The difference between the gas porosity and shrinkage cavity in casting process (2)

1) when non-ferro alloy is melted, charge, solvent, tool and ladle should be preheated and dried fully, rust and oil should be removed, and the amount of charge should be properly limited.

The difference between the gas porosity and shrinkage cavity in casting process (1)

Click here casting production, casting gas porosity, and casting shrinkage cavity are sometimes associated, sometimes in separate groups. When gas porosity and shrinkage cavity occur, we quickly determine whether the defect is a gas porosity or a shrinkage cavity is necessary to solve the problem. To quickly judge these two defects, you know their characteristics well at first. Today, we teach you […]
