dewaxing casting is now called precision casting. It is a small or no cutting casting process. It is an excellent technology in the foundry industry. It is widely used. It is not only suitable for the casting of various types and all kinds of alloys, but also the size accuracy of the castings, the surface quality is higher than the other casting methods, and even the other casting methods are difficult to cast, and the casting can be cast by precision casting.

    investment casting was developed on the basis of wax pattern casting in ancient times. As an ancient country of civilization, China is one of the countries that use this technology earlier. In the hundreds of years BC, the ancient laboring people of our country created this kind of lost wax casting technology to cast products with various fine patterns and words, such as the Zeng Hou B Tomb of Zeng Hou during the spring and Autumn period. The pedestal of Ceng Houyi’s tomb is a number of intertwined dragons. They are connected in the first place and are interlaced up and down to form a multi-layer moire pattern in the middle. These patterns are difficult to be made by ordinary casting. And the wax loss casting process can make use of the characteristics of the paraffin without strength and engraving, with ordinary tools. In order to carve the paraffin material that is the same as that of the Ceng Houyi tomb, and then add the casting system, paint, dewaxing, pouring, you can get the beautiful Ceng Houyi tomb.

    modern investment casting method was applied in industrial production in 1940s. At that time, the development of aero jet engine required the manufacture of heat-resistant alloy parts, such as blades, impellers, nozzles and so on. Because the heat resistant alloy material is difficult to be machined, the shape of the parts is complicated, so it can not or cannot be made by other methods. Therefore, it is necessary to find a new precise forming process. An important development has been achieved on the basis of this. Therefore, the development of the aviation industry has promoted the application of the melt mold casting, and the continuous improvement and perfection of the mold casting have also created favorable conditions for the further improvement of the performance of the aviation industry.
