CEF length out of tolerance
Fenómeno del problema
The length deviation of the CEF product is >±0.5mm, exceeding the tolerance
Análisis de la causa
The CEF shrinkage rate is unstable and fluctuates ±0.5%; the mold size design does not consider shrinkage compensation; the cooling is insufficient and the size is not stabilized
Solución
1) Accurately measure the CEF shrinkage rate and compensate the mold; 2) Fully cool to ensure dimensional stability; 3) Annealing treatment to eliminate post-shrinkage
Conclusión clave
Length out of tolerance is caused by unstable shrinkage rate; accurate shrinkage compensation is the key
