot forging are custom-made to match the customer's part 

designs. Because hot metal is more pliable, this process allows for more intricate shapes than cold forging, making a vast array 

of part geometries possible. However, tolerances used in hot forging are generally not as tight as in cold forging.

Hot forging begins with a forged metal ingot or a cast metal piece. The work stock is heated until it reaches its plastic deformation

temperature (recrystallization temperature), which must be maintained throughout the hot forging process. Depending on the 

material, this temperature can be as high as 1200°C. As the material is formed and shaped, its grain structure is broken down and 

homogenized into finer grains, which increases the yield strength, ductility, and toughness of the material.

Our range of products includes Forged Transmission Gears, Forged Pinions Gears, Forged Crown Wheels, Forged Ring Gears and 

Forged Internal Gears.Spur Gears, Helical Gears,Bevel Gears,Spiral Gears etc..
