TPE Mold Temperature Uniformity
Fenómeno del problema
The hardness of TPE products is inconsistent across different parts
Análisis de la causa
Uneven mold cooling causes different phase structures; 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
Homogenize water channels; cavity temperature difference ±3℃; strengthen water channels at thick walls; 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
TPE hardness uniformity relies on mold temperature uniformity; 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
