4. Drop Forging

Drop forging is a metal shaping process, the metal to be formed is first heated then shaped by forcing it into the contours of a die, this force can be in excess of 2000 tons. The drop forging process can be performed with the material at various temperatures. Hot Forging: During hot forging the metals are heated to above their recrystallization temperature. The main benefit of this hot forging is that work hardening is prevented due to the recrystallization of the metal as it begins to cool. Cold Forging: Cold Forging is generally performed with metal at room temperature below the the recrystallization temperature. Cold forging typically work hardens the metal. There are two types of drop forging, open die and closed die. Open die drop forging requires the operator to position the work piece while it is impacted by the ram. The die attached to the ram is usually flat or of a simple contour, most of the shaping is achieved by the operator physically positioning the work piece before each stroke of the ram. There are also special dies which can be used to cut the metal, form holes or notches.

7. Open Die Forging

Open-die forging is also known as smith forging. In open-die forging, a hammer strikes and deforms the workpiece, which is placed on a stationary anvil. Open-die forging gets its name from the fact that the dies (the surfaces that are in contact with the workpiece) do not enclose the workpiece, allowing it to flow except where contacted by the dies. Therefore the operator needs to orient and position the workpiece to get the desired shape. The dies are usually flat in shape, but some have a specially shaped surface for specialized operations. For example, a die may have a round, concave, or convex surface or be a tool to form holes or be a cut-off tool. Open-die forging lends itself to short runs and is appropriate for art smithing and custom work. In some cases, open-die forging may be employed to rough-shape ingots to prepare them for subsequent operations. Open-die forging may also orient the grain to increase strength in the required direction. Cogging is successive deformation of a bar along its length using an open-die drop forge. It is commonly used to work a piece of raw material to the proper thickness.

14. Hot Forming

Hot forging is the plastic deformation of metal at a temperature and strain rate such that recrystallization occurs simultaneously with deformation, thus avoiding strain hardening. For this to occur, high workpiece temperature (matching the metal's recrystallization temperature) must be attained throughout the process. A form of hot forging is isothermal forging, where materials and dies are heated to the same temperature. In nearly all cases, isothermal forging is conducted on superalloys in a vacuum or highly controlled atmosphere to prevent oxidation.

34. Stainless Steel Forging

Virtually all metals that can be moulded / drawn out may be forged by first heating and then hammering it in to the desired shape. A billet, wrought bar, cast or sintered ingot etc.. may be forged. Forging improves the toughness and strength of improving orientation of the metal grain structure. The repeated heating and hammering causes the metal to become more dense and the grain "flow lines" to follow the contour of the end product.

58. Bearing and Housing Units

Bearing and housing units, often referred to as mounted bearings or bearing units, are complete assemblies that consist of a bearing and a housing designed to work together as a single, integrated unit. These units are used to provide support and secure rotating shafts or components in various industrial and machinery applications. Bearing and housing units simplify installation, improve bearing performance, and enhance overall machine reliability. Bearing and housing units are used in a wide range of applications across industries, including conveyors, fans, pumps, agricultural machinery, and more. They simplify the design and installation of rotating components, reduce maintenance requirements, and improve the overall reliability of machines and equipment. The choice of a specific bearing and housing unit depends on factors such as load capacity, speed, environmental conditions, and the mounting requirements of the application.

59. Cold Forming

Cold forging is a high speed manufacturing process whereby metal is shaped at room temperature often without the need for the removal of material. A simple blank is placed within a die and a punch is pressed into the blank. The blank then takes on the form of the punch and the die. By utilising multiple dies and punches in succession very complex shapes can be achieved. Metal is forced beyond its yield (elastic) limit and retains its altered shape upon removal from the die. The metal is not forced beyond its tensile strength, otherwise fracturing would occur (the exception is when trimming or piercing). Historically cold forming has been an experienced based technology, but this is changing as new computer based analytical tools are constantly being developed.

75. Press Forging

Press forging works by slowly applying a continuous pressure or force, which differs from the near-instantaneous impact of drop-hammer forging. The amount of time the dies are in contact with the workpiece is measured in seconds (as compared to the milliseconds of drop-hammer forges). The press forging operation can be done either cold or hot. The main advantage of press forging, as compared to drop-hammer forging, is its ability to deform the complete workpiece. Drop-hammer forging usually only deforms the surfaces of the workpiece in contact with the hammer and anvil; the interior of the workpiece will stay relatively undeformed. Another advantage to the process includes the knowledge of the new part's strain rate. We specifically know what kind of strain can be put on the part, because the compression rate of the press forging operation is controlled.

78. Hot Forging

Hot forging is the plastic deformation of metal at a temperature and strain rate such that recrystallization occurs simultaneously with deformation, thus avoiding strain hardening. For this to occur, high workpiece temperature (matching the metal's recrystallization temperature) must be attained throughout the process. A form of hot forging is isothermal forging, where materials and dies are heated to the same temperature. In nearly all cases, isothermal forging is conducted on superalloys in a vacuum or highly controlled atmosphere to prevent oxidation.

96. Steel Forging

Virtually all metals that can be moulded / drawn out may be forged by first heating and then hammering it in to the desired shape. A billet, wrought bar, cast or sintered ingot etc.. may be forged. Forging improves the toughness and strength of improving orientation of the metal grain structure. The repeated heating and hammering causes the metal to become more dense and the grain "flow lines" to follow the contour of the end product.

118. Upset Forging

Upset forging increases the diameter of the workpiece by compressing its length. Based on number of pieces produced this is the most widely used forging process. A few examples of common parts produced using the upset forging process are engine valves, couplings, bolts, screws, and other fasteners. Upset forging is usually done in special high-speed machines called crank presses, but upsetting can also be done in a vertical crank press or a hydraulic press. The machines are usually set up to work in the horizontal plane, to facilitate the quick exchange of workpieces from one station to the next. The initial workpiece is usually wire or rod, but some machines can accept bars up to 25 cm (9.8 in) in diameter and a capacity of over 1000 tons. The standard upsetting machine employs split dies that contain multiple cavities. The dies open enough to allow the workpiece to move from one cavity to the next; the dies then close and the heading tool, or ram, then moves longitudinally against the bar, upsetting it into the cavity. If all of the cavities are utilized on every cycle then a finished part will be produced with every cycle, which makes this process advantageous for mass production.
