What steps does jewelry processing generally go through?

Jewelry processing can be roughly divided into two types, one is gem processing, that is, cutting, prefabricating, grinding, polishing and drilling of gems; The other is finished product processing, which is the finished jewelry we usually see in jewelry stores. The production process of these jewelry is the jewelry processing steps, including: carving wax (computer printing also includes CAD drawing and wax spraying), waxing, mold reversal, mold holding, polishing, inlaying, electroplating, QC and shipment.

Cutting, preforming, grinding, polishing and drilling.

Carving wax

Carving wax: When making a piece of jewelry for the first time, the general outline of the jewelry is carved by hand or machine with industrial wax, and the ring template is made with this wax. Now most of them have started printing on computers. The computer first draws a picture with a computer, then prints the shape of the computer picture with a machine, and finally gets an initial jewelry template.

wax

Waxing: it is to use the above-mentioned carved wax as a sample, press on the plastic film, and save the template of each piece of jewelry through the plastic film for later use. When it is used again, the film is taken and the wax melted at high temperature is injected into the film with a waxing machine to obtain the wax shape of the jewelry.

Inverted mold

Reverse mold: put the wax shape of jewelry pressed with adhesive film into the reverse mold chamber, put it into lime water for high-temperature calcination, and inject gold water. By melting wax and injecting gold water, the blank shape of metal jewelry can be obtained.

Hold the mold

Closing the mold: the initial shape of the finished jewelry is obtained by manually grinding and modifying the shape of the reverse mold blank.

shine

Polishing: polishing the shape of finished jewelry with a polishing machine at high speed to make the surface of jewelry smooth and shiny.

Polishing technology

mosaic

Gem setting: it is the process of setting gems on polished jewelry metal supports.

electroplate

Electroplating: Put the polished jewelry into a chemical solution containing precious metals such as platinum or rhodium to coat the jewelry surface with one or more layers of precious metals, so as to keep the jewelry surface smooth and shiny for a long time.

Electroplated platinum jewelry

quality control

QC: QC is to have a special person in charge to carry out strict and meticulous inspection on each piece of jewelry to prevent defective products.

The above is the processing flow of finished jewelry.

incision

Cutting: it is mainly to divide a large piece of material into specific sizes according to the different shapes and forms of gems.
