| Abstract: | The Moldflow software has been used to analyze the molding process of a 2-cavity hot runner injection mould for PET/PEN bottle-blank.The mold filling,flowing and cooling processes were visually simulated.It is to predict the potential defects of plastic parts in the forming process so as to optimize the cooling channels′ diameter,layout and the size of gating system,then to propose an optimization injection scheme.By feasibility simulation,the results help to solve the injection product design,mold design and defects in the molding process.This designing method can shorten mold manufacture period,lower costs and improve the production efficiency with accuracy,convenience and efficiency. |
