EFFECT OF CORE-SKIN VISCOSITY RATIO ON THE FORMATION OF LAYER INTERFACE AND MOVING MELT FRONTS DURING MOLDING FILLING OF CO-INJECTION

College of Environment Science and Engineering, Nanchang University, Nanchang 330029, China

摘要: 建立了共注成型充模流动的有限元模型，并利用Matlab与Visual C⁺⁺6.0混合编程技术开发了模拟软件，利用该软件对芯壳层熔体的粘度与芯壳层界面和移动前沿形貌之间的关系进行了数值模拟，并提出了确定关键成型工艺参数的指导原则。模拟研究结果与一些文献的实验结果相吻合。

Abstract: A finite-element model is established for the mold filling of co-injection, and a software package of numerical simulation was developed by means of Matlab and Visual C⁺⁺6.0. The numerical simulation of the relation was implemented between the core-skin-viscosity ratio and the formations of layer interface and moving melt fronts, and then a set of principles to guide the selection of the key molding parameters was put forward. The result of case study of numerical simulation is in good agreement with the experimental result given in some literature.
