The Multi-objective Optimization of Monitor Panel with Injection Molding Process Based on the GA and MPI
LIN Quan
Abstract：Welding marks ,w arping ,and shrinkage are the most common defects appearing in the injection molding process ,of which the welding marks become the most difficult problem to tackle . With the monitor panel as an example ,setting up multi‐objective function with the rate of the welding marks ,warping and shrinkage as an index through simulation analysis on selection toward program of different injection molding with the application of moldflow analysis software MPI and combination of the genetic algorithm GA as the overall searching tool is to undertake optimization design to the injection mold geometric parameters for the monitor panel .The research results show that the method is not only able to obtain the most proper welding location and length ,but also better the amount of warping and the rate of shrinkage effectively .
