Wikimedia Commons has media related to Forging. For industrial processes steel alloys are primarily forged in hot condition. The principle behind the machine is simple: raise the hammer and drop it or propel it into the workpiece, which rests on the anvil. Contour-formed metal shells like pressure vessels, which may incorporate extruded nozzles and other design features. With cold forging of steel rod, wire, or bar, shaft-like parts with 3-plane bends and headed design features are not uncommon. Hot forging prevents the work hardening that would result from cold formingwhich would increase the difficulty of performing secondary machining operations on the piece. By controlling the compression rate of the press forging operation, the internal strain can be controlled.


  • Forging is a manufacturing process involving the shaping of metal using localized compressive forces. The blows are delivered with a hammer (often a power. HYFC Ti-alloy forging for Rolls-Royce HYFC Landing Gear Forging HYFC.

    There are basically three methods (or processes) to make a forged part. Impression Parts from a few ounces to 60, lbs. can be made using this process.
    There are two main types: mechanical and hydraulic presses.

    As a result, the texture variation is continuous throughout the part, giving rise to a piece with improved strength characteristics. Categories : Metal forming. To achieve a low-cost net shape forging for demanding applications that are subject to a high degree of scrutiny, i.

    Retrieved 1 October Generally, the cold forming operation will do the finishing stage so that the advantages of cold-working can be obtained, while maintaining the high speed of automatic hot forging.

    There are times when warm forging practices are selected over cold forging especially for higher carbon grades of steel or where in-process anneals can be eliminated.

    Another variation follows the same process as outlined above, except the preform is produced by the spraying deposition of metal droplets into shaped collectors similar to the Osprey process.

    Another reason forgings are common in these industrial sectors is that forgings generally have about a 20 percent higher strength-to-weight ratio compared to cast or machined parts of the same material. Some of the smaller parts are actually forged cold. The major advantage to this process is that less metal is lost to flash.

    If the basic disciplines are not met, subsequent material removal operations will likely be necessary to remove material defects found at non-destructive testing inspection. The principle behind the machine is simple: raise the hammer and drop it or propel it into the workpiece, which rests on the anvil.

    Once the proper thickness is achieved the proper width is achieved via "edging". Due to the nature of this type of system, different forces are available at different stroke positions. The following cavities are called "blocking" cavities, in which the piece is working into a shape that more closely resembles the final product.

    Part geometry's range from some of the easiest to forge simple spherical shapes, block-like rectangular solids, and disc-like configurations to the most intricate components with thin and long sections that incorporate thin webs and relatively high vertical projections like ribs and bosses.

    The dies are usually flat in shape, but some have a specially shaped surface for specialized operations.

    If there is only a short run of parts to be done, then it may be more economical for the die to lack a final impression cavity and instead machine the final features.

    The final shape is forged in a "final" or "finisher" impression cavity. Even though basic shapes with rectangular cross-sections are the norm, rings featuring complex, functional cross- sections can be forged to meet virtually any design requirements. Views Read Edit View history.

    1. Also, while work hardening may be desirable in some circumstances, other methods of hardening the piece, such as heat treatingare generally more economical and more controllable. Hollows cylindrical in shape, usually with length much greater than the diameter of the part.

    2. The operation is a time-consuming process due to the amount and length of steps. Forged parts can range in weight from less than a kilogram to hundreds of metric tons.

    3. The workpiece will cool faster because the dies are in contact with workpiece; the dies facilitate drastically more heat transfer than the surrounding atmosphere.

    4. For the hearth used in that process, see forge. Drop forging is a forging process where a hammer is raised and then "dropped" onto the workpiece to deform it according to the shape of the die.
