Non-monotonic shrinkage behavior of a highly filled polymer-metal feedstock during injection molding and its relation to binder phase transitions
Highly filled polymer–metal feedstocks exhibit complex thermophysical behavior because of their high solid loading and multicomponent binder systems. In this study, the green-part shrinkage of a 17-4PH MIM feedstock containing approximately 92 wt% metal powder was investigated as a function of mold temperature, packi...
