(1) Pre-preparation: After obtaining a complete jewelry design pattern, the processor should first read it to understand the design intention of the jewelry designer and analyze the overall structure of the jewelry and the setting method of the diamond. On this basis, prepare processing materials and adjust processing equipment.
(2) Piece-by-piece processing: according to the results of structural analysis and the principle of taking the greatest priority, the whole jewelry is decomposed into several independent parts, and then metal materials are prepared according to the weight, thickness, width, thickness and length of each part, and pressed, laminated, stretched, cut and plated with tools such as tablet press, wire drawing machine, nest anvil, pit iron, golden hammer and scissors. As well as tools such as files and pliers. To set diamond jewelry, we must first process the setting of the main stone and the auxiliary stone.
(3) Assembly and molding: according to the design pattern, put the processed scattered components on the cement, and pay attention to the overall coordination and high and low levels, which is very important for the perfect expression of design requirements. After the whole arrangement, the gypsum slurry prepared in advance is poured on the jewelry prototype bonded with rubber. When the plaster dries, remove the plasticine, and then the whole front of the jewelry will be firmly shaped by the plaster.
(4) Integral welding: firstly, clean up the welding spots on the jewelry surface on the gypsum base, prepare several metals for welding from high temperature to low temperature, use borax as flux, and use the welding tool of balloon-oil pot-fire blowing structure to weld in turn according to the order of first big and then small. After welding, the gypsum powder of the jewelry blank is cleaned, and the small parts are welded with low temperature metal. Pay attention to check whether the solder joint is real, try to complete the welding in a short time and keep the solder joint clean.
(5) Fine treatment: Although the jewelry after welding is basically formed, it is quite rough, so it needs to be finely polished with tools such as file, sandpaper, paper and leather grinding wheel to remove all redundant welding and file marks. If there are sand holes that cannot be filed, they need to be repaired by fire welding. When doing this process, it must be fast and accurate to avoid the original solder joint falling off.
(6) Diamond inlay: Diamond is the center of the whole diamond jewelry, so the whole process from design to processing should put diamond inlay in the first place. First of all, choose an appropriate setting method, and use tools such as crane, fine file, pliers, tweezers and wood clips to complete the diamond setting process through gem observation, gem placement, setting position and gem reinforcement. When inlaying, usually put the auxiliary stone first, then put the main stone, and then grind the melon with beads or polish the edge with rubber wheels.
(7) Polishing and cleaning: Polishing is to improve the smoothness of the metal surface. Commonly used tools are sander, brush, green wax yellow cloth wheel and red wax white cloth wheel.
(8) Post-treatment: When diamond jewelry is processed, the non-ferrous metal layer (such as electroplating 18K platinum, etc.). ) is often added to the metal part of diamond jewelry to achieve novel artistic effects. In addition, as an industrial product, the factory logo, metal purity, diamond weight and other parameters must be printed on diamond jewelry before leaving the factory, so as to complete the whole diamond jewelry production process.
