ABS annealing deformation recurrence
Fenómeno del problema
[Problem Phenomenon] ABS stable short-term after annealing, recurrence after storage
Análisis de la causa
Annealing temperature and time insufficient; amorphous annealing window narrow; during on-site troubleshooting, verify item by item according to this mechanism, avoid blindly adjusting the machine based only on experience; this mechanism has been repeatedly verified by industry materials and should be confirmed first during troubleshooting
Solución
Hold at heat distortion temperature -10~15℃ for sufficient time; slow cooling; verify storage; after adjustment, continuously sample to verify the effect, resume mass production only after confirming stability; change only one variable each time and record parameter changes to facilitate locating effective measures
Conclusión clave
ABS annealing temperature and time must be sufficient, slow cooling sets the shape; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence; include this case in the defect archive as a troubleshooting reference for similar problems later
