Forming parts by pressure
Introduction
We have studied forming parts by machining and by casting. Parts may also be formed to the desired shape by forging, by the process of powder metallurgy, and by the process of pressing from metal sheets.
While each of these processes differs in the method of manufacture, there is a definite similarity. In each case, pressure must be applied to a form of metal, thus forcing or squeezing the metal into cavities which form the shape of the metal parts. The metal may be hot or cold or even powdered at the time the pressure is applied.
