PA6 Glass Fiber Reinforced Warpage
문제 현상
Glass fiber reinforced PA6 parts show obvious warpage, flatness out of tolerance, and uneven assembly gaps
원인 분석
Glass fiber orientation makes PA6 shrink only 0.3% in the flow direction but up to 1% in the perpendicular direction, and the anisotropic shrinkage difference causes warpage; improper gate position further amplifies the orientation difference
해결 방법
①Position the gate so that fibers orient uniformly along the main direction; ②Homogenize mold temperature and use conformal cooling channels to reduce temperature difference; ③For flat parts, use a shaping fixture for 24 hours to reduce warpage by 40-60%
핵심 요약
The essence of glass fiber PA6 warpage is orientation anisotropy; gate design and uniform-temperature cooling are the source countermeasures, and the shaping fixture is an effective remedy; after confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence
