POM Injection Pressure Grading
문제 현상
Small-gate thin-wall long-flow parts are underfilled, while general parts produced with the same parameters get flash
원인 분석
POM injection pressure is graded by structure: 40-80MPa for large-gate short-flow small-area parts, about 100MPa for general parts, and 120-140MPa for small-gate thin-wall long-flow large-area parts
해결 방법
①Set injection pressure graded by part structure; ②use 120-140MPa for thin-wall long-flow parts; ③the flash threshold is 0.04mm—excessive pressure immediately causes flash
핵심 요약
POM pressure setting must be graded by structure; the wide range of 40-140MPa means one-size-fits-all parameters will inevitably sacrifice one aspect for another; after confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence
