The Jewelry manufaturing
Our master model makers are highly experienced craftsmen, that create from the design the first prototype that will be used to create a high quality final product.
Our master makers have been trained to the highest standard of the jewelry industry , and are familiar with all techniques of jewelry production.
We can make a master by hand, in wax or in a 3D file that will use the computer generated model using a 3D printer.
Once the master model has been created and inspected for any flaws or problems that could affect the production process, the master is molded.
This process involves to make a rubber mold by positioning the model between layers of rubber and is vulcanized to the point until the rubber forms an impression of the master.
Once this is completed, a skilled craftsman is separating the mold from the master model by cutting the rubber with a surgical knife.
After the model is removed, there will be an impression of the master that will be injected with wax.
After the master mold has been inspected for any flaws or imperfections, it is now ready to inject wax to create an exact copy of the original master.
This process is done by injecting liquid wax into the mold by a wax injector unit.
The wax ... is filled by pressure and it pushes the liquid was into the mold.
Once the wax has been cooled, the mold is opened and the wax can be removed.
Now the wax is ready for the casting process. The wax model is now positioned on a wax stem called a tree, this way several pieces can cast at the same time. The wax tree will be covered by a metal cylinder and then filled with plaster that has been mixed with water. Once the plaster is hardened, it will be places in a burnout oven to remove the wax impression from the plaster mold.
Now the plaster mold is ready for casting, this process involves to shoot the liquid gold through vacuum pressure in the cavity of the plaster mold and so, reproducing the master
Once the metal is cooled, it can be removed from the plaster mold and is now ready for production.
Each piece is quality controlled for any defects before it goes to the next step: the filing step
The casted piece has to be cleaned and prepared by skilled craftsmen. This involves filing, grinding and preparing it for the polishing process.
Again, the piece is inspected to any flaws and imperfections which is a very important step to ensure the high quality.
It is now ready for the pre-polishing process. our polishers have been trained to achieve very high quality so that the item is ready for the setting of the gemstones.
Once again, it passes through a rigorous quality inspection.
