EAA length out of tolerance
문제 현상
EAA product length deviation >±0.5mm exceeding tolerance
원인 분석
EAA shrinkage rate unstable with fluctuation of ±0.5%; mold dimension design did not consider shrinkage compensation; insufficient cooling, dimensions not stabilized
해결 방법
1) Accurately measure EAA shrinkage rate and compensate the mold; 2) Cool sufficiently to ensure dimensional stability; 3) Anneal to eliminate post-shrinkage
핵심 요약
Length out of tolerance is caused by unstable shrinkage rate; accurate shrinkage compensation is key
