Abstract Axial fans are usually manufactured by injection molding method. Common injection defects such as warpage and deformation affect the ma-nufacturing accuracy of the axial fans, and result in changes in fan blade structure, which exerts impacts on the performance of power, noise and dynamic balance. Taking a straight airfoil axial flow fan as the research target, polybutylene terephthalate (PBT) material as the injection raw materials for process simulation, Taguchi experiment was used to analyze the influence of process parameters on warpage. The results demonstrate that mold surface temperature, melt temperature, injection time and holding pressure were the main influencing factors. The optimal process combination was determined by response surface methodology (RSM). The maximum Z-direction warpage was decreased from 0.197 0 mm to 0.108 1 mm, while the average warpage in Z-direction was decreased from 0.104 0 mm to 0.035 9 mm, with the optimization value of 0.088 9 mm and 0.068 1 mm, respectively.
