Gold or jewelry casting process is defined as the process by which a wax pattern is converted into a jewelry mold and then filled with molten metal or gold to create a custom piece of jewelry.

Initially, each wax model has a rod escorted arm, which is basically a wax stick. This rod is used to connect wax patterns to a “tree” of wax. Each model is welded to the stick, to form a branching tree, once the tree is completed and all models are attached, Jewelry with wax is placed in a metal cylinder known as the vial so that plaster can be poured into it to create the molds, as this whole process is called “missing wax casting”, after that, the wax vials are placed in a very hot oven for a period of six or eight hours until they are picked up Details of cutting the wax into the mold when absorbing the wax.
- Gold casting process steps
All jewelry that is manufactured begins as a wax model. This mold is made using a cylinder with smell cavities inside which plaster is poured into it.
Once the mold is prepared, put it in the oven until the plaster hardens and all the wax surrounding the main cavity is melted.
Next, the jewelry designer uses a wax-free mold, by pouring gold, or molten metal into the mold cavity with a vacuum machine, or centrifugal casting machine
After a few minutes, the jewelry designer will throw the mold in a bucket of cold water to disperse it, and access the jewelry piece which is the exact replica of the initial wax pattern.
