Optimization of 3D die extrusion using response surface method

Résumé

The primary objective of the geometrical design of extrusion dies in polymer processing is to obtain a uniform velocity distribution across the die exit. A design procedure for complex coat-hanger die is presented. While optimizing the exit velocity distribution, geometric constraints are applied. Three dimensional extrusion simulation software REM3D ® is used to simulate the flow in this flat die. An objective function is defined as the global relative between velocity in exit die and the average exit velocity. This objective function is minimized by varying the flow channel cross-section. For this minimization the global response surface method with Kriging interpolation is used.
