AN EXPERIMENTAL INVESTIGATION INTO SOLIDS FEEDING CHARACTERISTICS OF A SINGLE PIECE BARREL WITH INTEGRAL FEEDPORT DESIGN VS A STANDARD TWO PIECE WATER COOLED FEEDBLOCK AND BARREL CONFIGURATION

摘要

Differences in solids conveying, screw pressure profile generation, output and melt temperature varies between single piece barrel with integral feedport design and two piece water cooled feedblock and barrel designs. Two different resins will be studied using the same screw design for each barrel configuration.
