Aplicação da metodologia SMED para redução no tempo de setup em uma indústria de aerossóis

Abstract

In a globalized and highly competitive scenario, operational efficiency plays a crucial role in the competitiveness and survival of companies. Faced with the challenges companies face in optimizing their production processes, the implementation of methodologies, philosophies and techniques focused on eliminating waste becomes crucial. In the context of the continuous search for improvement and efficiency in industrial operations, reducing setup times has emerged as a strategy for transforming complex setups into more agile and efficient processes, adapting to the variety of products and the need for frequent productions changes. This research was carried out in three main stages: mapping the current setup process, implementing the steps of SMED (Single-Minute Exchange of Die), known as Quick Tool Change and analyzing the results obtained through setup time indicators and Overall Equipment Efficiency (OEE). A comparison was made between the scenarios before and after applying the SMED methodology. After applying the SMED methodology, the results showed a reduction in the average setup time of the production line, from 47.41 minutes to 39.33 minutes, representing a decrease of 17.05%. The line’s availability index increased by 2.67%, showing greater efficiency in production utilization. In addition, the overall OEE of the production line increased by 18.91%, consolidating the benefits of standardizing and optimizing the process. It can therefore be concluded that the application of the SMED methodology has led to improvements in the process of the production line under study.
