Effect of Particle Size and Shape on Wall Slip of Highly Filled Powder Feedstocks for Powder Injection Molding
Original language description
Highly filled materials which are increasingly used in technologies such as powder injection molding or additive manufacturing material extrusion bring many advantages in comparison to traditional ones due to the better processability and higher mechanical properties. The rheological characterization is one of the possibilities how to determine instabilities in these materials during shearing and optimize materials processing. Therefore, the study focuses on the effect of size and shape of used powder particles as one of the main factors that affected the wall-slip which is a typical phenomenon determining the flow performance of highly filled materials. Regular and coarse stainless steel powders were used for the preparation of highly filled feedstocks containing polyethylene based binder system. Mooney rheological analysis was performed on two types of capillary dies (flat and conical) using a capillary rheometer. The wall-slip effect, as seen in this analysis, appears to vary significantly with differences in size, shape, and entrance angle of the used capillary.
