EFFECTS OF PROCESSING CONDITIONS ON PART MOLDABILITY OF IN MOLD DECORATION NYLON6 NANOCOMPOSITES MOLDING

摘要

In mold decoration (IMD) has attracted attention for industrial applications in recent years. In this paper, PC films with thickness of 0.125 mm and 0.175 mm combined varied ink formulas were be utilized and the effects of processing conditions on Nylon6 nanocomposites and Nylon6 molding were investigated. Related processing conditions include melt temperature, mold temperature, injection speed and packing pressure.It was found that high injection speed would increase shear stress leading to large printed ink will be washed out whereas high melt temperature would decrease shear stress. In addition, Nylon6 nanocomposites can reduce 50% washout region than the IMD Nylon6 molding.
