Die casting is a high precision, rapid parts-production process involving the high pressure injection of molten metal into a die having a cavity of the desired part shape. To better understand the versatility of die casting, this program explores the common die cast metals and their various properties, as well as die casting machines and die cast tooling. Using shop floor footage and animated sequences the machine section covers in detail the hot-chamber and the cold-chamber machine types. Also discussed is the importance of lubrication in die casting, the use of accumulators and pressure intensifiers, and machine controls and automation. The tooling section examines the various die production materials and techniques. In addition, terms such as cover die, ejector die, fixed cores, core pulls, venting, die cooling, and draft angles are clearly defined.
