Sand Casting
- Predict Porosity originated by Shrinkage formation
- The SIGAP (Shrinkage Induced Gas Porosity) model predicts
- You can accurately predict shrinkage porosity which other model can’t
- SIGAP
- Gas Pressure, Surface Tension applied Pressure
Metallostatic Pressure, Carbon Expansion Pressure, Shrinkage Pressure
- This shrinkage caused
by gas porosity originated
from shrinkage formation - SIGAP
Shrinkage Induced Porosity - RMM
