EMA length out of tolerance
Fenómeno do problema
EMA product length deviation >±0.5mm, exceeding tolerance
Análise das causas
EMA shrinkage rate unstable, fluctuating ±0.5%; mold dimension design did not consider shrinkage compensation; insufficient cooling with dimensions not stabilized
Solução
1) Precisely measure EMA shrinkage rate and compensate the mold; 2) Cool sufficiently to ensure dimensional stability; 3) Annealing treatment to eliminate post-shrinkage
Conclusão principal
Length out of tolerance is caused by unstable shrinkage rate; precise shrinkage compensation is key
