Simulations of cycle-averaged mold surface temperature in mold-cooling process by boundary element method

Abstract In the present study, the mold-cooling process simulations are developed by using a modified boundary element technique. The mold surface temperature distribution is calculated on a cycle-averaged basis. The temperature distribution and the temperature profile of the polymer melt are then computed by finite difference method in a decoupled manner. Both the analyses represented by a middle-cavity-surface-boundary approximation and a full-cavity-gap-boundary approach are performed and compared. The sensitivity of the analysis results to the element aspect ratio is also studied.
