PCL insert molding
Fenómeno del problema
PCL metal or ceramic insert molding, interfacial bonding and stress problems.
Análisis de la causa
Thermal expansion differences between PCL and inserts; interfacial bonding; molding stress; cooling shrinkage; long-term performance.；During on-site troubleshooting, verify item by item according to this mechanism, and avoid blindly adjusting the machine based solely on experience
Solución
①Insert preheating; ②Interfacial design; ③Process optimization; ④Long-term testing.；After adjustment, take continuous samples to verify the effect, and resume mass production only after confirming stability；Change only one variable at a time and record parameter changes to facilitate locating effective measures
Conclusión clave
Interfacial management of PCL insert molding is the key; both preheating and design are emphasized; testing ensures reliability.；After confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence
