POE '2079851475616104452 warpage deformation
Sorun Belirtisi
POE injection molded product warps 2-3mm/100mm after demolding, flatness does not meet standard
Neden Analizi
POE shrinkage is large and mold temperature is uneven, causing anisotropic shrinkage differences; improper gate position, flow orientation stress is released unevenly; cooling time insufficient
Çözüm
1) Raise mold temperature to 40-60°C to reduce temperature difference; 2) Increase holding pressure 50-70MPa; 3) Optimize gate position for uniform flow; 4) Extend cooling time; 5) Annealing treatment to release residual stress
Temel Çıkarım
Warpage is caused by shrinkage difference and orientation stress; uniform mold temperature and holding pressure are key
