摘　　要：基于Hele -Shaw模型 ,采用CAE技术 ,模拟了顺序共注成型中几个重要工艺参数———温度、壳层预填充量、注射速度等对其成型过程的影响。并用流变学理论进行分析 。On the basis of general Hele-Shaw model,the simulation of the effect of several important molding process parameters on sequential co-injection molding process was implemented by means of CAE technique which involves temperature,prefilled polymer volume fraction and injection velocity.And the mechanism of the effect of those molding process parameters on the sequential co-injection molding process was disclosed in the opinion of rheological theory.

关 键 词：塑料加工 工艺参数 顺序共注成型 数值模拟 影响机理
