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