How to quickly make cast copper template

The production of copper sculpture casting method

1, muddy casting method of copper sculpture casting process: before the Shang Dynasty copper sculpture casting process are muddy casting method, that is, a one-time casting molding. The method is divided into three aspects: alloy, casting, the system model.

(1) alloy is made according to the needs of the bronze artifacts will be copper and tin according to a certain ratio together, in the melting furnace heated and melted into a bronze solution, can be used for casting. Alloy different ratios for what kind of bronze is different, such as the ratio of the Yue Wang Goujian sword, copper is 80%, tin accounted for 20%.

(2) casting, will be injected into the bronze solution from the gate in the Hop Fan, copper cooling, remove the inner and outer Fan, and then polished and trimmed, that is completed.

(3) making the model is to make the pottery model. The first copper carving mold, that is, the first clay to make a model of the same size as the copper carving will be cast, decorations and inscriptions should also be engraved on it at the same time, and then drying, baking to make it hard. Then turn the outer model, water and fine yarn, soil and chopped plant stems into a slurry, smeared in the clay mold, to be half-dry slurry, after the knife divided into several pieces to remove, dry and then baked hard, it becomes the outer model. The production of the inner model is made of clay according to the shape of the clay mold minus the thickness of the wall, the inner wall, such as inscriptions, but also need to inscribe the inscription on the surface of the inner model. After drying and baking hard, the inner fan and outer fan assembled together, tied with a rope fixed, and then wrapped in thick clay, leaving the pouring of copper liquid pouring mouth and discharge the air inside the fan of the aperture, at this time between the inner and outer fan of the space between the shape of the casting of copper sculpture.

2, the Shang Dynasty sub-casting process decoration: that is, the bronze sculpture body and accessories casting, sub-casting method and sub-casting method and after casting method.

3, lost wax method and welding method: after the spring and autumn, there are two new casting process: lost wax method and welding method. Lost wax method, also known as the melting mold method, the first production of wax bronze sculpture object model, and then dip coated with special mud to become a mud mold, drying and baking, so that the wax melted out and become a tool model, and then pouring bronze liquid into. Such as Hubei Suixian Zenghouyi Tomb unearthed copper plate, Henan Xichuan under the temple unearthed copper carving ancient forbidden, etc., beautifully modeled, decorated and elaborate, breathtaking.

Spring and Autumn period began to popularize the welding technology, from the development of the casting method, that is, the bronze sculpture of the parts of the casting and then welded, generally have copper welding, tin welding, lead and tin alloy and other solders. Such as Hebei Pingshan Zhongshan King's Tomb unearthed the dragon and phoenix program, that is, using a variety of solder.

4, wrong gold and silver, gold and silver, gilt, engraved burin and other new decorative techniques: spring and autumn in addition to the two casting process, there are wrong gold and silver, gold and silver, gilt, engraved burin and other new decorative techniques. Wrong gold and silver method for: in the copper carving objects cast hook groove, and then burin, and then the heated gold or silver wire hammered or squeezed into the groove, and then polished. Such as the famous ejunqi section on the inscription, or the Yue Wang Goujian sword, Wu Wang Fuchai spear, Luanshu fou, Henan huixian unearthed horse head yamen decorations, are the fine art of this process.

Bronze sculpture weapon casting technology is particularly noteworthy, the Spring and Autumn period, infantry combat more than the car battle, to close combat, a class of swords and knives of short weapons more practical. Sword is the most common weapons during the Spring and Autumn and Warring States period, and the most refined sword of Wu and Yue, which was famous all over the world at that time.
