Implantação da metodologia dmaic para redução de desperdícios em uma indústria de embalagens plásticas

Abstract

Currently, the companies increased the attention with the sources of waste present in their production systems. In plastic packaging companies this attention occurs more effectively, mainly because the plastic material has an unfavorable reputation on environmental issues. In addition, high competitiveness in the industry requires processes with high quality and low variability. Thus, the concept of Six Sigma fits perfectly in this context, since it seeks to structure and monitor the quality and stability of the processes developed, most often using statistical tools of control. The DMAIC is a strong methodology coupled with the Six Sigma approach, generally used in experimental projects. Thus, the present work had the objective of implanting the DMAIC methodology in a plastic packaging industry, aiming at proposals for improvements to reduce the company's waste indexes. These indices were obtained through the data, meetings and spreadsheets made available by the company under study and were used in the implementation stages of the DMAIC. In the study, the products were divided into three lines, and the line with the highest loss index was selected for application of the DMAIC methodology. Deployment detected that the wastage indices of the chosen line varied according to existing machines and shifts. As a proposal for improvement it was suggested to adopt the failure analysis and the use of the product FMEA initially for the product of the line that presented the greatest variation in the results. The improvements adopted should be monitored and controlled through FMEA indices, in order to detect remaining problems and seek long-term waste reduction, as the DMAIC aims
