Metal casting is a manufacturing process where molten metal is poured into a mold to create a specific shape. The mold is usually made from materials like sand, metal, or ceramic, and it can be designed to produce complex shapes. Once the metal cools and solidifies, the mold is removed, revealing the finished product. This technique is widely used in various industries, including automotive, aerospace, and art. Common metals used in casting include aluminum, iron, and copper. Metal casting allows for efficient production of parts and components, making it a vital process in modern manufacturing.
