Temperature Dependent Flow Properties of Powder Injection Moulding Compounds
Original language description
The temperature dependent flow properties of highly filled polymer compounds intended for production of hard metal parts by injection moulding (PIM) technology were studied.The pure binder based on polyethylene, ethylene and butyl acrylate block copolymer and paraffin, and its compounds with hard metal carbide powder (up to 55 vol. %) were prepared by melt mixing. The Arrhenius relation for these materials is valid only in the stable flow region. At the temperature above 170°C the compounds filled with45 vol. % carbide powder and higher exhibit an unstable flow of pressure oscillation type. The onset of the oscillations is strongly affected by temperature. The relation between critical shear stress of the onset of pressure oscillations and temperatureis non-linear.
