Abstract: This paper introduced the mixed-line production of 15 kinds of casting in three workshops of Yu-chai foundry. Because the sand:iron ratio is very different causing the management problem of molding sand, we analyzed the influence of mixed-line production by models of extreme sand:iron ratio in cylinder block or cylinder head on molding sand system, and the methods of solving quality problems of avalanche sand. From the perspectives of molding sand’s material balance and circulatory system control, the reasons leading to the disorder of molding sand system using mixed-line production by models of extreme sand:iron ratio were analyzed. Furthermore, the me-thods, which could solve the problem of mixed-line production by models of extreme sand:iron ratio through system control, were proposed. Production scheduling should be adjusted by following the sand cycle rules, and molding sand ratio should also be adjusted according to the actual cir-cumstance of various models. Through the stabilization of molding sand’s available soil, available braize and silt content to guarantee the stability of molding sand, we have earned experiences of mixed-line production by different models of extreme sand:iron ratio.
