In these forming processes a large amount of energy is applied over a very short period of time. Many metals tend to deform more easily under an extra fast charge application which makes these processes useful for forming large parts outside most metals including those that are otherwise difficult to form.
The parts are formed at a rapid rate, and therefore these processes are also called high-speed forming processes. There are several advantages of using these forming processes, such as the die costs are low, the tolerances easy maintenance, the possibility of forming most metals, and the material does not show spring effect. The cost of producing the components by these processes is low. The limitation of these processes is the need for qualified personnel.
There are three main processes of formation of high energy rates: explosive formation, magnetic formation and electrohydraulic formation. We will discuss these processes.
