The aim of the present work was to evaluate process parameters influencing the dimensional variation of AISI 316L MIM components during manufacturing. 3D Finite Element (FE) models were used to reproduce thermal and mechanical stress/strain fields during molding of MIM components. In addition, experimental plans were used to reinforce outcomes of numerical simulations. The developed models predicted the thermal history of the injection molding process phase and temperature distributions for any position in the component. This research confirmed that FE simulations were an efficient method to assess the influence of process parameter variation on component manufacturability, suggesting adjustments to improve its quality. The use of the FE models allowed the process efficiency to be improved, as well as MIM component quality.

Abstract
The aim of the present work was to evaluate process parameters influencing the dimensional variation of AISI 316L MIM components during manufacturing. 3D Finite Element (FE) models were used to reproduce thermal and mechanical stress/strain fields during molding of MIM components. In addition, experimental plans were used to reinforce outcomes of numerical simulations. The developed models predicted the thermal history of the injection molding process phase and temperature distributions for any position in the component. This research confirmed that FE simulations were an efficient method to assess the influence of process parameter variation on component manufacturability, suggesting adjustments to improve its quality. The use of the FE models allowed the process efficiency to be improved, as well as MIM component quality.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
