Product dimensional accuracy difficult to control
문제 현상
PEI products have large dimensional deviations, making it difficult to meet precision fit requirements
원인 분석
PEI shrinkage rate (0.5-1.0%) is very sensitive to mold temperature and holding conditions; every 1°C of mold temperature fluctuation can cause a shrinkage rate change of 0.02-0.05%
해결 방법
Strictly control mold temperature within ±2°C; optimize the setting of holding pressure and time; correct mold dimensions based on actual measured shrinkage rate
핵심 요약
The dimensional accuracy of PEI products is highly dependent on the stability of process parameters
