Due to their high efficiency, pressure invariance, and managed throughput and melt temperatures, groove feed systems are becoming accepted pertaining to the extrusion of pipes widely, blown films, and blow molded content articles. Within the research offered in this paper, a completely instrumented 45 mm extruder equipped with a grooved fed bushing was utilized to measure pressure distributions, screw and die features, and melt heat profiles. The screw geometry included compression and decompression zones, and Saxton distributive and Maillefer dispersive mxing heads. The screw and die characteristic curves show the high system efficiency where throughputs comparable to 60 and 90 mm regular extruders had been measured. The huge throughput induced a dramatic decrease in melt heat range measured at the tip. To better plastic recycling machines understand and verify our experimental results, analytical types were used.
