Die casting is a metal casting process in which a pressurized mold, or 'die,' is used to produce complex metal parts, or 'casts,' with high degrees of accuracy and consistency. Typically, die casting uses non-ferrous metals (those that do not contain iron), such as aluminum, zinc, magnesium, or copper. The process is used in a wide variety of industries to produce parts that are fit for production or end-consumer use. It is similar to injection molding, which essentially uses the same process, except with molten plastic rather than metal.
