MP length out of tolerance
문제 현상
MP product length deviation >±0.5mm, exceeding the tolerance
원인 분석
MP shrinkage rate unstable, fluctuating ±0.5%; mold dimension design did not consider shrinkage compensation; insufficient cooling, dimensions not stabilized
해결 방법
1) precisely measure the MP shrinkage rate and compensate the mold; 2) fully cool to ensure dimensional stability; 3) annealing to eliminate post-shrinkage
핵심 요약
length out of tolerance is caused by unstable shrinkage rate; precise shrinkage compensation is key
