HDPE PIPE EXTRUSION PROCESS & LINE TROUBLESHOOTING
- Lead specialised, hands-on troubleshooting of HDPE pipe extrusion lines, including extruders, extrusion heads/dies, vacuum sizing tanks, cooling systems, haul-off units, cutters and other downstream equipment.-Diagnose and resolve complex extrusion defects including wall-thickness variation, outside-diameter instability, ovality, surface roughness, melt fracture, sagging, shrink-back, internal stress and dimensional inconsistency.- Establish, adjust and optimise extrusion process windows based on HDPE resin grade, pipe diameter, SDR classification and required production output.- Calibrate critical process parameters including barrel and die temperature zones, screw speed, melt temperature, melt pressure, extrusion output, vacuum level, cooling-water temperature/flow and haul-off speed.- Troubleshoot interactions between extrusion output, die tooling, vacuum sizing, cooling and haul-off speed to achieve stable pipe dimensions and consistent production.
