TPE Extrusion Melt Pressure
Fenómeno del problema
Unstable TPE extrusion output causes product dimension fluctuation
Análisis de la causa
Melt pressure fluctuation; during on-site troubleshooting, verify item by item according to this mechanism, and avoid blindly adjusting the machine based solely on experience; this mechanism has been repeatedly verified by industry information and should be confirmed first during troubleshooting
Solución
Melt pressure closed loop; stable feeding; screen monitoring; after adjustment, continuously sample 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
Extrusion stability relies on melt pressure closed loop; after confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence; include this case in the defect archive as a reference for troubleshooting similar problems in the future
