TPE Silver Streak
문제 현상
Silver streaks appear on the product surface.
원인 분석
Material moisture vaporization or degradation gas is sheared and stretched during filling; U-shaped streaks mostly point to moisture, scattered streaks mostly point to air entrapment.; during on-site troubleshooting, verify item by item according to this mechanism, avoiding blind machine adjustment based solely on experience
해결 방법
①Judge the cause by morphology then treat accordingly; ②strengthen drying for the moisture type; ③raise back pressure and reduce speed for the air type; ④verify and confirm variable by variable.; after adjustment, continuously sample to verify the effect, and resume mass production only after confirming stability
핵심 요약
Silver streak morphology is the key to cause judgment; check drying for U-shape, air for scattered, degradation for shiny; variable-by-variable verification locates the fastest.; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence
