Improving the production process of motorcycle crankshaft case study of Revaltech Thailand

Abstract

This research is to improve the production process of motorcycle crankshaft. A case study of Revaltech Thailand with insufficient production capacity, which has 32 steps in the production of motorcycle crankshaft. There will be processes that are wasted, such as the process of walking to get the material or the process of waiting for the material. and complex machine placement causing the production process to be delayed these processes cost time and distance. Therefore, the authors have introduced flow process charts (FPC), 5W1H questioning techniques and ECRS problem solving principles. In order to modify the production process of motorcycle crankshaft from the original 32 production steps and the production process was reduced to be suitable for 29 steps and when tested and then used to assess the situation that will occur. Yes, such as reduced process, reduced time, reduced distance, time to manufacture end parts. motorcycle crankshaft, the mean time is 1,481 seconds. and after the adjustment was 1,339 seconds, with the result after the comparison was 141 seconds. which accounted for 26.67% when the process of improving the production process of the crank end parts of the motorcycle crankshaft can be reduced It will increase efficiency in the production process as well. Improving the production process of motorcycle crankshaft case study of Revaltech Thailand. Consider the suitability in the process of improving the production flow chart of motorcycle crankshaft.
