Precision forging process of casting is refers to the use of wax model, wrapped in a layer of clay refractory material in their appearance, heated to melt the wax out, thusformed by the refractory material of the shell, and the metal is melted and poured into the shell, the metal cooled refractory metal mould
Member, process called precision forging the metal processing, also known as themelt die forging forging or lost wax.
These designs with ordinary precision forging process are hard to make out, but thelost wax method with precision forging process, characters can use paraffin no strength, easy to carve, with ordinary tools can carve out and to get the tomb of Ceng Houyi statue like paraffin wax material handicrafts,
Then additional gating system, coating, dewaxing, pouring, can get the tomb of Ceng Houyi statue exquisitely. In the metal jewelry and many non metal handicraftmanufacturing, using this method is also has a long history, still is the main method ofa lot of jewelry and crafts production.
This method of ancient already had, in the far hundreds of years BC, ancient Chinese people to create this kind of lost wax precision forging technology, used for precision forging with a variety of patterns and fine words of tripod and vessels products. The tomb of Ceng Houyi statue base for many mutual ring
Around the entanglement of long, end to end, staggered up and down, multilayermoire pattern forming a hollow in the middle. According to experts, China’s Shang Dynasty bronzes unearthed from the tomb of Ceng Houyi and the age of the first diskwill use this very ingenious technology.
