Abstract

Metal injection molding feedstocks are typically highly filled thermoplastic systems. In this study, the effects of feedstock composition on flow properties are examined using the capillary rheometer and the extrusion plastometer. The two techniques are also compared with respect to sensitivity to feedstock composition and their utility in predicting variations in processing performance.
