Frequently Asked Questions

Q1: Unstable extrusion output, fluctuating pipe diameter & wall thickness

Reasons: Blocked feeding system, uneven mixing of raw materials, worn screw/barrel, unstable main motor frequency. Solutions: Clean the feeder; check mixing formula; repair or replace worn screw; calibrate VFD parameters.

Q2: Poor plasticization, crystal dots & fish eyes on pipe surface

Reasons: Improper heating temperature, wet raw materials, mismatched screw speed, unmelted resin particles. Solutions: Dry raw materials fully; adjust barrel temperature curve; optimize screw rotation speed.

Q3: Vertical scratches & streaks on pipe inner/outer surface

Reasons: Scratched mold inner cavity, accumulated impurities, worn die lip, precipitated lubricant residues. Solutions: Polish mold surface; disassemble & clean die regularly; replace damaged die lip.

Q4: Bubbles & blisters inside pipe wall

Reasons: Excessive moisture in raw materials; cooling water seepage into un-solidified pipe. Solutions: Dry pellets before production; check sealing of sizing sleeve to stop water leakage.

Q5: Traction speed jitter, slipping between pipe & traction pads

Reasons: Worn rubber traction pads, uneven clamping pressure, unstable VFD control. Consequence: Fluctuating pipe size & wall thickness. Solutions: Replace aging rubber pads; adjust clamping force; recalibrate traction inverter.

Q6: Indentations & compression marks on pipe surface

Reason: Over-tight clamping force of haul-off tracks. Solution: Loosen traction pressure appropriately.
