Abstract
A polymer processing design methodology is presented which can be used to improve the production of plastic components manufactured via the extrusion and injection molding processes. The design method combines polymer process modeling, design sensitivity analysis, and numerical optimization. It is applicable to systems with creeping flow of purely viscous non-Newtonian fluids through thin cavities where the lubrication approximation can be applied. Analytical sensitivities are computed via the adjoint method for performance measures defined on the pressure and residence time fields and via, the direct method for the transient mold filling simulation. Sheet extrusion dies and mold designs for injection molding are optimized to exemplify the polymer processing design methodology.
