Temperature Control and Maintenance of PEEK Hot Runner
문제 현상
[Problem Phenomenon] Gate blockage and degradation carbonization alternate in the PEEK hot runner system
원인 분석
The hot runner requires precise temperature control of 375-390℃ — deviation causes either freezing blockage or overheating carbonization; a damp heater will also short-circuit and be damaged at startup, so it must be fully dried before startup
해결 방법
Control the hot runner temperature at 375-390℃ with independent closed-loop zones; dry the heater to remove moisture before startup; design the gate area temperature gradient to prevent freezing; regularly clean carbon deposits
핵심 요약
PEEK hot runner temperature control at 375-390℃ is delicate work, and drying and dehumidifying before startup cannot be omitted; after confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence
