Incremento de la productividad del área de costura de la línea de producción de calzado escolar en el segmento femenino en Plasticaucho Industrial S.A. Utilizando la metodología de manufactura esbelta

Abstract

The objective of this work was to increase the productivity in the sewing area of the scholar footwear production line in Plasticaucho Industrial S.A through the application of lean manufacturing tools. A family of products was selected for the analysis, four models were chosen for the pilot study. Through the analytical materials course and the criteria of the Value Matrix, the cycle times, the composition of activities and the Efficiency of the Process Cycle of each model were determined; then, a study of the composition of parts, consumption and costs of materials was carried out. In conjunction with the information gathered in the productive area, the aspects to be improved in the sewing process were determined. Based on this, the need to make certain standardizations at the level of pattern design and manufacturing operations was raised. The application of lean manufacturing tools in the analysis of scholar footwear production standards increased the productivity in the balerina belt family by 33.3% per work shift, while the cycle time decreased by 27.9 % per pair. At the conclusion of this work, the applicability of the lean systems is demonstrated as a tool that allows for agile, efficient and innovative processes in favor of customer satisfaction through lower costs and delivery times.
