This article aims to outline the key differences between casting and forging, exploring the mechanics of each process, their respective advantages and disadvantages, and their applications across various industries.

The Fundamentals of Casting

Casting is a process where molten metal is poured into a mold and allowed to solidify into a desired shape. The fundamental steps include melting the metal, preparing a mold, pouring the molten metal into the mold, and finally allowing it to cool and solidify. Once the metal has set, the mold is removed, and the casting is often subjected to further processing like trimming, grinding, or machining to achieve the desired finish.

One of the significant advantages of casting is its capability to create complex shapes that would be challenging to produce using other methods such as forging or machining. The flexibility in design allows for intricate details, cavities, and the ability to produce components that are large or small in scale.
