ABSTRACT

After the extrusion process the remaining of polymers in the extruders cause some problems like degradation and impurity in process, therefore after each batch the extruder should be cleaned. Using self-wipe twin-screw extruder is a method, to solve this problem. Production of self-wipe screw modules is very difficult, time consuming and is not economical. In this research, we have presented a novel, quick and economical method for producing self-wipe modules with desirable profiles.
