In this stage, standard time is calculated using work study.
Line balancing is then conducted by reducing the number of workstation to three stations by combining the mould assembly and filling monomer into one station.
Gasket assembly, spring assembly, and filling monomer are also grouped together as a single station. By doing so, the distance of movement is decreased.
One piece flow production can be implemented and the batch size of mould inspection station is reduced by half as shown in Figure 7.
