The presented contribution points out the possibilities of solving the inlet system, as one of the important factors influencing the final quality of the castings. Due to its design and function, the sprue system influences the process of filling the mold cavity. With the correct design of the sprue system, we achieve the continuity of filling the mold cavity and the elimination of qualitative and quantitative errors caused by non-observance of basic principles in the design of sprue systems. When conducting the experiments, we monitored the mold inlet system, modeling the process of filling the mold cavity and the speed of the liquid metal in the notch and the mold cavity. The results of the experiments show that the speed of the liquid metal when filling the mold is approximately half of the calculated theoretical value.
