With the increasing demands for fast, effective, and reliable mold design in automotive casting products, the Computer Aided Engineering(CAE) plays an important role in reducing cost and development time of a product and acheiving high quality products in a competitive market. Through the CAE application, the casting processes such as solidification and filling can be simulated for predicting the microstructure and shrinkage defects in the products. In this paper, the subject of study is a rear cylinder in the automotive brake system. Through the numerical simulations carried out using the MAGMAsoft, the optimum riser and neck dimensions influencing on the soundness of Ductile Cast Iron(DCI) castings are obtained. The new design based on optimum dimensions reduces the riser volume up to 30% in comparison with the current design.<br/>
