Forging is a manufacturing process involving the shaping of metal using localized compressive forces. Forging is often classified according to the forging temperature at which it is performed: cold forging, warm forging, or hot forging.
Forging are made from steel alloy, aluminum alloy, copper, brass, bronze, copper, etc.
Forging can produce a piece that is stronger than an equivalent cast or machined part. As the metal is shaped during the forgings process, its internal grain deforms to follow the general shape of the part. As a result, the grain is continuous throughout the part, giving rise to a piece with improved strength characteristics.
Forging parts are widely used not only in kitchenware, hardware, hand tools, edged weapons, cymbals, and jewellery but also in mechanisms and machines wherever a component requires high strength. Some forgings require further processing (such as machining) to achieve a finished part.
The are two main types of forging presses: mechanical and hydraulic forging presses.
