Abstract: The rheological behaviors of feedstocks for powder extrusion molding, in the temperature range of 40~ 80℃and the Newton shear rate.γof 3~800 s^-1, were studied. The effects of feedstock constitution, shear rate and temperature on apparent viscosity, shear stress and active energy were investigated. The viscose-flow active energy of PEM feedstocks is 15.89~90.77 kJ/mol. Based on this research, the PEM technical parameters have optimized.
