Difference Between Cast and Forged | Difference Between
Definition of Cast vs. Forged. Casting is a metalworking process where the metal is first heated to a melting point, then poured into a mold to obtain the desired shape. Forging, on the other hand, is a process whereby compressive forces are used on the solid material in order to achieve desired shapes.
