TPE Seal Application
Fenómeno del problema
TPE seals are soft and easy to assemble, but have large compression set at high temperature
Análisis de la causa
TPE seals are soft, easy to assemble, and low cost; but at high temperature the compression set is large and the sealing force decays; TPV or rubber is more suitable for high-temperature sealing; during on-site troubleshooting, verify item by item according to this mechanism, and avoid blindly adjusting the machine based solely on experience
Solución
①Choose TPE for room-temperature sealing; ②Choose TPV or rubber for high-temperature sealing; ③Verify compression set by working conditions; after adjustment, continuously sample to verify the effect, and resume mass production only after confirming stability
Conclusión clave
The temperature boundary of TPE seals is clear; room temperature is the main battlefield, high temperature gives way to TPV; after confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence
