This study aims to analyze the structural performance of a fan blade and its injection molding mold prior to the manufacturing stage using a Computer-Aided Design (CAD) and Computer-Aided Engineering (CAE) simulation approach. The scope of the study includes three-dimensional modeling of the fan blade and injection mold, a mesh study to obtain convergent simulation results, and mechanical response analysis under torsional and compressive loading conditions. Finite Element Analysis (FEA) was performed using SolidWorks Simulation with variations of fan blade materials, namely ABS, PA Type 6, and PEEK, as well as mold materials consisting of cast alloy steel, cast carbon steel, and cast stainless steel. The simulation results indicate that a mesh size of 6 mm provides stable von Mises stress values with an average error of 0.05%. An increase in applied torque on the fan blade results in a linear increase in stress and displacement, where PEEK exhibits the best structural stability with the smallest deformation. In the injection molding simulation, increasing compressive force leads to a linear increase in von Mises stress in both the cavity and core, with the maximum stress occurring in the core mold made of cast stainless steel. Furthermore, the simulation identifies several critical regions experiencing maximum stress, particularly in the fan blade shaft area.
