Chinese Lost wax process originated from Burning Loss method which can be dated back to the middle and the late periods of Shang Dynasty. The Burning Loss method started dying off after the development of Lost wax process.

Lost wax process is a precesion casting process used to cast ware which is made of brozen and other materials.

The process is that engineers should make a mold which is made of beewax, then the lame core and outside parts will be made from other fire-proof materials. With the heating process,the whole wax pattern will be melted, running away. So the whole casting mold will be empty. The engineers will pour molten metal into mold, then get a casting..

The advantages of lost wax process:

1. The castings significant feature of high precision and high finishi. The dimensional precision can reach to 5% of nominal size. And the roughness level is Ra0.8-3.2μm， which can help us prove the efficiency of machining.

2. The mechanical properties of the castings produced by Lost wax process are superior, and the costs are lower.

3. Comprehensive material adaptability.

4. Good production flexibility. Lost wax process is suitable for mass production,small-lot production, even the unit production.
