Num mercado cada vez mais competitivo e industrializado, é essencial que as empresas se mentalizem que o caminho a seguir deve passar pela aposta da otimização dos seus processos produtivos, diminuição de custos e aumento da qualidade de produtos. Torna-se necessário adotar modelos de gestão inovadores, capazes de fornecer aumento de produtividade com redução de custos, como o caso da filosofia Lean. A indústria metalomecânica está integrada num dos mercados mais competitivos que existem em Portugal. Perante esse cenário, torna-se vital reduzir os desperdícios associados aos processos produtivos em todos os sectores recorrendo aos princípios e práticas Lean, como o caso da metodologia SMED. Este trabalho reflete um projeto de implementação da metodologia SMED numa empresa de perfilagem a frio, bem como efetua um estudo dos conceitos associados à metodologia e pretende demonstrar todas as vantagens associadas à sua utilização, como forma de redução de desperdícios. Devido a algumas dificuldades na introdução das ações de melhoria, os resultados obtidos não alcançaram valores satisfatórios. Seria indispensável uma janela de tempo maior para melhorar a assimilação e enraizamento destes processos. No entanto, este trabalho servirá como ponto de partida para desenvolver melhorias futuras, dando ênfase a todo o processo produtivo, visando a otimização de processos e metodologias. Neste trabalho, com aplicação de 5S obteve-se uma melhor organização e limpeza, com aplicação do SMED houve uma melhoria de 5 min na passagem de atividades externas para internas, com mudança de layout houve uma otimização de 40% nos tempos de deslocação para alimentação de matéria-prima aos equipamentos e ainda uma melhoria de 30’’ sao unir a matéria-prima antes de entrar no equipamento.
In a more and more competitive and industrialized market, it is essential that companies realize that the way forward must pass through optimizing their production processes, reducing the costs and increasing product quality. Nowadays it’s necessary to adopt innovative management models that can provide increased productivity at minimal cost, such as the Lean thinking. The metalworking industry is integrated in one of the most competitive existing markets in Portugal. Given this it’s fundamental to reduce the waste in all sectors of the production process, using the good Lean principles and practices, such as the SMED methodology. This paper shows a project of implement the SMED methodology in a company of the cold profiling, as well as carries out a study of the concepts associated with the methodology and aims to demonstrate all the advantages of its use around a way of reducing waste. Due to some difficulties in the introduction of the improvement actions, the results were not satisfactory. Would be essential a larger time window to improve the assimilation and entrenchment of these processes. Despite of these results, this work will be a starting point for future improvement develops, embracing all production process to achieve processes and methodologies optimization. In this work, with 5S application, a better organization and cleaning was obtained, with application of SMED there was a 5 min improvement in the transition from external to internal activities, with layout change there was a 40% optimization in the travel times for feed of raw material to the equipment and even a 30’’ improvement in joining the feedstock before entering the equipment.
