What manufacturing process involves pouring liquid material into a mold?

Casting is the manufacturing process that involves pouring liquid material into a mold to create a specific shape. This technique is widely used for metals, plastics, and other materials. The mold is typically designed to form the desired final product, allowing the liquid material to cool and solidify within it, thereby taking on the shape of the mold’s cavity.

In casting, the process begins with the preparation of the mold, which can be made from various materials such as sand, metal, or ceramic, depending on the application's requirements. Once the mold is ready, the liquid material is poured in and allowed to solidify. After curing, the mold is removed to reveal the final product.

Forging, milling, and machining involve different processes that do not include pouring liquid materials. Forging typically involves shaping metal through compressive forces, while milling and machining are more about removing material from a solid block to achieve desired geometries. Thus, these processes do not utilize the liquid state of materials like casting does.
