Melhorias de um processo produtivo a partir do mapeamento do fluxo de valor em uma indústria de esquadrias de alumínio do oeste do paraná

Abstract

A strong competition in productive markets makes the companies seek for new ways of production in order to reduce costs, eliminate waste, improve productive processes and maximize the final results. Thus, Lean Manufacturing contributes to reach more efficient and effective production, eliminating waste and seeking for continuous improvement as well as adding value to the final product. This study aims to apply one of the Lean Manufacturing tools, value stream map, to reach improvements in the productive process of aluminum frames industry, located in the western region of Paraná. This study is classified as an applied research, because it involves a study applied in a company, qualitative because it is the observation of the productive process, exploratory, since it tends to form hypotheses of possible improvements through the observation of the productive process and case study by Involve an in-depth and exhaustive study of an object of study. The data collection was made from direct observations of the production process and information reported by the production managers. From this, a flow map was created of the current state where it was possible to identify wastes related to waiting, transport, stock, movement and rework of products. Thus the future state value stream map can be created aiming at leveling production times, leveling the production rate to takt time, and establishing the unitary and continuous flow of products, thereby reducing some of the wastes found. In addition, the cause-effect diagram was applied to identify the causes of the wastes of rework. Finally, it was noted the importance of the application of Lean Production in the production processes, providing continuous improvement and aggregation of value to the products.
