Casting is a manufacturing process where liquid metal or other materials are poured into a mold and allowed to solidify into a specific shape. It's like making ice cubes, but with metal - you pour the hot liquid metal into a shaped container, let it cool, and get the final product. This method is widely used to create everything from car parts to building materials. Companies use different types of casting methods, such as die casting (using metal molds) or sand casting (using sand molds), depending on what they're making and how many pieces they need.
