Abstract:
This research aimed to apply industrial engineering techniques to reduce loss from air hose cutting process at an example automotive part factory. The discarded raw material average cost amount of 221,870 Baht per month.
The researcher applied industrial engineering techniques comprising of QCC, 7 Wastes, 7 QC Tools with Pareto chart to select the product to be studied, 7 New QC Tools with Tree Diagram to search for a problem solving method, waste reduction by ECRS as well as jig and fixture design.
As the result, it is found that the fixture allowed the forming process to the exact required dimension. Therefore, no more discarding the raw materials which accounted for 100% loss reduction or saving 221,870 Baht per month. The payback period is 1.2 production days.
