Abstract(s)
A indústria automóvel sempre foi caracterizada por se manter na vanguarda do desenvolvimento de sistemas produtivos. Estes são definidos pela necessidade de suportar cadências de produção elevadas e constantes otimizações ao processo de fabrico. Visando a preservação da competitividade no mercado atual, deverão ser mitigados quaisquer fatores perturbadores da produção. É então responsabilidade da manutenção o controlo, conservação e reparação destes sistemas. O âmbito da presente dissertação foi apresentado pela empresa Fico Cables - Fábrica de Acessórios e Equipamentos Industriais, Lda, do grupo Ficosa Internacional S.A.. Foi definido como objetivo a redução do consumo das peças de desgaste que apresentassem o maior número de requisições. Adicionalmente, deverão ser implementadas ações de melhoria que impulsionem a redução do custo de aquisição e das condições gerais de trabalho, elevando a qualidade do processo produtivo. Posto isto, foi efetuado um estudo consolidando os dados obtidos, através do software, e a recolha de informação por intervenção e observação. Isto teve como objetivo efetuar a definição e caracterização técnica de todos os problemas que impulsionavam o consumo excessivo das peças de desgaste selecionadas. Foi desenvolvido o planeamento e efetuada a implementação bem como a consequente validação das ações de melhoria projetadas, com o intuito de mitigar todos os problemas encontrados. Os equipamentos em análise foram as MIZ (Máquina de Injeção de Zamak) e as LMEJ (Linha de Montagem de Elevadores de Janela), mais propriamente um de cada um dos seus subsistemas, o Subconjunto de Injeção de Zamak e o Dispositivo de Corte de Cabo. Estes são caracterizados pela injeção de terminais de Zamak na ponta de cabos e o corte mecânico de cabos de aço, respetivamente. Em suma, ambos os sistemas produtivos em estudo apresentaram resultados altamente positivos quer a nível financeiro quer a nível de qualidade do processo, disponibilidade dos equipamentos e de desenvolvimento produtivo.

These are defined by the need of sustaining high production cadency and constant optimizations of the manufacturing process. Aiming for the preservation of competitiveness within the current market, any disturbing factors of production must be appeased. Thus, maintenance is the activity to which the responsibility of control, preservation, and repair of said systems was attributed to. The subject of the present dissertation was presented by the company FicoCables – Fábrica de Acessórios e Equipamentos Industriais, Lda of the group Ficosa International S.A.. The goal was defined as the consumption reduction of the spare parts which presented the highest number of requests. Additionally, there must be implemented improvement actions that propel the reduction of the acquisition cost and the general conditions of work consequently raising the quality of the productive process. Therefore, a study was made consolidating the obtained data through software and the gathering of information by intervention and observation. The goal was to perform the definition and technical characterization of the problems that propelled the excessive consumption of the selected spare parts. A plan was developed, the implementation was executed, and the consequent validation of actions were projected, with the aim for the mitigation of all the problems found. The equipments in analysis were the MIZ (Máquinas de Injeção de Zamak) and the LMEJ (Linha de Montagem de Elevadores de Janela), more precisely one of each of their subsystems, the Zamak Injection, and the Subset of Cable Cutting Device. These are characterized by the Zamak injection on cable end and the mechanical cutting of cable, respectively. In conclusion, both productive systems in study presented highly positive results regarding the levels of process quality, equipment availability, financially and the productive development.
