Comparison between Middle-face Model and 3D Model and Experiment of Gas-assisted Injection Molding

摘要

Based on the research about the injection molding simulation technology such as 2.5-d model and 3D model, Numerical analysis on a same gas-assisted product was implemented using Moldflow software's middle-face model and 3D model technology, and the physical experiment was also implemented. Through comparing the simulation results and experimental results, it shown that the time of the gas-assisted injection molding simulation based on 3D model is long, but the simulation results are more in line with experimental results than middle-face model. The numerical simulation using 3D model can truly and reliably predict the product's molding process, and meet the demand to guide production.
