PVA angle deviation
Problembeschreibung
PVA product angle deviation >1°, exceeding the ±0.5° tolerance
Ursachenanalyse
Uneven shrinkage causes angle change; mold angle design did not consider PVA shrinkage compensation; product deformation during demolding
Lösung
1) Mold angle pre-compensation for the PVA shrinkage rate; 2) Extend cooling time to ensure setting before demolding; 3) Uniform cooling to reduce shrinkage differences
Wichtigste Erkenntnis
Angle deviation is caused by shrinkage and insufficient design compensation; pre-compensation is the key
