Abstract(s)
Atualmente, muitas organizações, principalmente as do setor automóvel, enfrentam dificuldades nos novos mercados competitivos e direcionados para o cliente, onde os prazos de entrega são cada vez mais curtos e a procura pela flexibilidade de produção é cada vez maior. Neste contexto, o paradigma Lean manufacturing e o conjunto de ferramentas a ele associado, tornam-se extremamente necessários, na constante procura pela melhoria contínua. O presente projeto objetiva melhorar o processo produtivo de construção de pneus agrícolas, na Continental Mabor, através da implementação de conceitos e ferramentas inerentes ao Lean manufacturing, em particular o SMED (Single Minute Exchange of Die). A primeira fase deste projeto consistiu num levantamento e análise detalhada do processo produtivo da construção de pneus agrícolas e dos tempos e métodos utilizados na realização dos setups associados aos equipamentos utilizados em fases especificas deste processo. Posteriormente, numa segunda fase, objetivando a diminuição dos tempos de setup, foram identificados os problemas existentes na fase de construção de pneus agrícolas e as respetivas oportunidades de melhoria, usando as ferramentas do Lean manufacturing, nomeadamente o SMED e o 5S. A fase seguinte, consistiu na implementação destas melhorias e na análise dos resultados obtidos. Finalmente, foi possível constatar que as implementações efetuadas refletiram-se, como esperado, na efetiva redução dos tempos dos setups levados a cabo nos módulos de construção. Os resultados da implementação da metodologia SMED, permitiram reduções da duração dos setups entre os 2% e os 43%. Sendo que, estes resultados, representam o primeiro passo para o aumento da flexibilidade da empresa e da possibilidade de produção em pequenos lotes.
Nowadays, many organizations, mainly those in the automobile sector, face difficulties in new competitive and customer-oriented markets, where delivery times are getting shorter and demand for production flexibility is increasing. In this context, the Lean manufacturing paradigm and the set of tools associated with it, become extremely necessary, in the constant search for continuous improvement. This project aims to improve the productive process of construction of agricultural tires, at Continental Mabor, through the implementation of Lean manufacturing concepts and tools, in particular, the SMED (Single Minute Exchange of Die). The first phase of this project consisted of a survey and detailed analysis of the production process of the construction of agricultural tires and of the times and methods used in carrying out the setups associated with the equipment used in specific stages of this process. Subsequently, in a second phase, aiming at reducing setup times, the existing problems in the construction phase of agricultural tire modules and the respective improvement opportunities were identified, using Lean manufacturing tools, namely SMED and 5S. The next phase consisted of implementing these improvements and analyzing the results obtained. Finally, it was possible to verify that the implementations were reflected, as expected, in the effective reduction of the setup times carried out in the construction modules. The results of the implementation of the SMED methodology, allowed reductions in the duration of the setups between 2% and 43%. These results represent the first step towards increasing the company's flexibility and the possibility of small lots production.
