The plaster for the lost wax method is

Lime triad and charcoal clay.

Molding is done in ground pits, the molding material being prepared from wax and tallow, and the molding material from lime tritter and charcoal clay, the ratio of wax to copper used being one to ten. The liquid metal is poured through the channel. For large quantities of devices, in order to improve work efficiency, the wax pieces were first embossed with patterns on the sample plate, and then spliced into a mold. Xuande Ding Yi spectrum" in the Ming dynasty cast Xuande furnace with yellow wax for mold blank.

Some tripods and furnaces need large quantities, when this method has been applied. A large number of historical facts show that the lost wax method in China continues to apply to modern times, widely spread in Beijing, Shanxi, Inner Mongolia, Jiangsu, Guangdong, Yunnan, Qinghai, Tibet and other provinces and regions, Foshan, Suzhou and other places are still using the above traditional techniques to produce art castings.

Expanded Information

The wax will be made into the style of the type of ware to be produced, and then the high-temperature-resistant fine mud slurry dripping to the surface of the wax model, and sprinkle fine yarn in the mud layer, repeated many times, so that the formation of a complete type shell, dry and warm the wax melted to form the type of cavity, used to pour the copper solution (i.e.: copper plus lead, zinc, tin and other metal elements of the solution). ). After the completion of casting, after the shell, polishing, old, a beautiful and exquisite antique bronze will be displayed in front of you.

Lost wax method precision casting called investment casting, is a kind of less cutting or no cutting precision casting process, is an excellent process technology in the precision casting industry, its application is very wide.

It is not only suitable for various types, various alloys of precision casting, and the production of casting dimensional accuracy, surface quality than other precision casting methods to be higher, and even other precision casting methods are difficult to cast the complexity of the casting, high temperature, not easy to process the casting, can be used in the melt mold precision casting casting.
