TPE Workshop Humidity
Fenómeno del problema
During the plum rain season, the bubble and silver streak rate of TPE products increases, with different results at the same parameters
Análisis de la causa
Increased ambient humidity accelerates moisture absorption of TPE after opening the package; the drying load increases; the hard plastic of overmolded parts is also dampened; seasonal compensation is a necessary measure; during on-site troubleshooting, verify item by item according to this mechanism, and avoid blindly adjusting the machine based solely on experience
Solución
①Extend drying time and intensify sampling inspection during the rainy season; ②Connect the hopper to dry air; ③Workshop dehumidification reduces ambient humidity; after adjustment, continuously sample to verify the effect, and resume mass production only after confirming stability
Conclusión clave
Seasonal quality fluctuations of TPE originate from ambient humidity; rainy season compensated drying plus workshop dehumidification keeps the weather out; after confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence
