PP Thin-Wall High-Speed Part Defects
문제 현상
【Problem Phenomenon】PP ultra-thin-wall high-speed molding has both flash and short shots
원인 분석
Under ultra-thin-wall high speed, the melt shear and temperature management window is extremely narrow; high-MFI material flashes easily but fills well; during on-site troubleshooting, verify item by item according to this mechanism to avoid blindly adjusting the machine based only on experience
해결 방법
High-MFI grades with precise pressure and speed; clamping verification to prevent flash; cavity pressure monitoring; after adjustment, take continuous samples to verify the effect, and resume mass production only after confirming stability
핵심 요약
PP ultra-thin-wall high speed is an extreme process, precise control of pressure and speed; 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
