EVA length out of tolerance
Fenómeno del problema
EVA product length deviation >±0.5mm exceeds tolerance
Análisis de la causa
EVA shrinkage rate unstable, fluctuating ±0.5%; mold dimension design did not consider shrinkage compensation; insufficient cooling with dimensions not stabilized
Solución
1) Accurately measure EVA shrinkage rate and compensate the mold; 2) Sufficient cooling to ensure dimensional stability; 3) Annealing treatment to eliminate post-shrinkage
Conclusión clave
Length out of tolerance is caused by unstable shrinkage rate; precise shrinkage compensation is key
