Twin Screw Extruder Operator

1.    Raw Material Preparation: Check polymer, pigment, additives, filler and other raw materials according to the production recipe.

2.    Weighing: Weigh all raw materials accurately as per the batch formulation.

3.    Material Mixing: Mix the raw materials properly to achieve uniform distribution before feeding into the extruder.

4.    Machine Inspection: Check the twin screw extruder, feeder, die, cooling system, pelletizer and other machine parts before starting production.

5.    Temperature Setting: Set the barrel temperature zones according to the polymer and Masterbatch grade.

6.    Feeding: Start the feeder and maintain the required feeding rate according to the production requirement.

7.    Extruder Operation: Operate the twin screw extruder and maintain the required screw RPM, feed rate and process conditions.

8.    Compounding: Ensure proper melting, mixing and dispersion of pigment, additives and other materials inside the extruder.

9.    Process Monitoring: Continuously monitor temperature, melt pressure, motor load, torque, screw RPM and feeder speed during production.

10. Strand Cooling: Check the extruded strands and ensure proper cooling through the water bath.
