PA66 warpage deformation
Sorun Belirtisi
PA66 flat parts warp out of the mold, and assembly gaps exceed standard
Neden Analizi
Large crystallization shrinkage and uneven cooling produce shrinkage differences; glass fiber orientation makes anisotropy more obvious, and flat parts are most sensitive; during on-site troubleshooting, verify item by item according to this mechanism, avoiding blindly adjusting the machine based only on experience
Çözüm
Balance cooling water circuits; multi-point gating for symmetric flow; raise mold temperature to homogenize shrinkage; use setting fixtures for assistance when necessary; after adjustment, take continuous samples to verify the effect, confirm stability before resuming mass production
Temel Çıkarım
Warpage treatment centers on cooling balance and flow symmetry; after confirming effectiveness, fix the parameters and practices into the work instructions to prevent recurrence; include this case in the defect archive as a troubleshooting reference for subsequent similar problems
