Balance Between Vent Depth and Flash of PEEK

문제 현상
[Problem Phenomenon] Trapped-air burning and flash at the vents coexist on PEEK products, and deepening the vent grooves causes overflow
원인 분석
PEEK melt has low viscosity and easily overflows the edge, so the vent groove depth must be controlled within the precise range of 0.02-0.025mm; too shallow causes trapped-air burning, too deep causes flash
해결 방법
Precision-machine the vent groove depth at 0.02-0.025mm and clean it regularly; for trapped-air areas, prioritize optimizing the gate and injection speed profile; for flash, check the clamping and parting line fit
핵심 요약
PEEK venting is 0.02mm-level fine work — depth precision is more important than deepening; after confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence
