Two hundred and forty-three wax patterns are  assembled  on a  6" diameter sprue to form the casting tree. ( Partial pattern assembly shown to the right)

The tree is then invested (coated) with ceramic by dipping the tree into a ceramic slurry bath.

After wax removal, the finished mold is placed in the casting chamber and the chamber is back filled with a  22 mesh mullite sand.

• The sand in the chamber supports  the mold and reduces the number of investments needed, saving production time.

• The sand also improves thermal uniformity and heat management in the mold chamber.
