<p>Simulation, as one of the important methods in developing and reducing manufacturing costs, can be considered in various industries, including casting. This research is focused on the simulation of the casting procedure for a valve housing in the automotive industry with the AlSi₉Cu₃ alloy to improve efficiency, cut down expenses, and decrease material loss. CATIA was employed to create an accurate 3D representation of the hydraulic valve housing, while JMatPro and Click2Cast were utilized for the simulation. A physical prototype was developed to confirm the results by comparing strength and hardness, which confirmed the accuracy of the simulations. The results showed that simulation can be an important method for material design, and more than 85 percent of the simulation results matched the actual manufactured sample. The results of the actual modeling also showed that the AlSi₉Cu₃ alloy exhibits a relatively uniform microstructure and can report relatively similar properties compared to a similar alloy (A356).</p> Graphical Abstract <p></p>
