Die casting is a manufacturing process where molten metal is forced into a mold (called a die) to create precisely shaped metal parts. It's commonly used in automotive manufacturing to make parts like engine blocks, transmission cases, and other vehicle components. Think of it like a sophisticated version of making ice cubes - instead of water in an ice tray, it's molten metal being poured into carefully engineered molds. This process is popular because it can quickly produce many identical parts with high accuracy and smooth finishes. When you see this term in resumes, it usually indicates experience with either operating die casting machines, designing the molds, or managing the production process.
