Operate and control twin-screw compounding extruders, high-speed mixers, vacuum loading systems, and
strand/die-face pelletizers.
Accurately set and monitor critical process parameters: barrel zone temperatures, screw RPM, feeder dosing
speeds, melt pressure, and vacuum levels.
Ensure accurate raw material feeding (PVC/CPVC resin, heat stabilizers, impact modifiers, processing aids,
lubricants, and color pigments) per batch recipes.
Inspect output pellets for uniform size, bulk density, moisture content, porosity, and color consistency.
Perform regular machine changeovers, screen pack changes, die head cleaning, and pelletizer blade
adjustments.
Execute routine lubrication, preventive cleaning, and report mechanical/electrical irregularities immediately to
maintenance.
