Innovation of guide wheel casting process

In the casting process of the guide wheel, a low-pressure casting process was used, which is conducive to the filling and shrinkage compensation of the molten metal. However, due to the thin tip of the blade, the filling capacity is required to be high, so the sand core forming method was selected. By using the core-type parting process, the contour clarity of the blade part and the density of the internal structure were successfully solved.
