Metal Forging

Commonly known as closed die forging, the impression die forging process uses dies that fully enclose the base material, making it easier to shape the material into the desired form. Unlike other forging methods, impression die forging requires higher compressive forces to ensure the die cavities are completely filled, resulting in the formation of the full part.

Impression Die Forging Advantages

• Generate less metal waste
• Higher production rates
• Provides enhanced fatigue and impact resistance
• Produces parts with higher strength-to-weight ratios

Also known as hammersmith forging, open die forging shapes parts by applying direct force. A hammer strikes the workpiece, which is held in place by two flat dies. The process is called open die forging because the dies do not fully enclose the workpiece. In this method, the dies function more as tools rather than enclosed molds, allowing the metal to be deformed into the desired shape.

Open die forging can produce forgings from a few pounds up to more than 150 tons and is ideal for parts weighing over 200,000 lbs. and 80 feet long.

Open Die Forging Advantages

• Improved fatigue resistance
• Continuous grain flow
• Longer part life
• Increased strength
• Less chance of voids
• Finer grain size

Seamless rolled ring forging typically begins by punching a hole in a thick, round piece of metal, which is then rolled and squeezed into a thin ring shape. This process is ideal for producing ring diameters ranging from just a few inches to 30 feet. Unlike other forging methods, rolled ring forging uses curved dies instead of flat dies, allowing for the creation of ring-shaped components with precision and efficiency.

Seamless Rolled Ring Forging Advantages

• Superior structural integrity
• Increased strength
• Controlled directional flow
• Eliminates welding, inclusions, and porosity
