Computer based simulations can be used to design and optimize commonly used industrial dies thereby reducing the need for costly modifications of a poorly designed die. Strategies are presented for the design and optimization of three types of extrusion dies, a mandrel pipe die, a spiral blown film die, and a coat‐hanger sheet die. The development of the computer model for each of the dies is presented. The assumptions made in the model and the numerical techniques employed in each of the simulations are outlined. Numerous examples are given to illustrate how each of the design simulations is used.
