time of expander is reduced and output balancing is achieved between the expander and the auto-brazing machine, necessary adjustment should be made in the capacity of lean testing operation by addition of testing stations. Finally, the layout of coil shop should be modified to facilitate storage of tested coils, once the entire process is balanced. There is no need of storage facility for storing semifinished coils. Necessary changes should be made in the material handling and storage system. VSM suggestion can be implemented in two phases. In the first phase, setup of expander machine can be reduced by SMED techniques. In the second phase, the cycle time balancing can be done among expander, auto-brazing, and leak testing machines. The layout can be modified to create more space and storage racks can be moved at the end of a shop to store coils for assembly.
