The whole process of processing a piece of silver jewelry

Every piece of jewellery is infused with soul by designers and manufacturers, and their birth requires very complicated process steps. Below we will introduce you the entire process of a silver ring from design to finished product. 1. Concept and design: The designer puts his own structure into every piece of jewellery by the designer and manufacturer, and their birth requires very complicated process steps. Below we will introduce you the entire process of a silver ring from design to finished product.　　　　 1. Concept and design: The designer draws a sketch of his own idea by hand, and then uses a drawing software to draw the sketch with precise dimensions on the computer to complete the initial design drawing.　　　　 2. Craftsman carving wax: The jewelry craftsman engraves the wax plate by hand according to the design drawings, and then uses the lost wax casting method to pour the silver plate, and the batch production of the wax plate requires the silver plate to press the rubber mold. This is the most demanding process in the jewelry making process. The silver plate made must be smooth and clean, with reasonable structure of each part, and the position and size of the inlaid gemstones are accurate.　　　　 3. Rubber mold wax injection: After the rubber mold is opened, perform wax injection operation. The wax in the wax injection machine should be kept between 70-75 degrees, the wax liquid is injected into the film, the wax mold is taken out after cooling, and repeated in order to obtain multiple wax molds.　　　　 4. Choose the matching stone: According to the silver plate and wax model, select the matching stone with the right size, shape and color.　　　　 5. Complete the wax pattern: prepare all the wax plates needed for this batch production.　　　　 6. Planting wax trees: each wax ring is individually welded to a wax stick by hand, and finally a wax tree shaped like a big tree is obtained, ready for casting. 7. Weigh the wax tree: weigh the rubber chassis before planting the wax tree, and then weigh the wax tree again after planting the wax tree. The weight of the wax tree can be obtained by subtracting the results of the two weighings. The weight of the wax tree is based on the silver The density ratio is converted to obtain the amount of metal to be cast. 8. Gypsum filling: Put the planted wax tree on the stainless steel tube together with the chassis, and slowly inject the corresponding weight of gypsum slurry along the inner wall of the steel tube, without the wax tree, naturally prevent 6-12 hours after vacuuming. The plaster solidified.　　　　 9. Baked gypsum: Baking plaster molds for dewaxing, drying and casting heat preservation.　　　　 10. Take out the plaster mold: Take out the baked plaster mold, and at the same time prepare the metal solution that needs to be cast.　　　　 11. Pouring liquid silver: Pour the already melted silver water into the nozzle.　　　　 12. Centrifugal process casting: use a vacuum induction centrifugal casting machine for casting.　　　　 13. Frying, washing and cleaning of plaster molds: The plaster molds after casting are in a high temperature state. After they are taken out of the casting machine, they will be left for 10-30 minutes, and then placed in cold water for frying. After the gypsum bursts due to shrinkage, take out the silver tree, brush off the large pieces of gypsum with a steel brush, soak it in 30% hydrofluoric acid for 10 minutes, and rinse after clamping to remove the remaining gypsum until the surface of the silver tree is clean.　　　　 14. Cut the casting: Cut the jewelry on the silver tree along the bottom of the nozzle and dry it.　　　　 15. Roller polishing process: Put stainless steel abrasive and active organic synthesis solution into the roller, and rub it with rotation to make the surface smooth and bright.　　　　 16. Calendering process: All calendering is done by hand, using a special calender knife to push back and forth on the surface of the jewelry. This process requires certain techniques and techniques.　　　　 17. Polishing process: Use a polishing machine to polish the jewelry until the surface is smooth and bright.　　　　 18. Quality control: finely inspect the finished jewelry one by one to ensure that the quality is qualified.　　 The above is the information about silver jewelry processing summarized by the author for you.
