- Abstract:
-
In the process of injection molding, the non-uniform filling speed of the melt front will lead to inconsistent orientation and non-uniform shrinkage and warpage deformation, and the ideal filling mode should keep the MFV unchanged as much as possible during the filling process. The key to controlling MFV is to optimize the injection flow rate of the mold filling process. In order to solve this problem, the genetic algorithm and numerical simulation technology are combined for the optimization of the injection molding filling process, and the optimal control point in the screw stroke and the optimal value of the injection volume flow rate at the control point are determined to obtain uniform and consistent MFV.
