PP High-Flow Grade Processing
문제 현상
[Problem Phenomenon] Processing high-flow PP thin-wall parts, the window between flash and short shot is narrow
원인 분석
High-flow PP (MFI 20-60 or even 100) flashes easily but fills well; injection pressure and speed need precise control; thin-wall high-speed molding; during on-site troubleshooting, verify item by item according to this mechanism, and avoid blindly adjusting the machine based on experience alone
해결 방법
Precisely control pressure and speed for high-flow grades; check clamping force to prevent flash; leverage its filling advantage for thin-wall parts; after adjustment, take continuous samples to verify the effect, and resume mass production only after confirming stability
핵심 요약
For PP high-flow material, prevent flash; thin-wall filling is its strength; 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 future problems
