The vacuum sand casting process begins with the preparation of a sand mold, which is typically made of a mixture of sand and a binding agent. In traditional sand casting, the mold is often subject to atmospheric pressure, which can lead to defects such as gas porosity and inclusions in the final cast product. Vacuum sand casting, however, mitigates these issues by creating a vacuum inside the mold cavity before the molten metal is poured.
