Sand Casting

A sand cast part from BIAN is one that has undergone the sand casting process.

 

First, a mold with a specific geometry must be created. Then, sand is packed around this mold. There are typically two molds, one for each half of the sand cast component being made.

 

The mold is removed and a cavity in the shape of the mold is left in the sand. The two halves are then lubricated on their surface areas. They are then clamped together and molten metal is poured into the cavity, which resembles the shape of the sand cast part.

 

After cooling, the sand cast part is removed, which is typically done by breaking the mold.
