Neckdown & CONE RISER Sleeves

Neckdown Risers

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. After the exothermic reaction is complete, the burnt sleeve essentially becomes an insulator, being continuously effective in minimizing heat loss. Exochem also offers an exothermic sleeve for manganese steel. These exothermic sleeves can be custom made with I.D.'s ranging up to 30” – consult your local Exochem distributor for more information.
