Abstract

The objective of this work is to elucidate the rheological behavior and then to optimize the properties of plastisols loaded with 316L water- and gas-atomized powders, as feedstock of Metal Injection Molding (MIM) process.<BR>The results obtained were summarized as follows:<BR>(1) Judging from powder/binder mixing torque, mixture viscosity is greatly influenced by powder characteristics (shape, size) and generally, related to its tap density.<BR>(2) Practically, water-atomized powder (irregular) needs thermoplastic binder approximately 2.5wt% more than gas-atomized one (spherical) to prepare the optimal feedstock.<BR>(3) Powder plastisols show Bingham-type flow behavior and consequently, give almost the same viscosity-shear rate relationship all over the powders for the optimal solids loading (Φ_o).
