TPE Product Bubbles (Volatilization)
Fenómeno del problema
Bubbles increase during high-temperature processing.
Análisis de la causa
Oils and additives in TPE volatilize at high temperature; the higher the temperature, the more obvious the volatilization.; during on-site troubleshooting, verify item by item according to this mechanism, avoiding blind machine adjustment based solely on experience; this mechanism has been repeatedly verified by industry data and should be confirmed first during troubleshooting
Solución
①Control the processing temperature; ②evaluate the additive system; ③strengthen venting; ④confirm with the supplier.; after adjustment, continuously sample to verify the effect, and resume mass production only after confirming stability
Conclusión clave
Volatilization-type bubbles require temperature control; the additive system is fundamental.; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence; include this case in the defect archive as a troubleshooting reference for subsequent similar problems
