Injection Molding
8 조회수
Product severe surface floating fibers
문제 현상
Bare glass fibers are visible on the product surface, the surface is rough and prickly to the touch
원인 분석
The PP matrix has poor impregnation with glass fibers; excessive injection speed pushes fibers to the surface; the mold temperature is too low and PP quenches too fast to fully wrap the fibers
해결 방법
Improve the glass fiber coupling agent treatment level (silane coupling agent); reduce injection speed by 30-50%; increase mold temperature to 80-100°C to form a PP skin layer
핵심 요약
Floating fibers are the most typical and common appearance quality problem in LGFPP processing
