Oyster Shell Wholesale Charm, 925 Sterling Silver, 20mm x 10mm, Permanent Bulk Jewelry Making Charms

At HarperCrown we use jewelry casting which is an art that has been long used for thousands of years. With improvements in technology and the advent of superb tools and machinery, jewelry casting is an art that is more dynamic today than ever. This is how we create one of a kind pieces with the highest quality. 

Also called wax casting, we use a wax pattern that is made into a jewelry mold for being filled with molten silver or metal to create an intricate piece of jewelry.

The process involves 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.

Creating the Mold

Creating the Tree & the investment process

Once we have the mold we will "shoot" wax into the mold. This will create the tree which will placed into an investment.  Once the investment material has settled, the flask will be then placed into a burning kiln which helps burn away the wax leaving behind a cavity that works as the final mold for the jewelry piece. The wax melts out through a couple of “sprues” that are attached to the bottom of the mold before placing it in the kiln. The number of sprues depend on the size of the piece of jewelry. This is also called the burn out cycle in which wax models are connected to each other using a sprue forming a tree-like formation. This formation is then put into a metal flask which is filled with a slurry of plaster. The flask is then “debubblized” to get rid of any air bubbles or air pockets in the mold. Once the wax has melted away and the mold has been invested leaving behind no remaining wax residue and only a hollow impression to serve as a mold for jewelry, it is time to pour the metal of your choice.

Casting jewelry     

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.      

Plating         

All of our products are hand inspected for any imperfections. This is to ensure we give our customers our best work.  Once the pieces pass our inspection the pieces are ready to ship.
