Abstract: A finite element analysis （FEM） simulation model for large arc of International Thermonuclear Experimental Reactor (ITER) Side correction coils by molding was established. Processes including molding and spring-back effect after being molded were simulated. The distribution of stress, strain on the inner and outer faces of conductor were gained, and the value of spring-back after being molded was obtained. One set of molding equipment was designed and manufactured, and the value of spring-back with molds of different radiuses by using this equipment was obtained. The experimental results show that the FEM simulation model is correct and molding is a feasible method for the manufacturing of ITER Side correction coils.
