In this study, the interactive effects of the process parameters involved in the production of copper tubes using the Upcast casting method at Babak Iranian Copper Company were investigated. The main objective of the research was to optimize product quality and reduce process interruptions. For this purpose, the Central Composite Design (CCD) method was employed to analyze the combined influence of various process parameters such as melt temperature, withdrawal speed, immersion height, water flow rate, and the dimensional difference between the mold and the cooling system. The results of analysis of variance indicated that melt temperature, the dimensional gap between the mold and the cooling system, and immersion height exert the greatest influence on the tensile strength of the products and the location of the solidification front. Furthermore, the mutual interactions between these parameters were examined, revealing how variations in each parameter affect the final quality of the produced tubes. Ultimately, by identifying the key influential parameters, a strong foundation was established for quality control of the production process, enabling effective improvement of product quality and process efficiency.
