Problembeschreibung
Products break brittlely under force.
Ursachenanalyse
Thermal decomposition breaks molecular chains; or stress concentration at inserts/sharp corners; too much regrind.
Lösung
①Control melt temperature to prevent decomposition; ②structural fillets; ③control regrind; ④check hot runner temperature.
Wichtigste Erkenntnis
Brittle cracking = decomposition or stress, distinguish first by smelling the odor.
