Using multi-objective evolutionary algorithms for optimization of the cooling s...
Fernandes, Célio; Pontes, A. J.; Viana, J. C.; Gaspar-Cunha, A.The cooling process in polymer injection moulding is of great importance as it has a direct impact on both productivity and product quality. In this paper a Multi-objective Optimization Genetic Algorithm, denoted as Reduced Pareto Set Genetic Algorithm with Elitism (RPSGAe), was applied to optimize both the position and the layout of the cooling channels in the injection moulding process. The optimization model...

Fernandes, Célio; Pontes, A. J.; Viana, J. C.; Gaspar-Cunha, A.A Multi-objective optimization methodology has been applied in the optimization of polymer injection molding process. This allowed the optimization of the operating conditions of the process from mold flow simulations, taking into consideration the existence of 5 criteria simultaneously, such as temperature dif-ference on the molding at the end of filling, the maximum pressure, the pressure work, the volumetric...
Métodos espectrais aplicados ao filme de fundido de um processo de extrusão de ...
Gama, Sílvio M.A.; Fernandes, Célio; Gaspar-Cunha, A.De entre os processos de transformação de polímeros destaca-se a moldação por extrusão. A moldação por extrusão consiste em criar uma forma para um determinado material (por exemplo, um polímero), forçando-o a passar por um canal. Este trabalho incide, inicialmente, na descrição do processo de plasticização em extrus ão, tendo em vista a sua modelação matemática. Em particular, apresentamos o modelo matemático ...
Setting of the operative processing window in injection moulding using a multi-...
Fernandes, Célio; Viana, J. C.; Pontes, A. J.; Gaspar-Cunha, A.The use of commercially available injection moulding simulation software’s allows us to predict the process response to the operating conditions defined. These codes can be used to define better injection conditions to use in specific situations, i.e., to optimize the process. Generally, this is an iterative procedure requiring the analysis of multiple outputs (pressures, temperatures, shear stresses profiles) ...
