The polyurethane molding process is used in many applications in the automobile industry. It mixes polyol and isocyanate with water, and molds it through a foaming reaction. It is also used in sunroof glass, and is produced through the processes of filling, foaming/expansion, and then hardening and ejection. Recently, sunroof products have become larger in size and more complex, due to designs that consider the openness and design aspects of the vehicle. However, this design trend has a long flow length and complex changes in shape, increasing the risk of appearance defects, such as short shots and air traps and warping defects. In this study, which used CAE, we predicted and improved the appearance defects and warping defects through flow analysis, cooling analysis, and warp analysis of sunroof polyurethane molding. In other words, we verified the consistency of CAE and the experiment by comparing flow patterns. The cause of the air trap was also identified. Furthermore, the causal factors in molding defects, depending on the air trap location, were analyzed, and improvement measures were presented. After predicting the degree of deformation based on the cooling channel, similar CAE results of 80.5 % in the vertical direction, and 90.6 % in the horizontal direction were obtained, proving the validity of the deformation analysis, which can be used as reverse engineering data.
