This work follows the general framework of polymer injection moulding simulation whose objectives are the mastering of the injection moulding process. The models of numerical simulation make it possible to predict the propagation of the molten polymer during the filling phase from the positioning of one point of injection or more. The objective of this paper is to propose a particular way to optimize the geometry of mold cavity in accordance with physical laws. A direct correlation is pointed out between geometric parameters issued from skeleton transformation and Hausdorff's distance and results provided by implementation of a classical model based on the Hele-Shaw equations which are currently used in the main computer codes of polymer injection.

Feasibility studies about processing lignocellulosic reinforced polymer composites by injection moulding have been receiving widespread attention nowadays. The aim of this research was to identify the optimal selection of parameters, significant parameters, and effects of the injection-moulding parameters during the post filling-stage. In this simulation study, the modelling of an automotive component, namely the Proton Waja CAMPRO car engine cover, required a 3-D model and mesh generation to obtain the mouldability of its composite material using the injection moulding process. Autodesk Moldflow Insight® was used to simulate and analyse the injection-moulding process. Therefore, 60 wt% of wood filler reinforced polypropylene was evaluated under optimised injection parameters (injection temperature, mould temperature, injection pressure and flow rate) during the post-filling stage simulation (filling time, average velocity, volumetric shrinkage, sink marks, and shear stress). In addition, numerical simulation by the Taguchi method consisting of S/N ratio and ANOVA were used in this research to determine which significant factors would affect all responses. Based on the numerical simulation results, the flow rate shows the most significant parameter for the reduction of filling time, volumetric shrinkage, sink marks, and shear stress while also enhancing the average velocity on the car engine cover.
