Design for Forgings
Forging is the process in which metal, cold or heated, is shaped into a component geometry through the use of multiple
blows with a drop hammer or through the application of pressure with a hydraulic press. For most forging processes, a set of dies are required. Due to grain
orientation , forgings are a desirable choice when high strength and excellent fatigue life is required for the component. Many materials can be forged
including aluminum and steel.
There are four major types of forgings used in industry: - Hand, Blocker, Conventional, and pressed.
Conventional and blocker forgings are the most common. Forgings have several advantages over other manufacturing processes such as plate, and castings. The
ability to control the produced part grain direction relative to the applied stresses will produce superior components. High strength, extended fatigue life and
produced component repeatability are advantages of grain direction control.
Many factors need to be considered by the designer in the selection of the appropriate forging process and include:
size, geometry, complexity, quantity, material, component cost and component tolerances. Always consult with the manufacturer for their recommendations in selecting
the appropriate forging process for your particular application.
