Estudo de caso do desempenho de uma empacotadora automatizada em linha de tubos de uma indústria metalúrgica

Abstract

Packaging in industrial lines can represent a critical point for production flow continuity, especially when the end of the line limits operational performance. This study aimed to analyze the performance of the automated packaging system associated with Tube Machine 04 (MT04), in a metallurgical industry, considering its effects on productivity, interruptions, operational efficiency, safety, ergonomics, and internal logistics. The research was developed as a case study, with a quantitative and qualitative approach, using internal data from January to November 2025. The analysis compared two periods: January to June, prior to the stabilization of the packaging system, and July to November, after its stabilization. Production indicators, interruptions, OEE, Availability, Performance/Efficiency, and Quality were evaluated, in addition to a Pareto analysis applied to interruptions more directly related to the end of the line. The results indicated a 13.1% reduction in the monthly average of interruptions, an increase in OEE from 33.62% to 39.21%, and growth in consolidated production from 24.2 thousand to 31.8 thousand tons. A lower operational exposure to manual activities related to bundle forming and strapping was also observed. It is concluded that the post-stabilization period showed improved operational performance of MT04, without attributing the results exclusively to the automated packaging system.
