Production process: beer wax mold → seed wax tree → filling powder impression → powdering → ingredients → mold → roller polishing → die → fried gold → grinding machine polishing → inlay → edge → sanding → electricity gold → QC ( Detection) → Finished product storage. 1. Beer wax mold: According to the specifications and specifications of the customers, the wax in the waxing machine is poured into the plastic mold (mold), and the beer is made into a wax mold that meets the requirements. 2. Kind of wax tree: solder the wax mold to the wax rod (commonly known as tree bar). 3. Filling the impression: Put the welded wax mold tree into the steel cylinder, pour the gypsum powder (commonly called powder injection), and use the vacuum machine to remove the air bubbles in the powder to prevent the platinum jewelry from being cast. There are trachoma (small holes). 4. Powdering: Put the powdered wax tree together with the steel cylinder into the electric oven to heat the wax (high temperature volatilization) so that the powder temperature reaches the platinum mold temperature (about 950 °C), which takes about 10 hours. 5. Ingredient melting gold: The platinum material is added in proportion to palladium and platinum (an alloy material used for platinum jewelry) to form a PT900 material (ie, platinum with a purity of 90%). If the imported PT900 raw material can be directly smelted into a suitable piece of processing jewelry (ingredient parts). 6. Inverting the mold: Put the PT900 material into the vacuum suction mold or centrifugal mold machine according to the weight required for each workpiece. After melting at 1770 °C, the powder will be filled with powder. The workpiece in the crucible is thrown into the mold-cutting machine, and the mold-cutting machine injects the platinum liquid into the workpiece in the crucible and molds it into a desired platinum blank. 7. Barrel polishing: The gold plate that has been inverted is polished by a roller machine to express a certain brightness. 8. Jewelry model: The empty gold plate that has been polished by the drum is trimmed according to the requirements, such as smashing, holding, hammering, and other processes. The deformation and surface roughness of the empty gold tray are trimmed to make it smooth and free of trachoma (small hole). 9. Blasting gold and grinding machine polishing: The corrosive substances on the surface of the empty gold tray are removed by the corrosive action of some chemical raw materials (potassium cyanide, etc.), and polished by a magnetic grinder. 10, inlaid stone: the style required to be equipped with the required inlaid raw materials (ie stone) inlaid on the empty gold support that has been subjected to the gold frying process (carriage, rockfall according to the shape and size of the stone, and stone inlay according to different inlays stable). The stones to be inlaid should be flush, the stone and the inlay should be matched, and the stone and the stone should have a reasonable distance; the inlaid claws should be symmetrical, the inlaid nails should be smooth, and the inlaid gold edges should be thick and neat. 11. Jewelry: The edges and claws of the semi-finished stone have been trimmed for sanding. 12. Grinding: The semi-finished products that have been finished with the inlay and the edge-finishing process are thoroughly polished by a flying saucer or a sanding machine with a wax (shaving wax) or a yellow and white cloth, a large and small brush, and a needle-spinning rod. 13. Electric gold: Platinum water (including “ 铑 †element) is used to plate the surface of the jewelry to make the surface of the jewelry whiter (white) and brighter. Platinum jewelry inlay loss link and cause items: molten gold, mold, die, gold, stone, edge, polished; total loss rate: 0.25, 0.7, 3.2, 0.7, 1.3, 1.3, 4.55, 12. Reason for loss: 1. Ingredient melting gold: In the process of platinum becoming Pt900, the platinum and the filler are oxidized and volatilized in a high temperature state, thus causing the loss of the process. 2, the mold: This process is a process of smelting Pt900 into a single piece at a high temperature by a centrifugal mold machine, a small amount of oxidized and volatilized, in addition, a small amount of Pt900 material adheres to the vessel after melting, resulting in loss. 3. Model: This process is to process and trim the platinum empty tray after the mold is turned off. The dust generated in the process of smashing, sandpaper grinding, plastic car and other processes disappears in the air and is partially absorbed by the human body. Recycling, causing losses. 4. Frying gold: the loss caused by the melting of some platinum in water during the gold-filling process using chemical raw materials. 5, inlaid stone; in this process, a variety of tools are required for the parking space and the use of sandpaper and other grinding claws to make the platinum inlaid stone position and other parts smooth, but also cause partial loss. 6, the edge: the semi-finished inlay and the shortcomings left by all the previous processes (such as the edge is not straight, the platinum surface is too thick, etc.) to trim, causing partial loss. 7. Grinding: Therefore, the process must use the yellow cloth 粗 (rough cloth) and white cloth 幼 (young cloth) to thoroughly polish the surface of the semi-finished product by high-speed electric grinder, and use electric grinder, wool bat, flying saucer and other tools to grind the electric grinder. The corners of the jewelry are also completely polished by the machine, so the loss of this process is high.
