Abstract
In this study, with the glass fiber reinforced Polyoxymethylene composite material as the subject, we examined the impact of different injection molding process parameters such as melt temperature, mold temperature, packing pressure, injection speed and packing time on mechanical properties. We designed the experiment by using the orthogonal array of Taguchi method, and obtained the single quality characteristic optimization parameters by using the main effect analysis and variance analysis of Taguchi method. Based on the experimental quality data, we integrated principal component analysis and grey relation analysis to identify the combination of multiple quality characteristics optimal process parameters. As the research results suggest, if the four quality characteristics including tensile strength, hardness, impact strength and bending strength are considered, the optimal conditions are glass fiber content of 20 wt%, melt temperature 230 °C, mold temperature 60 °C, packing pressure 50 MPa, injection speed 60 mm/s and packing time 1.5 s. Finally, it was verified that the planned experiment of this study can effectively enhance the material’s multiple quality characteristics with good reproducibility.
