Uneven cutting end face of polyolefin plastomer pipes (Variant: Enhanced Measures)
Problembeschreibung
The pipe end face has burrs, tilting, or cracking after cutting.
The uneven cutting end face affects the pipe connection quality and may cause leakage in welding and socket connections.
In particular, additional attention is needed on the original basis; this problem is more prominent and requires focused attention.
Ursachenanalyse
（1）The cutting tool is worn or the edge is not sharp
（2）The cutting speed is too fast or the cutting pressure is too large
（3）The pipe temperature is too high and it deforms during cutting
（4）The cutting machine is installed incorrectly and the cutter is not perpendicular to the pipe
（5）The pipe wall thickness is uneven and the cutting force is uneven
（6）On the original basis, additional attention is needed: fluctuations in process parameters or changes in equipment status have aggravated this problem
Lösung
（1）Replace or sharpen the cutting tool
（2）Adjust the cutting speed and pressure to ensure smooth cutting
（3）Ensure the pipe is fully cooled before cutting
（4）Correct the installation of the cutting machine, with the cutter perpendicular to the pipe axis
（5）Ensure uniform pipe wall thickness
（6）And strengthen process monitoring; on the original basis, additional attention is needed to pay special attention to parameter stability
Wichtigste Erkenntnis
The uneven cutting end face is caused by tool wear or improper cutting parameters, and the tool needs to be maintained and the cutting process optimized.
Targeted preventive measures need to be taken in different production scenarios.
