Minimization of warpage of injection-molded parts through ideal wall thickness distribution - a feasibility study
The injection molded parts warpage, represented by the geometric difference between the actual and the target part, is a permanent problem during the development of new injection molded parts. While most efforts to reduce the part warpage have resulted in optimization of the processing parameter and gate location, this study presents a method which aims to reduce the part warpage by optimization of its wall thickness distribution. This method is based on an evolutionary optimization algorithm, which interacts with the injection moulding simulation. The procedure is fully automatic and results in a STL-File for the optimized geometry of the cavity. The objective of the present study is to evaluate the effi-ciency of this method for a non-complex geometry.
