Manual processing
Filament craft
The filament process refers to the fine gold process of making a shape by means of a metal filament through a twist, a silk flower, a silk, and a pile. At the time of production, the metal such as gold or silver is first drawn into the desired thickness, and then the drawn strands are twisted (in the industry, the silk thread is called), and the maker uses the tweezers to make the silk into various patterns according to the pattern of the drawing. The parts of each shape are twisted together, and the solder powder is sprinkled over the fire, that is, welded to form a certain overall shape. This overall shape is called "black tire", the black tire is cleaned by dilute acid, and it needs to be processed after silver, blue, gold or silver, and then become a finished product. The filigree jewelry is slender, delicate, rich in connotation, and the myopia effect is excellent.
2. Machine processing technology
(1) lost wax casting process
Lost wax casting is one of the main production processes in the jewellery industry today. The lost wax casting jewelry has become the mainstream product of today's jewelry. The pouring process is suitable for embossed embossed shapes and can be produced in large quantities.
The process of losing wax casting process is: making metal model - pressing plastic mold - waxing mold - planting wax tree - pouring plaster mold - casting casting.
(2) Stamping process
The stamping process, also known as die punching and embossing, is a embossed pattern manufacturing process. The steps are as follows: firstly, a mold is made according to a master mold, and then an embossed pattern is formed on the metal by pressure. Stamping process: embossing patterns, forming (bending), joining the joints (usually with solder).
The stamping process is suitable for ornaments with concave and convex surfaces on the bottom surface, such as small locking pieces, or items that are not obvious in undulation and easy to be formed by two-step or multi-step stamping or combination. In addition, the extremely thin parts and the jewelry that requires delicate detailed patterns are also needed. Stamping process.
(3) Machine chain processing technology
The machine chain processing technology refers to a method of processing chain jewelry by machinery. Common venetian chains, bead chains, and striated chains are machined.
The main process flow of the chain processing is: drawing - chain - welding - surface treatment - assembly - cleaning.
The characteristics of the chain process are large processing batch, high efficiency, many styles and good quality. Necklace jewelry in the market today is almost occupied by mechanical necklaces.
3. Surface treatment process of precious metal jewelry
Precious metal jewellery is surface treated in the later stages of its production to achieve the desired artistic effect. There are many methods for surface treatment, including: engraving, gold plating, electroplating, car flowering (milling), sandblasting, etc.
(1) Electroplating process
The electroplating process is a processing method for surface coating of precious metal jewelry, such as gold plating of silver jewelry, rhodium plating of platinum jewelry, and the like. The main process of the jewelry plating processing method is: acid-base washing - degreasing and polishing - electroplating. The electroplating process protects the surface color and brightness of precious metal jewellery, giving the jewellery a more beautiful appearance.
(2) gold-plated process
The gold-plated process envelops the extremely thin gold foil layer on a non-golden ornament, then warms it, and uses a tool to firmly press the gold foil against the surface of the ornament without leaving a seam. Gold jewelry looks like gold jewelry. The gold-plated process is also a common jewellery surface treatment.
(3) engraving process
The engraving process is a process of using a trowel to create a pattern on a precious metal surface with a hammer and a hammer. The ornamentation can be deep and shallow, uneven and undulating.
(4) Car flower (milling flower)
The process of carving the surface of the ornament with the high-speed rotating diamond cutter and marking the shiny horizontal and vertical stripes and arranging the pattern is called car flower or milled flower. Because the diamond milling cutter is very hard, the streaks that are milled out are smooth and flashing. Everyone calls the flash ring or the flashing pendant, which is processed by the car flower process and is very popular among people.
(5) Sandblasting
Fine quartz sand is sprayed onto the exposed polished metal surface with high pressure, resulting in a soft surface finish.
