Your problem is designed to the casting industry. u003Cbr> u003Cbr> I generally talk about the basic principles, make molds according to what you want to do, and then use the mold to make molds (professional called casting), pour the metal into the mold, cool down, cool down Remove the excess metal later, and then polish and modify what you want. u003Cbr> u003Cbr> If you are making silver rings and other things, and it is made of small batches, you can buy a small pyramid electric furnace for melting metal. What is the electric furnace? I will not explain it in detail. If you plan to invest in small, use fire to burn it yourself, but this is very troublesome, because the melting point of the silver is 960 degrees, which means that if you want to turn the silver metal into a liquid, you need to use fire to increase the temperature to more than 960 degrees above 960 degrees. It is possible, so it is very troublesome. u003Cbr> u003Cbr> Then you need to make molds according to what you want to do. This is very important. If the mold is done, there is something wrong with you. Mold production is a deep topic. You have to make different molds according to your casting method (many casting methods, sand casting, loss of wax casting, die casting, etc.). This involves how to pour the metal liquid in, and determine the different contraction ratio according to the incompatibility of the metal, and how convenient it is to clean up after you cool it. The general molds are made by special companies or individuals. If you plan to do it, you plan to do it. You have to contact the mold. The other is the design. Do you want to cast it yourself? If you have no drawings or ideas, no one will make a mold for you. u003Cbr> u003Cbr> When these are all prepared, you can do it. During the process of doing it, you must also configure the spoon (used in inverted metal liquid), sand wheels, sandpaper, hand rubbing (polished correction) In addition, the important one is the problem of polishing, because the things you do are dim and will not be shiny to you. This polishing problem requires you to buy the polishing machine and other equipment. What is polishing? Check it on the Internet yourself. u003Cbr> u003Cbr> Almost, you ask how long you can learn, I really can't answer this, it is related to you. The intentional people quickly learned, and the time of impetuous people will grow a little. u003Cbr> u003Cbr> Your idea is a small and small thing in the casting industry. If you like this line, find a casting factory to study, huh u003Cbr> u003Cbr > OK good luck
