PRODUCTION PROCESS INTRODUCTION
How to make a perfect jewelry? It will must need the good design from customers. When the clients have a idea and after discussion with ours workers, the designer will make a drawing design for workshop and send the clients for checking, modification and confirmation.When the designer makes a 3D drawing, we will use the 3D printer to turn the design on the drawing into a real jewelry, and then use the jewelry as a model, and put it into the machine that produces the mold to start the mass production of jewelry.
In the first step, we will cut a piece of film about 5-7cm, which is usually made of rubber imported from abroad, which has good ductility and is not easy to deform, which is beneficial to the wax mold in the second step to protection.
In the second step, the template made by 3D printing technology is put into the plastic film, and the model of the jewelry is pressed out.
Third, through high-temperature wax injection, the melted wax is injected into the film in the form of liquid. After the wax is dry, we will get a wax-shaped jewelry that is exactly the same as the jewelry.
Fourth, it will be handmade by workers, and 150-200 wax molds will be glued together at high temperature. This process is very important and especially tests the skills of workers. If there is a mistake, a lot of materials will be wasted.
Fifth, there is a design with zircon, which will be hand-set by workers on the wax mold.
Sixth, inject the planted wax tree into the gypsum. The proportion of gypsum is very important. The proper cement will ensure that the surface of the jewelry is smooth after production.
Seventh, after the plaster is solidified, put it in an oven with a high temperature of more than 800°. Under the high temperature, the wax mold will completely melt, and the complete jewelry outline will remain in the plaster.
Eighth, sterling silver or copper and other metals are dissolved into a liquid at high temperature. During this process, a sanitary environment must be ensured. If a lot of impurities enter the metal liquid, the quality of the jewelry will be deteriorated.
Ninth, pour the dissolved metal liquid into the plaster and let it fully enter the outline of the jewelry.
Tenth, after the metal liquid cools, break the plaster, rinse, we will get the complete jewelry.
Eleventh, the obtained jewelry is polished by hand, usually we use a large specialized machine for polishing, and then perform delicate polishing by manual hand to ensure that every angle of the jewelry is flawless.
Finally, our polished jewelry is electroplated, and the surface is plated with a layer of pure gold, showing the color that the customer likes. After being beautifully packaged by our workers, they will be delivered to customers.
