EFFECT OF FLOW BEHAVIOR ON INTERNAL STRUCTURE OF PC/ABS INJECTION MOLDINGS

摘要

Effect of flow behavior on internal structure of PC/ABS injection moldings was investigated. The cross sections in flow direction of etched specimens were observed, and the thicknesses of the cavities (ABS rich region) through thickness direction were measured. •Subsequently, the flow field was calculated by using CAE software and the relationship between the flow behavior and internal structure was examined. As a result, it was found that the maximum shear stress and solidification time of the resin was important in determining the final morphological properties.
