Redu o do tempo de setup como estratégia de aumento da capacidade produtiva: estudo de caso em sopradora de garrafas plásticas

The increasing demand for the introduction of new products to serve all customers from different markets causes companies to seek new concepts in planning and programming production and in the changing of tools. Single-Minute Exchange of Die (SMED) reduces the setup time of equipment, minimizing non-productive periods. Thus, it is possible to reduce the size of production batches to increase operating rates and improve the flexibility, productivity and competitiveness of organizations. This paper presents the stages necessary for the implementation of SMED in a plastic bottle blower and reports the results obtained. To achieve this, we conducted an analysis of activities, suggested improvements in the machine and in procedures, timed the stages before and after introducing the improvements and analyzed the times obtained. The results showed a significant reduction in setup time for the machine in this study.
