| Outline of Final Research Achievements |
This research project has performed a multi-objective optimization of process parameters in plastic injection molding using conformal cooling channel, in which variable packing pressure profile was adopted for warpage reduction and variable injection velocity was adopted for weldline reduction. Numerical simulation in plastic injection molding is so intensive that sequential approximate optimization using computational intelligence is used to optimize the process parameters. The optimal process parameters were determined through the numerical simulation. The experiment was also carried out to examine the validity. Through numerical and experimental result, the validity of this research project has been confirmed.
