Description
Product Description:
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.
After the hot forging process ends, parts must be cooled rapidly to "set" the metal in its new shape. Care must be taken in the cooling process, however, as cooling hot forged parts too quickly can result in warping. Additionally, the hot forging process produces little to no material scrap, making it one of the most efficient fabrication methods available.

Hot Forging Characteristics Hot forgings can be divided into forgings with and without flash. Flash is necessary to produce complex 3D geometries with very different local cross-sections and secondary design elements. The flash acts as a brake on the material flow and slows the flow of excess material. Thus, high internal pressure is built up in the die, which forces the remaining material into the die cavities.
Flashless forgings are generally limited to axisymmetric components or components with cyclic-symmetric geometries.
Hot die forgings are usually manufactured in multiple steps. Semi-finished rolled products (round or rectangular sections) are used as blanks. In rare cases, continuous-cast material or profiled semi-finished products can be used.Hot Forging Materials Hot forging can be used to fabricate a broad spectrum of parts, and can be performed with most metal materials, including:

Hot Forging Advantages & DisadvantagesHot forging of metals as a fabrication technique has been around for centuries. Through the process mechanical properties of the metal that is being forged are improved through the metal's grain structure, which makes it tougher and stronger. Hot forging can be utilized with almost any metal and can be used to fabricate a wide range of parts. There are numerous advantages that hot forging can provide over cold heading. Some of the more common advantages and disadvantages of hot forging, include:
Advantages
Good ductility
Excellent surface quality
Increased flexibility
Good for custom parts
Disadvantages
Tolerances are less dimensionally precise
Cooling process must be carefully monitored
Warpage possibilities
