Investigating the Impact of Process Parameters on Quality of Injection Molded Plastic Axial Fan Blades: A Moldflow Simulation Study

The injection molding process is widely used in the manufacturing of plastic components, including axial fan blades. To achieve optimal performance and quality, it is crucial to carefully select and optimize process parameters. In this study, a parametric investigation of the injection molding process for plastic axial fan blades was conducted using Moldflow simulation. SolidWorks software was utilized for part modeling, and the simulation results were analyzed to determine the impact of various process parameters on the final product’s quality. From the results, injection time affects shrinkage and warpage of material, as increasing injection time leads to unstable shrinkage and affects the speed of shrinkage cooling during the chilling process, resulting in warpage. Melt temperature also affects shrinkage and warpage. Increasing temperature creates space for defects, but if the temperature is too high, viscosity increases and the mold may not be filled in the set time. Based on these findings, recommendations for process parameter optimization were made to improve the overall quality of the plastic axial fan blade. The results of this study have important implications for the optimization of the injection molding process for various plastic components.
