Implementação de Single Minute Exchange of Die (SMED) para uma linha de solda de tanques

Abstract

In the scenario of a competitive and globalized world, the corporations act requires that actions aimed at increasing the productivity, the ability to respond more quickly to customers and to minimize cost, it will be put into effect. In this context, the reduction of setup time is also called a single minute tool change (SMED – Single-Minute Exchange of Die). Therefore, the general objective of the study was to analyze the process of manufacturing tanks, related to the manufacture of components in the solder of tanks (MDF2 line), of a metallurgical company, located in Blumenau/SC, proposing actions for improvements to minimize the time of setup The study involved biliographic research, quantitative research and the Case Study.The data was collected in 2019. The results showed that for the tank section, the reduction in time with activities that do not add value after the work of the delivery of the welding wire was 1022.2 h/year and the gain was R$ 25,421.24. In addition, to propose actions to reduce the time of setup through the SMED concept, focusing on increased productivity, notably the EPI (individual protection equipment) delivery process. Deliveries of EPIs were proposed on a weekly basis, thus preventing the operator from having to leave his workstation and look for them. A route and a schedule were also drawn up. In this context, with the work of delivering the welding wire and delivering EPIs, a large reduction in activities that do not add value in the Tanks section was achieved, with gains of R$ 25,421.25 and R$ 21,622.88, totaling a total gain for the Tanks section of R$ 47,04 4.13.
