For an HDPE Pipe Production Operator (Extrusion Line Operator), the main roles and responsibilities :
1. Machine Operation
Operate HDPE pipe extrusion machine as per production plan.
Start, stop, and monitor extrusion line safely.
Set and adjust machine parameters:
Extruder temperature zones
Screw speed (RPM)
Line speed
Vacuum calibration tank settings
Cooling water flow
Haul-off speed
Cutter/Coiler settings
Ensure stable production without interruptions.
2. Raw Material Handling
Check availability and correct grade of raw material (e.g., PE100).
Verify material batch/lot number before production.
Ensure proper mixing of resin, masterbatch, and additives (if applicable).
Prevent contamination of raw material.
3. Quality Control
Check pipe dimensions during production:
Outside diameter (OD)
Wall thickness
Ovality
Length
Appearance
Monitor:
Surface defects
Color uniformity
Black/stripe quality
Smoothness
Record inspection results in production and quality sheets.
Inform supervisor/QC about any non-conformity.
4. Production Monitoring
Maintain required production output.
Monitor pipe continuously during extrusion.
Avoid production losses and material wastage.
Ensure correct marking/printing on pipe.
Maintain proper coil/reel winding (for PE coils).
5. Troubleshooting
Identify basic machine problems:
Melt fluctuation
Pressure variation
Pipe size variation
Vacuum problems
Cooling issues
Surface defects
Report mechanical/electrical problems to maintenance team.
6. Safety Responsibility
Follow company safety rules and PPE requirements.
Operate machine safely.
Keep hands away from moving parts.
Follow lockout/tagout procedures during maintenance.
Report unsafe conditions.
7. Housekeeping
Maintain clean working area around extrusion line.
Remove scrap material properly.
Keep tools and gauges in proper condition.
8. Documentation
Maintain:
Production report
Machine parameter record
Raw material consumption record
Downtime report
Scrap/waste report
Quality inspection records
9. Team Coordination
Coordinate with:
Production Supervisor
QC Inspector
Maintenance Team
Packing/Dispatch Team
Support shift handover with complete information.
10. Key KPI for HDPE Pipe Operator:
Production output (kg/hour or meters)
Scrap percentage
Quality rejection rate
Machine downtime
Compliance with safety procedures
Correct documentation
