In response to the imperative of enhancing operational efficiency and environmental sustainability, this study employs the principles of Six Sigma to improve maintenance activities for weaving machines in an airbag manufacturing facility. The project's objective is to refine maintenance processes, specifically targeting the elimination of rework resulting from faulty maintenance practices. Following the DMAIC framework, the research identified the root causes of maintenance inefficiencies through the voice of the customer, initiating a structured approach towards optimization. The results demonstrate significant improvements across various parameters. Notably, downtime decreased, productivity increased, and the quality of the finished product improved. Furthermore, the project facilitated enhanced training for mechanics, fostering a culture of continuous improvement within the organization. Importantly, these enhancements have profound positive effects on the environment. By optimizing energy usage and improving mechanical systems, the project reduces carbon emissions and resource consumption, contributing to a more sustainable manufacturing process. However, it's essential to note that the results of the implementation of this project are yet to be measured, with ongoing evaluation essential to determine its full impact on environmental and operational metrics.
