Abstract EN
The impact of binders and temperature on the rheological properties of feedstocks used in low-pressure powder injection molding was investigated.
Experiments were conducted on different feedstock formulations obtained by mixing Inconel 718 powder with wax-based binder systems.
The shear rate sensitivity index and the activation energy were used to study the degree of dependence of shear rate and temperature on the viscosity of the feedstocks.
The injection performance of feedstocks was then evaluated using an analytical moldability model.
The results indicated that the viscosity profiles of feedstocks depend significantly on the binder constituents, and the secondary binder constituents play an important role in the rheological behavior (pseudoplastic or near-Newtonian) exhibited by the feedstock formulations.
Viscosity values as low as 0.06 to 2.9 Pa·s were measured at high shear rates and high temperatures.
The results indicate that a feedstock containing a surfactant agent exhibits the best moldability characteristics.
