Effect of processing conditions on the shrinkage and warpage of glass fiber reinforced PP using microcellular injection molding
This study was aimed at understanding how the process conditions affected the dimensional stability of glass fiber reinforced PP by microcellular injection molding.A design of experiments (DOE) was performed and plane test specimens were produced for the shrinkage and warpage analysis.Injection molding trials were performed by systematically adjusting six process parameters (i.e.,Injection speed,Injection pressure,Shot temperature,SCF level,Mold temperature,and Cooling time).By analyzing the statistically significant main and two-factor interaction effects,the results showed that the supercritical fluid (SCF) level and the injection speed affected the shrinkage and warpage of microcellular injection molded parts the most.
