explain the following metal forming processes i. forging, ii. foundry work

i. Forging is a metal forming process in which a metal workpiece is shaped by the application of compressive forces, using a hammer or a press. During the forging process, the workpiece is placed between a pair of dies, and the dies are brought together to apply pressure and shape the metal. Forging is typically used to produce parts with high strength and durability, and it is often used for the manufacture of automotive, aerospace, and other high-strength components.

ii. Foundry work is a metal forming process in which molten metal is poured into a mold and allowed to cool and solidify, in order to produce a shaped metal part. Foundry work is typically used to produce large or complex parts that cannot be easily produced by other metal forming processes, and it is often used for the manufacture of castings for the automotive, construction, and other industries. During the foundry process, the mold is typically made of sand or another porous material, and it is coated with a refractory material to prevent the molten metal from sticking to the mold. The mold is then filled with molten metal, and the metal is allowed to cool and solidify. Once the metal has cooled and solidified, the mold is broken or removed to reveal the finished part.
