Ablation casting
From Wikipedia, the free encyclopedia
Ablation casting is a sand casting process that uses water to wash away the mold while the metal solidifies. This process produces castings with high mechanical properties, reduced defects, and a fine microstructure.
There are three steps in the ablation casting process:
- Mold preparation: A mold is made from sand particles bonded with a water-soluble binder.
- Filling: The mold is filled with molten metal.
- Ablation: While the metal is still molten, a spray of water erodes away the mold. The water allows direct contact with the metal, which eliminates the air gap that usually forms in other casting processes.
