Die-casting is a fast, versatile and cost-effective manufacturing process for producing complex-shape metal components by injecting liquid metal at a high pressure in a steel mold called a die. Die-castings are among the highest volume, mass-produced items manufactured by the metalworking industry, and they can be found in thousands of consumer, commercial and industrial products. The die-casting process typically uses a non-ferrous alloy, such as aluminum and zinc, which is melted in the furnace and then injected into the die; the die is installed on a die-casting machine.A die, or mold as it is sometimes called, is an essential requirement for manufacturing parts with the die-casting process. The die-casting die is said to be the back-bone of die-casting process, and greatly influences the cost, rate of production and quality of the parts produced. Designing a die for die-casting is a non-trivial and time consuming process that requires vast technical know-how and experience of a die designer. A die-designer has to go through a number of steps, all of which involve critical decision making, taking into account multiple factors, such as part material, production and delivery requirements, process requirements, die-design knowledge, and industry best practices. The non-triviality of the die-design activities further increases manifold in case of a multi-cavity die, which are commonly used in the industry.
