Simulation analysis of plastic injection based on Fluent

Plastic injection molding is a complicated physical process.The mathematical model of injection flowing and cooling process was established to verify the rationality of process parameters and predict the quality of product.By using the principle of CFD,plastic injection molding was simulated numerically to do the flow and thermal analysis by Fluent.Injection speed and melt temperature were well distributed.The product quality was very good.The applied process parameters were proved to be rational and suitable for actual engineering applications.
