    Aplicações de simulações computacionais para melhorias e redução de custos no processo de injeção de termoplásticos
    (2021-07-14) Ribeiro, Rayanne do Nascimento Guerra Melo; Figueiredo, José Fernando Dagnone
    The present project is intended to study the importance using computer simulations with the Inventor Moldflow 2019 software to study the main defects and the possibility of cost reduction in the thermoplastic injection process as a benefit of using industry 4.0 concepts. For this, thermoplastics High Density Polyethylene (HDPE or HDPE) and Polypropylene (PP) were studied to simulate the injection process of the plastic component of the domestic orange juice cone. The results induced that the injection parameters are influenced by the morphological properties of the polymers, with the crystallinity being directly induced in the contraction and injection pressure of thermoplastics. So, it was possible to show the potential of computer simulations as a tool for cost reduction in the thermoplastic injection process.

    Aumento da produtividade através da aplicação da metodologia World Class Manufacturing (WCM) com foco no pilar Workplace Organization (WO) em uma linha de montagem do setor automotivo de Pernambuco
    (2020-11-04) Costa, Laís Martins Correia da; Figueiredo, José Fernando Dagnone; http://lattes.cnpq.br/0648307320706020; http://lattes.cnpq.br/5181183753810801
    The Word Class Manufacturing (WCM) emerges as an efficient and effective management model, based on the concepts of zero waste, zero breaks, zero defects and zero stock, ensuring the safety of all employees, quality in all parts and high performance production. The main objective of this work was to show how to increase the productivity of a production line of the Industry of the automotive sector of Pernambuco with a focus on the application of the reactive and preventive concepts and tools of the pillar, Workplace Organization (Organization of the Workplace - WO), through the implementation of Kaizens referring to steps (steps) 1,2,3,4 and 5. The results obtained reveal that the objective was achieved and that the expansion of activities to similar production lines is possible, proving the efficiency of the method
