Com a crescente competitividade na indústria, é inevitável que as empresas tomem medidas, para que todos os seus colaboradores eliminem, de forma continua, os desperdícios e criem mais valor. Neste sentido, este projeto teve como base o estágio realizado na SF Moldes S.A. / Schneider Form Portugal, empresa que concebe, desenvolve e fabrica moldes em aço, tendo em vista o processo de moldação por injeção de plástico, que tem como destino principal, o setor automóvel. O intuito foi implementar o pensamento Lean em todos os setores e pessoas envolvidas, atingindo os seguintes objetivos: i) uniformizar a modelação de standards no Departamento de Projeto de Moldes; ii) criar metodologia para o dimensionamento de aços; iii) organizar a produção; iv) elaborar de documentos de apoio à produção; v) uniformizar o stock de grafite e vi) criar ferramentas de apoio à manutenção. Finda a análise aos processos existentes, foram identificados problemas e propostas de soluções para os resolver. Assim, foram propostas as seguintes melhorias: i) criação de base de dados; ii) aplicação do Método de Elementos Finitos; iii) aplicação da ferramenta 5S; iv) elaboração de documentos de apoio; v) regulação de stock através de kanbans e vi) fase de implementação da Manutenção Centrada na Fiabilidade, utilizando a ferramenta Failure Mode and Effects Analysis. Após a implementação das propostas supramencionadas, foi possível a redução do tempo na modelação de componentes e no molde final, minimizando também os erros de modelação. Houve uma poupança na compra de aços e foi implementada uma produção organizada com uma melhoria nas auditorias de 35% para 85%. Houve um aumento da produtividade, mais autonomia e comunicação entre setores, regularização de stocks e diminuição de manutenção corretiva.
With the growing trend in the industry, it is inevitable that companies act, so that all their employees continuously eliminate waste and create more value. In this sense, this project was based on the internship carried out at SF Moldes SA / Schneider Form Portugal, a company that designs, develops and manufactures steel molds, in view of the plastic injection molding process, which has as its main destination the automotive sector. The aim was to implement Lean thinking in all sectors and people involved, achieving the following objectives: i) standardize the modeling of standards in Mould Design Department; ii) create a methodology for dimensioning steel; iii) organize production; iv) preparing production support documents; v) standardize the graphite stock and vi) create tools to support maintenance. After analyzing the existing processes, problems were identified and proposals for solutions to solve them were identified. Thus, the following improvements were proposed: i) creation of a database; ii) Application of the Finite Element Method; iii) Application of the 5S method; iv) elaboration of supporting documents; v) tock regulation through kanbans and vi) implementation phase of Reliability Centered Maintenance, using the Failure Mode and Effects Analysis tool. After the implementation of the proposals, it was possible to reduce the time in component modeling and in the final mold, also minimizing modeling errors. There was a saving in the purchase of steel and organized production was implemented with an improvement from 35% to 85% in the auditing. There was an increase in productivity, more autonomy and communication between sectors, regularization of stocks and a decrease in corrective maintenance.
