STUDY ON THE BREAKTHROUGH OF THE CORE MELT FRONT FOR THE CO-INJECTION MOLDING

Zhong Xuguang, Sun Mao, Zhang Xiaoxun, Liu Hesheng, Zhou Guofa (College of Environmental & Chemical Engineering, Nanchang University, Nanchang 330029, China)  
The melt front breakthrough of the core is the main cause of forming waster in the co-injection molding. The initiating mechanism of the front breakthrough is lack of understanding, therefore, the experimental study and numerical simulation on the effect of the polymer rheological parameters and process parameters on the melt front breakthrough of the core are implemented. The relation between each parameters and the front breakthrough is established. And the initiating mechanism of the melt front breakthrough is disclosed in the opinion of the rheologieal theory.
