Dating back to ancient times, lost wax casting is a form of metal casting that continues to be one of the most reliable and commonly used methods in jewelry manufacturing and reproduction today. At Frank Billanti Casting Company in New York City, this classic method has created gorgeous jewelry pieces that stand the test of time.

5 Steps Of Lost Wax Casting

Carving The Wax Model

The first step in lost wax casting is the wax model. Thanks to the malleability of wax, artists can carve the finest details. However, because of this level of precision, Frank Billanti Casting Company first renders a thorough virtual model using Computer-Aided Design (CAD) technology before ever handling the wax. This allows them to confirm it's made exactly to their client's specifications.

Making The Rubber Molds

Once both the design and wax model are approved, the jewelry manufacturer covers the model in liquid rubber to create a hollow mold. Frank Billanti Casting Company uses Castaldo rubber materials so that the final products always maintain a fine detail.

Creating The Plaster Mold & Losing The Wax

With the rubber mold completed, another wax model is made and then encased in plaster. Before it is thrown into the kiln to set, a small passage is carved. As the heat intensifies, the wax melts away through the small passage.

Casting The Metal

With the empty plaster mold completely hardened, molten metal can now be poured in. Frank Billanti Casting Company offers a wide variety of both base and precious metals, so whatever the design may be, it's all up to the client! After the metal has set and cooled, the plaster mold can be broken to reveal what's inside.

Cleaning It Up

Because of the small passage made to pour in the metal, there will be a small piece that needs to be removed. Once that's gone and meticulously filed down, the item is then tumbled in a polisher. At Frank Billanti Casting Company, they offer a wide selection polishing types, from high shine to a light, organic-looking appearance.
