The Jewelry Manufacturing - Process Of Casting Bracelet From Beginning To End

Jewelry making is a wonderfully innovative business. There is nothing rather like making gorgeous new shapes out of precious metals and gemstones that your customers will cherish and love for years to come. Throughout the years, the wax casting procedure hasn’t just been used for jewelry, but it was also used to make sculptures and ornaments. 

Also, one of the main benefits of wax casting is that you can repeat the same model as many times as you’d like. The possibilities of creation with castings are endless. The casting jewelry process captures even the most minor details and is cost and time effective; it helps you to make multiples of the same pieces. 
 

Casting is a part of a similar jewelry creation process. It allows us to take an idea or design, assemble a mold, and ultimately create a physical replica of the final product. 

CAD & CAM - To cast jewelry, you need a master sample. Traditionally, one used to be carved by hand to use after in the model-making process. But, unquestionably, computers have changed the landscape of every industry, and a clear illustration of this is the method & technology being used in CAD jewelry designs. Artisans develop CAD jewelry designs on computer screens using equipment and software that metamorphose their thoughts and keystrokes into creations of art. These are then transformed from data to a 3D wax or resin form. 
 

 

Wax model - Using the CAD design, a liquid dye is made, and a wax model is carved or printed to illustrate the finished piece in three dimensions. Then a rubber mold is crated with a 3D design and is injected with wax to create the jewelry piece form. After the wax hardens up, it is removed and inspected for quality.

Casting Preparation - These are joined to a wax stem by a sprue. This will form the canal through which the molten silver will flow once the mold is created. Numerous wax models can be attached to form a tree or left as single models and placed in a cylinder mold. Building a tree allows the jeweler to cast multiple jewelry pieces at once.

POP Flask - The wax stem and the attached models are placed in a unique frame called a flask and is surrounded by an investment material called POP. The cylinder is filled with investment to cover the wax completely. Once the investment material like POP sets, it hardens into the mold for the jewelry. Vacuum pressure is created to remove all the air bubbles from the cylinder to make a perfect mold. Any air bubbles compromise the quality of the casting.

Burnout - After the Plaster of Paris material hardens, the flask is placed in a special kiln to boil away the wax, which leaves a hollow in the POP material that becomes the final mold. The mold now has a tree-shaped cavity that is ready for casting.

Melting - The silver is melted, and depending on the type of metal used, temperatures can range from 1,617 degrees Fahrenheit and 2,006 degrees Fahrenheit. Silver can be combined with other metals like gold, copper, and palladium to create alloys of varying colors and hardness.

Casting - In this step, the precious metal of your choice is melted and poured into the plaster mold. The liquid metal is then flowed into the mold to ensure a higher-quality casting. The metal, like silver, flows into every area of the mold evenly. Once the molten silver is poured into the cast, it is kept aside for cooling, and metal replicas are removed from the flask.

Divesting - Once the metal cools, it needs to be removed from the investment material. This is done through physical means by first quenching in the water while it is still hot and then putting it under the pressure of water to remove all the bits and pieces of POP. Each casting is then cleaned and polished, and the sprues are cut- off for recycling.

Finishing - The sprue and other extra metal will be trimmed away, but many imperfections will stay. There might be edges and seams to grind out, specifically if it was made with multiple castings in a tree formation. Now remove the sprue, polish the jewelry piece, do the rhodium or gold plating, and finally set it with the perfect gem. 

Tumbling - The next step in finishing your jewelry castings is tumble finishing. Tumbling is a method where your piece is “tumbled” around a cask with other materials to clean, smooth, and illuminate it, bringing it one step closer to the final piece. 
The cask of the device is filled with whatever medium you choose and a lubricant like water and then rotated to tumble the materials together. As a result, your jewelry pieces will appear smoother and shinier with each round. 

Polishing - Polishing is a stage where any remaining flaws are removed, and your castings are thoroughly groomed and polished to a brilliant shine.
