First, the software controls a computer-operated milling machine. Milling machines put two pieces of aluminum metal into a two-part mold. They make a part with ring details, that is, all parts except the base. Lubricating oil will constantly wash away the metal carved by the machine, and the mold will complete the complex design details of the ring bit by bit. After carving, the craftsman will coat the cavity with a layer of powder to prevent the wax to be injected next from sticking to it, and then fix the mold on the injection device, which will inject hot wax liquid at high pressure to fill every tiny corner and gap in the cavity engraved with many details, and the wax film can be taken out in a few seconds. The model in front of us is a beautifully designed interface of a champion ring. Craftsmen will use elastic rubber molds, because if metal films are used, it is difficult to take out the three-dimensional finished products, and then cast wax in a low-pressure furnace, because rubber films cannot withstand high-pressure injection. Moreover, the dielectric base has no delicate details and does not need high pressure.

The second and next step is to assemble the wax mill of the two parts of the ring, and stick the wax together with a pointed soldering iron. At this stage of production, the ring will be adjusted to a customized size. The craftsman can make the ring smaller by cutting off a part of the outer diameter of the ring, or make the ring larger by filling the outer diameter. Then the craftsman will make a wax structure and put it on it. They are going to throw several wax slices at the same time. They welded a small rib on each mold, and then connected each rib to a thick wax rod. After this step, a tree-like branch structure appears, and all wax films are fixed on it. Then the craftsman welded the structure on a rubber base and put a thin metal net on it. Then the craftsman will mix some gypsum and stir it for half an hour. All bubbles will be removed by vacuum cleaner, and then the stirred gypsum will be injected into the bacteria bottle, surrounding the wax film and supporting structure inside. After 12 hour, gypsum will harden and form a shell around the wax film, and then put it in the oven for 12 hour, and the wax inside will melt, leaving an empty shell in the shape of the wax film.

Third, we only need to melt some metal now. Ping finally reversed the technique of using wax as a mold, which is called paraffin casting. Then the craftsman pours the molten gold into the gypsum shell, and the gold will flow into the groove and enter the cavity left by the molten wax. When the cooled solid shell is put into cold water, the hot gypsum will dissolve immediately, leaving the casting. The model that used to be made of wax has now become a gold replica. Next, cut off the ring-making part from the supporting structure, and then the craftsman needs to grind off the excess residue. Next, the inner surface of the ring is polished with a thin polishing tool. In order to polish the outer surface of the ring more smoothly, craftsmen will use grinding wheels to process it. There are several openings on the grinding wheel of the grinding wheel, which will produce a perspective effect when the grinding wheel rotates. Now the whole surface of the ring has been polished and can be polished.

Fourth, apply some polishing compound to the ring, and then polish the ring with another wheel with an opening. Next, the interface part will be sent to the gemstone setting department, and the technician will polish the outline of each setting hole with a fine rotating tool to load the pointed gemstone setting at the bottom. Then the technician will set each gem. The four claws around pressed against the edge of the gem. Next, the technician will set diamonds. He pressed every diamond in, then pressed the surrounding metal inward to fix the diamond below, so that the surface of the ring was completed. Then the craftsman needs to weld it on the base, spray a thin layer of black paint on the ring surface with a spray gun after welding, and then wipe off the residue, which will leave a black background and highlight the details on the ring. Some rings need to be decorated with a hair salon. Hair salons are actually liquid glass, which can be painted like paint and baked in the oven for 30 minutes. Finally, the factory will test a name or other representative information on the surface of the medium or in class with a computer-controlled engraving machine according to the requirements of customers.
