Demolding and Finishing

After the aluminum has cooled enough to solidify the sand is removed from around the part.

All of the burnt sand is wire brushed off of the part. Care is taken to recover as much of the sand as possible as it can be reused many times.

Once the bulk of the sand is removed the part is rapidly cooled in water. The rough casting is shown here on the molding board.

The runner system broke off the part while handling them. With this part, the flashing (the little bit of metal that worked its way through the mold parting line) will be removed with a sander.

The flat faces will be trued up on the sander. No additional machining is needed.
