Improper PESU Mold Temperature
문제 현상
PESU products have high internal stress or poor surface quality; mold temperature deviates from the 149~163℃ range.
원인 분석
PESU mold temperature of 149~163℃ obtains low internal stress and high-performance products; low temperature means high stress and poor surface; high temperature means long cycle and mold sticking; uniformity affects consistency.
해결 방법
①Control mold temperature at 149~163℃; ②temperature uniformity management; ③balance stress and cycle; ④actually measure mold cavity temperature.; after adjustment, continuously sample to verify the effect, and resume mass production after confirming stability
핵심 요약
The 149~163℃ of PESU mold temperature is the supplier standard; uniformity ensures consistency; balance optimization is based on verification.; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence
