Abstract：In the traditional design concept of foundry technologists, it is generally believed that under the premise of ensuring the quality of castings, the larger the volume of the pouring cup applied, the more metal liquid it consumes, and the lower the effective utilization rate of metal liquid. Meanwhile, the corresponding pouring time is prolonged with increasing volume of the pouring cup, resulting in low production efficiency and poor economic efficiency. However, this paper mainly studies the related process technology in reverse thinking. In view of the low utilization rate and production efficiency of molten metal using a common pouring cup, simulations of the filling and solidification processes of both the common pouring cup and the bigger pouring cup were conducted using MAGMA software, and then comparative research was carried out. The results show that using a bigger pouring cup can significantly improve the production efficiency of DISA casting production lines, with prominent improvement in the efficiency of molding and pouring per unit time, which proves that it has high promotion value in casting enterprises.
