Setup time reduction in pvc boots production through smed technique

Abstract

The competition imposed by the market requires of the organizations the continuous improvement of its processes, products and offered services, with lower production costs. This article addresses this issue describing the resulting improvements from the implementation of Single Minute Exchange of Die (SMED) in the process of exchange the mold of the injection machine of PVC during the boots manufacturing. The case study was conducted in a large company of footwear, located in the state of Paraiba. In order to find the best alternative to the problem of the setup of the molds, were used the SMED and the methodology for problem resolution, and then was implemented the solution that generated greater productivity for the company. Among the improvements made, we should emphasize the reduction of inactive time of 11.56 minutes to 5 minutes, reducing the time needed for the adjustments of the molds with the implementation of guides for centering and shims to standardize the heights of the molds.
