In the research, Taguchi method is employed to observe how the key process parameters, mold temperature, injection speed, packing pressure, packing time and cooling time affect the replication ability of micro-structure. Further, we intend to resolve the warping condition of light guided plates, and improve their brightness and uniformity with injection compression molding method. A 17” large-sized light guided plate with V-groove micro-structure has been selected as a research vehicle to evaluate the performance of injection compression molding coped with L18 Taguchi experimental design method. The experimental results show that the higher the mold temperature is, the higher the replication ability of light guide plates’ micro-structure will be. Comparing to conventional injection molding method, it shows that the replication height of V-groove raises from 78.25% to 82.38%. The corresponding yield rate is estimated to significantly improve from 43.29% to 99.6%. |
