Casting and foundry processes are specifically designed to transform raw materials, typically metals, into objects with specific shapes in a single step. This is accomplished by pouring molten material into a pre-shaped mold, where it cools and solidifies, taking on the shape of the mold. This process is particularly advantageous for creating complex shapes and large components that would be difficult or impossible to achieve through other means, such as machining.

Forging, while it does shape materials, typically involves heating the material and then reshaping it through hammering or pressing, which often requires multiple steps. Welding is a process of joining two or more materials, generally metals, together through melting and fusing, which also requires additional steps for preparation and finishing. Extrusion, on the other hand, involves pushing material through a die to create long shapes, like tubes or pipes; this is effective for continuous shapes but may not cover the same range of complex geometries that casting can.

The ability to create intricate shapes in one step is fundamental to the casting method, making it a critical technique in manufacturing and construction industries.
