PA6 '2079851475616104452 Cycle Too Long
문제 현상
Slow cycle, limited capacity.
원인 분석
High mold temperature and slow cooling, large wall thickness; low water channel efficiency also lengthens the cycle; during on-site troubleshooting, verify item by item according to this mechanism, and avoid blindly adjusting the machine based only on experience; during troubleshooting, confirm item by item around key factors such as molding cycle and cooling to avoid misjudgment.
해결 방법
①Unblock and optimize water channels, and calculate flow and temperature difference;②core-pull and reduce material at thick walls to reduce shrinkage from the source;③balance mold temperature setting and molding cycle;④use conformal water channels or beryllium copper inserts at thick walls;⑤optimize product structure to reduce thick walls and wall thickness sudden changes.
핵심 요약
PA6 cycle = 'cooling efficiency': start from water channels and wall thickness; cooling accounts for the bulk of the cycle, and efficiency improvement first cuts cooling time; after confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence.
