Forging, the term used for shaping metal into objects, is an old metalworking process that is still widely used today. It produces a much stronger metal than cast or machined metal parts, and offers a high strength-to-weight ratio. There are many types of forging processes, including impression-die forging. Also known as closed-die forging, impression-die aluminum forging, and other alloys can create an endless variety of shapes that can weigh from a few ounces to more than 25 tons. This type of process offers numerous benefits that cannot be created through other methods.

Impression-die forging can produce more complex shapes and closer tolerances than open-die processes. This is because two or more dies containing imprints of the part shape are united during the plastic deformation and metal flow is limited due to the die outlines. Impression-die forging offers great flexibility. Parts can range from symmetrical designs to intricate designs that also include holes and pockets. In addition, impression-die parts can bend or curve in one or many areas. Most metals and alloys can be forged by standard impression-die processes. However, strain-rate and temperature-sensitive materials, such as nickel alloy forgings, may demand high-tech forging processes or special equipment.
