Riser Sleeves

Exothermic

Exochem exothermic sleeves are vacuum formed for iron and steel castings. Exochem sleeves are manufactured with quality materials and engineered for maximum performance and safety with minimum risk. Exochem offers three levels of exothermic riser sleeves; a mild exothermic sleeve for when the metal needs to stay liquid longer, and a high exothermic product that adds heat to the metal for better feeding efficiency. Exochem also offers an exothermic sleeve for manganese steel. These exothermic sleeves can be custom made with I.D.'s ranging up to 30”.

Insulating

Exochem insulating sleeves are vacuum formed and are engineered for efficient and effective feeding of castings. Every Exochem 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.

When placing your order, please specify ID, length, and whether standard, insulating or exothermic materials. Consult your local Exochem distributor for more information.
