Abstract:
The objective of this research is to improve productivity for cast iron burner production line from 5,000 to 8,000 sets per month by eliminating and reducing non-value added task including bottle neck, wastes from delay, excess motion, defect, rework as well as decreasing raw material transportation distance.
This research implements 7 Wastes, 7 QC Tools for data collection and causes analysis. Visual control, line balancing, plant layout, work study and ECRS technique are main tools for production improvement.
The result shows an ability to control cycle time not to exceed takt time for all stations. Working stations are reduced to 7 stations which accounts for 25%. Workers are reduced to 7 persons which accounts for 25%. Total cycle time can be decreased 226.02 Seconds which accounts for 14.33%. The average defect is reduced to 0.13%. The new plant layout can reduce materials transportation distance 416 meters which accounts for 74.42%. Productivity increases 205.60%. The process capacity reaches 8,000 sets per month as desired. The standard time is set for worker.
