jewelry factory:Production of jewelry
There are two types of casting machines, jewelry casting machines and vacuum centrifugal casting machine. The cast crank is rotated to move the force to push the molten metal into a mold. Vacuum machine vacuum casting and gravity to draw the metal into the mold cavity.
Each machine includes a mold. A small container containing the molten metal. It can withstand high temperatures. It has a hole at one end of the metal balls that are packaged in a crucible to melt with a light spray of metal can be dissolved in another. The graphite crucible which is heated by electricity. Allows you to control the temperature with a thermometer to measure the height. For more complex than I have to use the induction furnace with a high frequency alternating electrical current to cause the melting rapidly.
Casting for the cast. Bao will be removed from the oven and placed horizontally in the machine. The crucible is positioned in alignment with the socket. I cast the molten metal in the crucible. And look up to when the metal is melted until the time is right then I start up, leaving the socket has been moved by the centrifugal force of the machine. Driving force caused by the centrifugal force that pushes the metal into the mold cavity.
For the vacuum casting machine. Bao will be removed from the oven and placed in a mold with the top opening. Metal will be melted in a crucible and then flows into the open mold. At the same time I worked in a vacuum system. This will pump the air from the mold and the molten metal is then sucked into the mold cavity.
Unit 8, after the fusion process. After the merger was completed. Bao will be moved to the next. Plaster cast was made of gold will be dissolved by the light and put in a bucket of cold water. I cast a plaster cast, which moved to be together in a solid cast with a brush and water or water pressure to normal levels.
Piece of molding will be cut by a cutter (Cutter Sprue) to separate parts of the plant or its base (Base Sprue) and then cleaned with acid to remove oxide or any other material that is coated with cement. thrown away.
Finally, the sample will be checked carefully. To see how each piece is added to fill or not. (See all areas of the ring and the angle between the skin and is complete), ie the metal is hardened by a small hole, which will result in surface damage (also known as pores).
When I asked the question about the casting porosity. This will affect the style of the piece. And how this problem can be reduced as the pore is indicative of small holes on the metal surface. This is a signal that indicates cast destroyed. Porous surface can be lost in some of the season against a small hole, however, often find that these pores. Appears in all metal.
The pore is the result of many causes. Sometimes you are on the steps of the process (air bubbles, cracks in the plaster cast of gold, the contamination of grain, metal, or melt metal cools too slowly, while casting) and other causes were. In the formation process of the piece. (Spark plug wire, that is not appropriate, the design of a candle to the complex, which can not be applied in practice in the design or production process, which is a space the width of the ring is in contact with an area of ​​narrow that impede the flow of metal).
Unit 9, cleaning and assembly. In those parts of the group. Computer technicians will be part of the stem is cut off the excess of the underlying metal is still holding a piece of polished stone grinding wheel of the artisans will clean the surface with the same type. But contrary to the brush head rotates. Casting is not complete may be solved with a little 'editing to refine and polish the paper.
Before the ring. Components must be polished before. The contact area with the rest of them will be difficult for your body after assembled.
Horizontal tanks are not used in the polishing surface is not complete. The rotation of the drum parts are polished to a smooth surface and a sleek metal. This will reduce the time to polish by hand on it.
This gem is ready to enter the assembly process. The technician will need to use stone wheels grinding, polishing, welding equipment and tools designed to produce different types of jewelry. Parts or components of the ring, which is not primarily an information that the merger process. It will be a part of this process.
Learn the basic problems that arise. And learn about the various forms of design, including methods that are effective with your work. This process will be a good idea and easy to fit the pieces together.
Units 10 and buried at this stage is decorated with precious stones embedded on the surface or the rings. And 'rooted in any form. The metal around the stone tablets, stones must be taken to protect them. Ring with a good design will have to think in terms of the gemstone in a solid. Including the ability to represent the beauty of the stone to be adorned with beads. It works through a with or without motors, which are integrated into work. This tool has a motor that can be attributed to the drill head in a different season for the rasp. If it is buried in a corner. Every corner must contain enough metal to make it a place can be supported by-product corn. To refine and improve the area around the grain product.
When I asked to put the gems buried in each step and make comments. It led to embed a piece, which uses a different technique to make an example of Pave 'or built into the bridge. Try to find out what are the disadvantages of the model, which can cause problems in the process of embedding it. As you learn more about the technique of embedding and embedded design. Will result in the design can be put into practice even more.
That the wheel can be used as material for paper, metal or any other I do not follow the order of your body. Starting from the rough and polished until the author has a high gloss. The use of different wheels with polished metal. Contrary to compose a piece of jewelry in the last step requires the talents of technical polish. It is not good to be familiar with the tricks of the trade body composed of different metal paint, sanding, and Silver, Gold, jewelry rhodium plating, which has a high value and fragile, like emeralds, pearls can be damaged by. Contrary to some. The entire polishing process. This includes the ultra-sonic cleaning machine that uses steam I have to be careful to keep any gems of knowledge necessary for proper maintenance.
Sakson on surfaces difficult to access. Must use a special process, so you know what the project may not have adequate coverage to the contrary, with the result that production costs increase. We should talk about the design that helps prevent these problems
