ABS warpage internal stress
Fenómeno del problema
ABS warpage internal stress, non-uniform cooling or insufficient draft angle, stress management.
Análisis de la causa
ABS warpage internal stress; non-uniform cooling; insufficient draft angle; wall thickness difference; uneven mold temperature; excessive holding pressure; structural design.; During on-site troubleshooting, verify item by item according to this mechanism, and avoid blindly adjusting the machine based only on experience
Solución
①Uniform cooling; ②draft angle 1.5-2°; ③uniform wall thickness; ④mold temperature management; ⑤holding pressure optimization.; After adjustment, continuously sample to verify the effect, and resume mass production only after confirming stability
Conclusión clave
Cooling and draft angle are the foundation for ABS warpage; wall thickness and mold temperature are both important; holding pressure balance prevents stress.; After confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence
