Metal forging and casting can create a similarly effective product and used as a substitute for each other. Because of this, these two processes are easily confused, and each used for different applications. but the properties of each process are different.
Forging Vs Casting
Forging is to form a shape by heating and hammering. When a material is forged, a piece of metal is being moved or “beat into shape” while still in its solid form. This takes a lot of force to accomplish. The greater the size of the metal the more force needs to be exerted for the same result. Materials used in forgings most commonly include
Casting is to receive a form in a mold. Molten or liquid metal is poured into a mold (either closed or open) and cooled to a solid state where it holds its shape. Casting tends to be most practical for larger applications. Materials best suited for casting are steel, brass, iron, aluminum, and tin. Casting tends to be generally cheaper than forging, but there are many methods of casting, including investment casting; die casting; permanent mold; and vacuum process molding, which can all affect pricing, tensile strength, and cosmetic appearance.
