LLDPE hot runner
Fenómeno do problema
Gate stringing in LLDPE hot runner molds
Análise das causas
Hot runner temperature is too high and viscosity is low; when troubleshooting on site, verify item by item according to this mechanism to avoid blindly adjusting the machine based only on experience; this mechanism has been repeatedly verified by industry data and should be confirmed first during troubleshooting
Solução
Calibrate hot runner temperature; cool the gate area; 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
Conclusão principal
Stringing is controlled by gate temperature; after confirming effectiveness, fix 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
