POM Glass Fiber Reinforced Deformation
Problembeschreibung
Glass fiber reinforced POM parts warp, with poor dimensional accuracy, surface floating fibers, and poor gloss
Ursachenanalyse
Glass fiber orientation anisotropy causes warpage; fibers floating to the surface form floating fibers; reinforced grades have lower shrinkage but stronger directionality, and mold margin must be corrected by grade
Lösung
①Control fiber orientation via gate position; ②raise mold temperature to improve surface replication; ③correct mold shrinkage margin according to reinforced grade data; after adjustment, take continuous samples to verify the effect, and resume mass production only after confirming stability
Wichtigste Erkenntnis
Glass fiber POM trades directionality for strength; orientation design and shrinkage correction are required courses at the mold stage; after confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence
