Forging Process

Forging is a metal working process by which metal & alloys

are plastically deformed reduced to the desired shape by the

application of a compressive force.

Closed Die Forging

As the name implies, two or more dies containing impressions of the part shape and brought together & forging stock

undergoes plastic deformation. Because metal flow is restricted by the die counters, this process can yield more

complex shapes & closer tolerances than open die forging process . Additional flexibility in forming symmetrical & non

symmetrical shapes comes from various forming operations ( sometimes bending ) prior to forging in finisher dies. There

various geometrical product possible with forging process range from some of the easiest to forge simple spherical shapes,

block - like rectangular-solids, & disk like configurations to the most intricate components with thin & long section that

incorporate thin webs & relatively high vertical projections like ribs & embossing . Although many parts are generally

symmetrical, others incorporate all sorts of design elements ( flanges, protrusions, holes, cavities, pockets, etc. ) that

combine to make the forging very non - symmetrically. In addition, parts can be bent or curved in one or several planes,

whether they are basically longitudinal, euqi dimensional or flat.

Open Die Forging

Open die forging is performed between flat dies with no precut profiles is that dies .Movement of the work piece is the

key to this method. In this process the product geometry is more depends on the skill of operator.

Process Capabilities

In practice, open die forging comprises many process variations, permitting an extremely broad range of shapes

sizes to be produced. At the high end of the size range, open die forgings limited only by the starting stock, namely

largest ingot That can be cast . Practically all ferrous and non - ferrous alloys can be open die forged.

Not unlike successive forging operations in a sequence of dies, multiple open die forging operations can be

combined to produce the required shape . At the same time, these forgings methods can be tailored to attain the

proper amount of total deformation & optimum grain flow structure, there by maximizing property enhancement &

ultimate performance for a particular application. Forging an integral gear blank & hub, for example, may entail

drawing or solid forging operations, then upsetting. Similarly, blanks for rings may be prepared by upsetting an

ingot, then piercing the center, prior to forging the ring.

Cold Forging

This is a process of plastic deformation of metals at room temperature at the same degrees above that to give then

desired geometrically shapes.

Process Capabilities

Cold forging encompasses many process bending, cold drawing, cold heading coining, extrusion, punching, thread

& more to yield a diverse range of part shapes. These include various shaft-like components, cup-geometry, hollow

with stems & shafts, all kinds of upset ( headed ) & bent configurations, as well as combinations.
