Insulating Riser Sleeves

Our insulating sleeves are vacuum formed and are engineered for efficient and effective feeding of castings. Every insulating sleeve offers durability during handling, textured outside surfaces permitting key-in to sand, no sand contamination at shake-out, minimum gas, no smoke, and no metal penetration, allowing a clean strip of the riser from the mold. Insulating sleeves range from 1” up to 30″ diameter and come in 6″, 8″, 10″ or 12″ lengths.
