Glass Fibre product elliptical deformation
Problembeschreibung
Glass Fibre circular products have ovality >1.03 after demolding
Ursachenanalyse
asymmetric demolding force, product deformed by lateral force; uneven cooling, shrinkage differs in all directions
Lösung
1) uniform ejection design with 8-point ejection to avoid lateral force; 2) annular uniform cooling; 3) extend cooling time for full setting
Wichtigste Erkenntnis
elliptical deformation is caused by asymmetric demolding force; uniform ejection is key
