The sandwich injection molding technique can be used in a wide range of engineering applications. In this study, the development of core materials and the break through phenomenon in sandwich injection molding were investigated. The samples were preferred using a bar-flow mold. The dependence on the viscosity and the injection speed of skin/core materials were studied. It was noted that the core material tends not to completely penetrate through the skin material the "break through" phenomenon. It is considered that the break through phenomenon depends on the melt strength of the freezing skin layer at the flow front.
