摘要

The object of this experiment is to investigate the effects of gate design, shear history, processing conditions, and melt rotation on gate blush and tiger striping. The part being molded and examined is a .101 meter impact disk. The parts were measured using a visual measurement system based on the quality of the surface finish. The materials in question are TPE, PC/PET blend, PC/ABS blend, and Acetal. Shear history increases gate blush on molded parts. Injection velocity alters tiger striping while a low melt temperature eliminated tiger stripes on the part.
