The Function of Foundry Riser Sleeves:

The function of setting the riser sleeves during casting is reflected in the following: the foundry riser sleeve is the cavity used to store the metal liquid on the mold. It is designed to improve the quality of castings. The setting of the riser sleeve is a casting process measure taken to prevent the shrinkage of the casting. The riser sleeve is mostly used for alloys with large shrinkage and easy to form shrinkage holes, such as cast steel, aluminum-silicon alloy, and ductile iron.
