Making jewelry is not just kneading mud, take a look at how the jewelry you wear is made! Step 1: Design drawings The designer will first draw a sketch on paper to conceive a new work, and then use pencil and gouache to complete the design draft. This process can take as little as a few days and half a month, and as many as a few months before a style is finalized.
The second step: hand-carved wax version (computer CAD version) craftsmen refer to the design drawings to manually carve the wax version, which is the most demanding process in the jewelry manufacturing process. The wax version must be smooth and clean, and the structure of each part is reasonable. The position and size of the inlaid gemstones are accurate. (This process depends on the complexity, ranging from a day or two to a few days)
This is a delicate job. With the development of technology, there are fewer and fewer jewelry made by hand, and most of them are drawn by computer CAD software (see the picture below).
CAD computer drawing However, for some special-shaped or animal-shaped jewelry, a good master will still choose a good hand-carved wax version. After all, the carved things have feelings!
The third step: Invert the ancient lost wax casting method and make the wax mold into an 18K ring. If it is mass production, then the front wax plate will be made into a silver plate and pressed into a film, and the wax mold will be produced in batches! But for customization, only one piece is made for each item, so we go directly to the molding process and plant wax trees first. 1. Planting a wax tree Weld each wax ring individually to a wax stick by hand, and finally get a wax tree shaped like a big tree, ready for casting. 2. Filling gypsum Put the planted wax tree and the chassis together with a stainless steel cylinder, and slowly inject the corresponding weight of gypsum slurry along the inner wall of the steel cylinder. solidification.
3. Baking gypsum The gypsum mold is baked for dewaxing, drying and casting heat preservation.
4. Casting Take out the baked plaster mold and prepare the metal solution for casting at the same time. Inject the melted and prepared gold water from the nozzle.
5. Gypsum mold blasting and cleaning After casting, the plaster mold is in a high temperature state. After taking it out of the casting machine, let it stand naturally for 10-30 minutes, and then put it in cold water for blasting. After the gypsum burst due to shrinkage, take out the golden tree, brush off large pieces of gypsum with a steel brush, soak in 30% hydrofluoric acid for 10 minutes, clamp it out and rinse to remove the remaining gypsum until the surface of the golden tree is clean.
6. Cut the casting Cut the jewelry on the golden tree along the bottom of the nozzle to dry. Step 4: Molding and molding are all done by hand, using a special calender to push back and forth on the surface of the jewelry. This process requires certain skills and techniques.
Step 5: Matching stones According to the jewelry design drawing, manually sort the diamonds or gemstones, pick out the suitable color, cut, and size matching, and prepare for inlaying. Step 6: Setting the Gems Each diamond and gemstone is hand-set
Micro-setting, this is a technical job, setting gems under a magnifying glass dozens of times! Step 7: Polishing, electro-gold further polishes the metal surface and details, and some jewelry needs electro-gold treatment on the surface to make the surface smoother! Step 8: Quality inspection Check the finished jewelry, if it is unqualified, it will be returned to the previous process and re-made! After it is completed, it is then sent to a jewelry testing agency for an authentication certificate.
The above are just some important links in the production process of a piece of jewelry, and there are many processes that cannot be shown one by one. Doing jewelry customization is not just making mud, place an order today, and want to ship it tomorrow. The production of jewelry has to go through "seven seven forty-nine" processes! Wait patiently for a perfect work to come out!
