Superalloy is a very special material, if it is cast as a raw material, I do not know whether the time of casting and casting difficulty will increase. With this question we have to ask the experts in this field, the result is this.

Including more types of high-temperature alloys, titanium alloy as an example we want to perfect production molding is very difficult. Although the casting process and the ordinary experienced the same, but the requirements will be more stringent, such as mold design, usually you have to constantly change the size, and only after an appropriate adjustment to the shrinkage in order to enter the next link.
Wax mold is made of a step, this step can be repeated several times to complete, but not anxious. Wherein any one process can not be sloppy, once the error has been obtained by casting products is likely to be unacceptable. In addition, for each grasp of all aspects of environmental parameters it is also crucial, so the general high temperature alloy castings products will allow a certain tolerance.
