| In this study, the net-shape injection molding of steatite for the most appropriate rheology, debinding and molding parameters were determined. The investigations of the rheology as four different feedstock of melt flow index (554 - 988 g/10 min), flow behavior index (0.507 - 0.601), fluency (5.21 - 8.99 × 10 -3Pa -1s -1) and activation energy values (26,9 - 39,1 kJ/mol) were ideally determined using by capillary and torque rheometer machine. The steatite + polyethyleneglycol (PEG) + polypropylene (PP) + stearik asit (SA) have most ideally mixture for rheology. This feedstock for molding was occured at different flow rate (15-25 cm 3), cylinder temperature (185-200°C) and injection pressure (1000-1350 bar) values. The debinding processes carrided out at two steps as solvent and thermal debinding. The thermal debinding carried 10 °C/min and 1°C/min for heating rate. The samples were investigated to determine of distortion, cracks and deformation in the inner parts with SEM machine. The net-shaped samples were obtained at optimum rheology, debinding and molding parameters. |
