Abstract
Warpage is one of the most frequent issues facing the molding industry, especially for different wall thickness products. The aim of this study is to generate an optimization method in order to reduce warpage of a protector cover as much as possible. Topology optimization and deflection analysis were carried out to obtain a stiff design that resists warpage. The topology optimization results suggest a weak area/void in the product design. Then, a careful consideration in patterning the rib location and modification wall thickness based on topology data was introduced until it obtained an optimum wall deflection. Finally, the warpage conditions were found to optimize approximately 79.52% (left side), 76.12% (middle area), and 69.06% (right side) with respect to the reference model.
