POM Injection Speed Strategy
문제 현상
Too slow speed causes ripples on the part; too fast causes jetting marks and shear overheating discoloration
원인 분석
POM injection speed should be medium-fast: too slow causes fast freezing and ripples; too fast causes shear overheating and jetting marks; use faster speed for thin walls with high dimensional precision, and slower speed when thick walls have void and flow mark problems
해결 방법
①Normally inject at medium-fast speed; ②speed up for thin-wall precision parts and slow down for thick-wall parts; ③when jetting marks appear, reduce speed and check gate shear; after adjustment, take continuous samples to verify the effect, and resume mass production only after confirming stability
핵심 요약
POM speed strategy is a balancing act of medium-fast; fine-tune in both directions according to wall thickness and defect type, avoiding the two extremes; after confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence
