In general, the rein-forced composite with fibers are used in the plastic processing, and the major aim is to increase the parts strength. In this study, the authors try to utilize the mold flow analysis with Taguchi method to complete the effects analysis of flowing balancing and parts warpage considering the different fiber contents in the H-type runner system. In the flow balancing analysis, the injection molding simulations are used to analyze the shear effects of the different fiber contents, and the results show the compound viscosity increasing with the fiber content increasing. The increased viscosity will lead to reduce the balanced performances, and the molding compound without fiber presents the best balancing performance. In the warpage analysis, the Taguchi method with injection molding simulation is used to analyze the deformations differences of the rein-forced parts in the different cavities. The results show the part deformation variation is decreasing with S/N increasing, and the increasing fiber content will decrease the warpage effect. The control factors with their importance about the improving part warpage in the injection molding processing are the fiber content, the filling time, the melt temperature, and the mold temperature in order. The optimal processing parameters can be used to process for improving the part warpage effectively. Chung-Ming Tan Chao-Ming Lin 譚仲明 林肇民 2013 學位論文 ; thesis 80 zh-TW |
