HDPE Demolding Deformation
Fenómeno do problema
HDPE product deforms after ejection
Análise das causas
Demolding temperature is too high and rigidity insufficient, or ejection is uneven; during on-site troubleshooting, verify item by item according to this mechanism to avoid blindly adjusting the machine based solely on experience; this mechanism has been repeatedly verified by industry data and should be confirmed first during troubleshooting
Solução
Extend cooling time; balance ejection; optimize mold temperature; 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
Demolding deformation relies on cooling and balanced ejection; 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
