This study analyzed the amount of displacement of window wipers according to pressure by using finite element analysis (FEA) with KS standards for aluminum alloy window wipers manufactured by die-casting method. The product design was changed over four steps considering the die-casting process to achieve strength greater than that of the conventional steel window wiper. According to the FEA results, the strength of final aluminum alloy window wiper improved by 55% over that of a steel window wiper, and the weight of the former was less by approximately 45%. Therefore, there is the possibility of module downsizing for driving motor capacity. Further, the cost competitiveness improved, and the manufacturing process of aluminum alloy window wipers was simplified.
