4.2 VSM—future state
Table 5 shows the proposed method of setup. Figure 13 is the projected view of expander machine after implementation of the Kaizens.
After performing data analysis and reducing the setup time of the expander, which was an incentive for making further improvements sequentially, the future state of the coil shop is determined. Once the setup time is reduced, the line balancing should be done between expander and auto-brazing by decreasing the speed of auto-brazing machine. After increasing the output of expander, sequential facility addition should be made for leak testing to balance the entire value chain.
As shown in Fig. 14, the layout of the coil shop is modified. The distance between auto-brazing and expander machine is reduced since space is not needed to store WIP between the machines. In addition, the storage racks are placed at the end of the coil shop to store finished coils Number of coil testing
