【摘要】 本文综述了聚合物注射成型保压分析的理论模型及其描述方程，并对今后的发展方向进行了展望。保压过程是一个非等温过程，熔体具有可压缩性，弹性的影响不应忽略．对于结晶聚合物，应考虑结晶对压力分布和温度分布的影响。更多还原

【Abstract】 The hierarchy of mathematical models of the packing phase in injection molding is reviewed. Several different models leading to the formulation of the governing equations are discussed. Compressibility, non-isotherm, viscoelasticity and crystallization must be considered in packing analysis. Further research includes 3D simulation and prediction of the microstructure of macromolecules.更多还原
