What is jewelry casting? Jewelry casting is an art that has been long used for thousands of years for jewelry making. With improvements in technology and the advent of superb tools and machinery, jewelry casting is an art that is more dynamic today than ever. Whether you want custom-made piece of jewelry or have to make a bulk order of similar types of jewelry, casting is a process that can help you achieve both.
Also called jewelry wax casting, casting uses a wax pattern that is made into a mold for being filled with molten silver or metal to create an intricate piece of jewelry.
The process involve great temperatures and even greater precision for excellent results. Jewelry casting is a process that has allowed designers and jewelry makers to bring their ideas to life and produce gorgeous pieces of jewelry. There are 4 steps to the basic process of jewelry casting.
Creating the Mold
Once we have a 3D print or a wax pattern we can create a mold. There are several ways of creating a mold but the most common are rubber and metal molds. The mold will ensure the intricacies of your design are kept throughout the casting process.
Creating the Tree & the investment process
Using a proper jeweler’s centrifuge, the melted metal is poured into the mold being evenly distributed. The centrifuge helps create the inertia which is necessary for molding. After the burning out process, a swing arm with a cradle carries the flask in direct alignment with a container which will be used for holding the poured material. While the arm is in a crooked position, the container will be heated to melt the metal, the temperatures and the method used depend on the technicality of the equipment and the type of metal. Once the metal is at the desired temperature, the centrifuge is released, slinging the metal at high a speed from the container to fill the flack before it comes to rest.
Another method to cast jewelry very similar to centrifuge casting is vacuum casting. Melted material is poured with enough force into a flask for it to funnel through minute, intricate, cavities before it cools. It is also possible to cast jewelry without a centrifuge by simply pouring the melted material into the mold using a metal-specific syringe as a pump. Once the metal has been poured, it is allowed to cool down for a few minutes before being dunked into cold water to retain its final shape. The amount of time required for the cooling process depends on the type of metal that is being used and its melting point.
Buff and Polish
Next, the jewelry is given its final look by using a buffing wheel to give the piece a shiny, complete finish. Buffing machines, enamel clothes, polishes and filers can be used to the give the final piece the desired shape and style. If the piece has stones this is when they will be set.
