This studies for production of plastic bottles by choose 600 cc. plastic bottles size, use spiral and round form. To know production of plastic bottles and find standard time with start until finish production of plastic bottles, including developing production of plastic bottles system. By used the ECRS concept and theory for process analysis, and study time directly in problem cause from the cause of wasting time on the move. Some sub can including step work together. Solutions to problems is reduced mobility or moving work unnecessary, and moving breakpoints pre-form box, put on closing with mechanism from reduced mobility moving pre-form box. And reduces the area working. The effect from studies after improved was from 17 to 14 step reduce, working distance 44.9 to 35.1 meter reduce. And had standard time 229.11 to 197.33 second reduce. And then, make sure that production improvement by used ECRS can reduce production time in 13.87 % reduced.
