Abstract

Screw-freezing experiments in a single-screw extruder were conducted with screws having different compression ratios and compression rates for an ABS resin. Three-dimensional finite element simulations of the melting process in the compression section of the extruder were also performed for the compression ratios and compression rates used in the experiments. Even though some discrepancies existed between the numerical predictions and experimental data, the melting profiles predicted by the finite element simulations were in good agreement with the corresponding experimental data.
