Die design is one aspect of extrusion engineering that has remained more of an art than any other aspect. The obvious reason is that it is difficult to determine the optimum flow channel geometry from engineering calculations. Realistic analysis of flow through dies in many cases requires computation of three-dimensional velocity profiles inside the die.
