Özet

This paper investigated the pressure drop during the extrusion processes. The objectives of this investigation were to increase efficiency of plastic extrusion which plastic equipment produced. In the experimental processes, two rectangular dies were used. HD 7255 thermoplastic was used as the fluid material of extrusion. A difference occurred between inlet and outlet. This difference was 2.34 MPa in terms of the pressure drop and was 0.001216 (kg s -1 ) in terms of the flow rate. The results of power law model is found in good agreement with experimental results for outlet sections of process.
