Large shrinkage rate of POM '2079851475616104452
Sorun Belirtisi
POM crystalline shrinkage rate 1.8-2.5% is high and anisotropy is large.
Neden Analizi
POM has high crystallinity (70-80%), large volume shrinkage during cooling, and large shrinkage difference between flow direction and perpendicular direction.
Çözüm
Reserve more shrinkage allowance in mold design; increase holding pressure time and pressure; uniform cooling.
Temel Çıkarım
POM high shrinkage is the primary consideration in precision '2079851475616104452 design.
