Why Use Forgings?

In simple terms, forging is the process of forming and shaping metals through the use of hammering, pressing or rolling. Forging is often classified according to the temperature at which it is performed: ‘cold’ or ‘hot’ forging.

Open die forging involves the shaping of heated metal parts between a top die attached to a ram and a bottom die attached to a hammer anvil or press bed. Metal parts are worked above their re-crystallization temperatures ranging from 1900°F to 2400°F for steel and gradually shaped into the desired configuration through the skillful hammering or pressing of the work piece.

The forging process has the ability to form the material to the desired component shape, while refining the cast structure of the ingot material, healing shrinkage voids, and improving the mechanical properties of the material. Forging also provides means for aligning the grain flow to best obtain desired directional strengths. Secondary processing,

such as Heat Treatment can also be used to further refine the part.

Forged pieces are stronger than an equivalent casting or machined part. No other metalworking process can equal forging in its ability to develop the optimum combination of properties.
