Proposta de otimização do processo produtivo utilizando a filosofia Lean Manufacturing: um estudo de caso em uma indústria de embalagens metálicas

Abstract

With the advent of technology, it was possible to build evolutions in the productive sphere. Many companies were strengthened during the so-called Industrial Revolutions and the new production management concepts that evolved along with them, however, contrary to this reality, a metal packaging company has not taken advantage of such availability in its production line. Given this, this work aims to carry out a case study to raise the main opportunities for improvement of this company and propose solutions for optimization in the process, using the concepts of Lean Manufacturing. The research methodology applied in this work was based on a case study and, for such data acquisition, interviews were carried out with employees, analysis of internal indicators and Value Stream Mapping - MFV that contributed to locate the most critical points of the production chain. With the result of data collection, it was possible to identify opportunities for improvement in the company's production areas, explore possibilities for internal improvement and verify the main bottlenecks in the production system. In this way, an understanding of the process was carried out, the mapping of the future state was set up and the recommendations of the Lean tools that best contribute to the reduction of waste in the company were located, with a potential reduction of 70% in the setup in the lithography sector and 50% in the stamping and assembly sector, a potential 10% increase in equipment availability, a potential reduction in jobs and also a potential reduction of approximately 32% in excess materials in stock, thus promoting a possible percentage reduction in the company's current Lead Time of 12.5%.
