Gold Casting Process of Jewellery Making Step 1 This is the mould which has a cavity in the shape of the desired final jewellery design Step 2 Liquid hot wax is injected into the mould which then cools down and settles some time later
Next, this gold cup has to be fitted into the band to form part of the final ring. A jewelers saw is used to create a wedge in the band where the cup will be fixed. The cup is then aligned with the band and the two are soldered together using small specks of gold as filling.
Jewelry manufacturing begins with the model. There are 2 main ways to build a model. By Hand Skilled craftsmen either carve a design out of wax, or craft different elements of metal together to create a master model. By Computer Computer designers utilize special programs to build images that create the tiniest details. CAM Computer designers utilize special programs to build images that create the tiniest details.

Once you have a model, a mold is made. A mold enables you to duplicate the model as many times as you would like in any metal. Hot wax under pressure is injected into the mold and removed when cooled, which serves as a casting model. Waxes are grouped together on a wax tree with other styles to be casted in the same metal and color. The wax tree goes into a form, where plaster is poured into it. The form is baked overnight and the wax is melted away. This leaves an empty cavity of the rings. Metal is heated to extreme temperatures and transformed to liquid. The metal is vacuumed into the plaster form with the now empty cavity of rings.
When a ring style is ordered, different metal components are ordered to the specifications of the desired ring. Those components are pieced together and cut to size. We either solder or laser the metal to weld it to accommodate the proper center stone and finger size. Since platinum requires such high heat, it is always welded by laser. Next, the rings go through a series of polishing stages to prepare them for stone setting. Diamonds and gem stones are picked to the specifications of the style, accurate to the .01mm. Color, clarity, and cut of each accenting diamond or gem stone is double checked. Using special drill heads in the actual shape of diamonds, bearings are cut in the metal. Each stone is set into its bearing and secured by the surrounding metal. There are several different methods to securing stones to jewelry.
Once the ring is assembled and stones are set, it39;s time to finish the piece. Using different sized and shaped buffs and polishing brushes, we are able to access every part of the jewelry from inside to underneath the gallery. The final polishing step is called lapping. Lapping ensures the ring have a smooth, high quality finish. Since white gold is not pure white, it requires plating. We plate our jewelry by attaching electrodes, then dipping in rhodium solution. Rhodium is a pure white metal.
After your jewelry passes through the design and casting stage, the final fabrication can take anywhere from 3 days to 3 weeks. At this point the jeweler refines the main structure of your ring, necklace or other piece. The jeweler files down the casting skin to reveal the metal underneath.
The gold casting process involves the following steps: Wax model and casting preparation. Using the design, a wax model is carved or printed to represent what the finished piece will look like in three dimensions. These are connected to a wax stem by a sprue.
