There is a high temperature alloy castings, it belongs to the high complexity of the flat products, it is generally the mode of preparation it is not enough to molding, new research methods in this case becomes imperative. Currently, this also depends on good results.

In order to prepare high quality of the complexity of the flat type high temperature alloy castings, the first ceramic core to be prepared, and placed in a mold prepared wax pattern; and positioning the ceramic cores, the combination of wax; but also the a series of wax coating process, dewaxing, roasting; be carried out after the completion of packing, pouring, and finally casting off the core desired.
In order to adapt to the high temperature alloy castings increasingly complex structure, quality lightweight parts of the demand, the emergence of this technology is of great significance, it is this aspect which fills the technology gaps, create more economic and social benefits。
