PP Surface Hardness Scratch
문제 현상
【Problem Phenomenon】PP product surfaces are scratched and worn
원인 분석
PP surface hardness is low and easily scratched; obvious on high-gloss appearance parts; during on-site troubleshooting, verify item by item according to this mechanism to avoid blindly adjusting the machine based only on experience; this mechanism has been repeatedly verified by industry data and should be confirmed first during troubleshooting
해결 방법
Protection during transfer; surface coating; high-hardness grades or fillers; after adjustment, take continuous samples to verify the effect, and resume mass production only after confirming stability; change only one variable at a time and record parameter changes to facilitate locating effective measures
핵심 요약
PP fears scratching, protective coating plus hard fillers; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence; include this case in the defect archive as a troubleshooting reference for similar problems in the future
