Exothermic Sleeves

 

  • Highly exothermic cum insulating sleeves can be used for steel, ductile and cast iron and copper base alloy castings except Alu. Bronze castings.
  • Exothermic sleeves are also insulating in nature, hence there is no initial chilling effect on liquid metal.
  • Highly exothermic nature offers high value of M.E.F. thus reducing the size of riser required drastically.
  • Exothermic sleeves are available in open and blind types in size range from 1.5 to 6.0 inches in diameter.
