This paper is committed to analyze the effects of the material parameters and molding process parameters of co-injection on the layer thickness distribution.The emphasis is placed on the effect of the interaction between viscous encapsulation and interfacial instability on the layer thickness distribution.It is proposed that a three-dimensional viscoelastic model is the only way of predicting such an interaction precisely.
