EVA foaming density testing
Fenómeno del problema
Inconsistent density testing methods cause quality disputes.
Análisis de la causa
The density of foamed products is affected by sampling position and testing method; different methods of the supply and demand sides give different results.; during on-site troubleshooting, verify item by item according to this mechanism, and avoid blindly adjusting the machine based on experience alone
Solución
①Unify the testing method and sampling position; ②agree on testing standards; ③benchmark verification between both parties; ④record testing conditions.; after adjustment, take consecutive samples to verify the effect, and resume mass production only after confirming stability
Conclusión clave
Testing standardization is the foundation of quality cooperation; method unification is more important than the numerical value.; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence
