The riser sleeve is characterized by a plurality of cavities (102) are formed on the side wall, extending from the top in an axial direction of the body. These cavities provide air gaps when the riser sleeve is inserted into a mold, decreasing heat loss at the interface between the riser sleeve and the mold.
