What is Forging?

Forging is a manufacturing process through which a solid metal workpiece is deformed and then re-shaped using compression. Unlike other methods of shaping metal, forging gives the creator more control over the final result because the grain of the metal deforms to follow the new shape. This means that the forger can decide which parts of the new metal object will be the strongest. As a result, a forged piece is stronger than the same piece created through casting or machining.

Different tools are used to accomplish forging, including the more traditional hammer and anvil, as well as the industrial use of hammers powered by electricity, steam, or hydraulics. Today, forging is largely done by machines at the industrial level and is a worldwide industry.

Forging is done either, ‘hot,’ ‘warm,’ or ‘cold.’ No matter the temperature, the method and machines used can be classified as one of the following:

Drop Forging: Use of forging hammers and screw presses

Pressure Forging (rotational motion): Use of hydraulic and mechanical machines

Pressure Forging (translational motion): Use of rolling mills

Pressure Forging (a combination of translational and rotational motion): Flospinning and orbital forging
