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: Material yellowing, black burnt spots & decomposition lines

General causes: Long material residence time, damaged temperature sensors, degraded recycled materials or local overheating. Solutions: Lower overheated zone temperature; clean mold dead zones; verify PPR resin quality and production temperature settings.

Q4: Extruder overload & high motor current alarm

Reasons: Low barrel temperature, blocked screen pack, foreign objects inside barrel, excessive filler content. Solutions: Raise temperature moderately; replace screen mesh; clean foreign debris; adjust filler proportion.

Q5: 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 and clean die regularly; replace damaged die lip.

Q6: Severely uneven pipe wall thickness

Reasons: Offset mold center, unbalanced heating rings around die, partial blocked melt channels. Solutions: Re-center the mandrel; check and replace faulty heating bands; clear blocked flow paths.

Q7: Melt leakage from mold joint gaps

Reasons: Loose clamping bolts, aging sealing gaskets, uneven thermal expansion of die components. Solutions: Retighten bolts evenly; replace damaged gaskets; balance mold heating temperature.

Q8: Spiral ripples inside finished pipes

Reasons: Unbalanced melt flow inside mold, unreasonable mandrel structure, unstable melt pressure. Solutions: Optimize internal mold flow channel design and stabilize extruder output pressure.
