Tooling and Pattern Making
A tool is built to customer- provided specifications (A). Cold wax wax is then injected into the tool to create a wax
pattern/prototype (B) that will hold precise dimensional requirements in the final casting.

Pattern Assembly
The wax patterns are assembled onto the sprue.

Dipping and Coating
Successive layers of ceramic (A) and stucco (B) are applied to the sprue assembly to form a hard shell.

De-Waxing and Firing
The molds are flash- fired to remove the wax and sprue materials and then heated to 1,800° and placed on a sand bed, ready for pouring.

Casting
Molten metal, up to 3,000°, is poured into the hollow mold and then cooled.
