PA66 '2079851475616104452 cycle fluctuation
Fenómeno del problema
Cycle varies long and short, quality unstable.
Análisis de la causa
Plasticizing time fluctuation (feeding/back pressure), temperature control drift; unstable plasticizing transmits into cycle fluctuation; during on-site troubleshooting, verify item by item according to this mechanism, and avoid blindly adjusting the machine based solely on experience.
Solución
①Stabilize feeding and back pressure; ②calibrate the temperature control system and thermocouples to ensure accurate temperature; ③monitor plasticizing time changes as an early warning of plasticizing stability; ④stabilize regrind blending ratio and mix uniformly; ⑤check screw wear and mixing state.
Conclusión clave
PA66 cycle='plasticizing stability': plasticizing time is a leading indicator; stabilize feeding and back pressure, and the cycle can be stable; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence.
