Warpage Deformation in CMC '2079851475616104452
Sorun Belirtisi
After demolding, CMC injection molded products warp 2-3mm/100mm and the flatness does not meet the standard
Neden Analizi
CMC shrinkage is large and mold temperature is uneven, causing differential shrinkage in all directions; improper gate position causes uneven release of flow orientation stress; insufficient cooling time
Çözüm
1)Increase 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 differential shrinkage and orientation stress; uniform mold temperature and holding pressure are the key
