What goes into the design and manufacturing process of your custom piece of jewelry.
Investment casting (lost-wax casting) is a process that has been practiced for thousands of years, with lost wax process being one of the oldest known metal forming techniques. From 5000 years ago, when bees wax formed the pattern, to today’s high technology waxes, refractory materials and specialist alloys, the castings ensure high quality components are produced with the key benefits of accuracy, repeatability, versatility and integrity.

In Jewelry Lost Wax Casting process, a wax mold is used to create a piece of jewelry. This wax mold, called a pattern, is first weighed so the amount of metal required to fill the mold (gold, silver, etc.) can be determined. |
 |
Then the mold is attached to a base, and a flask is fit over the base. |
 |
Once the mold is in the flask, a kind of plaster that looks like pan cake batter, called investment, is mixed up, put in a vacuum to get all the air bubbles out of it, and then poured into the flask. It is then left to dry and harden. This takes a minimum of two hours. |
 |
Once the investment is dried, the base and flask are removed. Now the piece is put into an oven to burn out the wax. |
 |
Next a centrifuge is used to force the melted metal into the investment mold. |
| |
Finally, the piece is cleaned up by filing and polishing it. |
