  • Description

EXOTHERMIC SLEEVES facilitate effective feeding of metal due to their unique design, thereby extending the solidification time of risers used on castings. The design of our Exothermic sleeves initiate exothermic reaction in the riser which liberates heat. Heat in the riser is conserved over an extended period as the Insulating sleeves provide an efficient thermal insulating layer.
Our sleeves provide strong and durable resistant to pressures generated during ramming of sand in the foundries as they are vacuum molded and their composition is carefully formulated from high grade insulation / exothermic materials bonded with organic and inorganic binders.
Function : An exothermic reaction is a chemical reaction that is accompanied by the release of heat. It gives out energy to its surroundings. The energy needed for the reaction to occur is less than the total energy released. During the pouring of mould, an exothermic reaction sets in as molten metal fills an exothermic sleeve riser. It is possible to reduce the riser size considerably as compared to sand riser system as the exothermic reaction helps in maintaining the riser metal temperature over an extended period of time.
Yield: Use of Exothermic sleeves enables improving the yield by more than 30%

BENEFITS :  Permits use of substantially reduced riser size without compromising on quality. Cost savings due to high foundry yields. Significant saving in energy and costly foundry inputs due to minimization of feed metal. Higher productivity.
