Die casting is a manufacturing process in which molten metal is forced under high pressure into a mold cavity, also called a "die." The die is typically made of hardened steel and designed to produce precise shapes with intricate details. This method is commonly used for creating components made from metals such as aluminum, zinc, and magnesium. Die casting is widely used in industries like automotive, aerospace, and electronics due to its ability to produce complex, high-strength parts with excellent dimensional accuracy and a smooth finish.
