Exothermic Sleeves Open Type - INSULEX - 80 :
                                                            Highly exothermic cum insulating sleeves which can be used for steel, ductile and cast iron and copper base alloy castings except Alu. Bronze castings.   Being insulating also in nature, there is no initial chilling effect on liquid metal. Highly exothermic nature offers high value of M.E.F. This reduces the size of riser required drastically. Sleeves are available in open and blind types in size range from 1.5 inch to 12.00 inches diameter. We are one of the leading manufacturers of exothermic sleeves in india.

Why to use Exothermic Sleeves ?

• 50 % to 60 % savings in riser metal as compared to sand risers.

High M.E.F. value (1.65 Min.) allows much smaller risers compared to other local branded sleeves. Hence reduces cutting and fettling costs appreciablly.
Big expenditure on repairing of castings by welding after riser cutting is eliminated.

Gives high casting yields and reduces production cost.

• Reduces rejections due to shrinkages effectively reducing production cost.

Notes: 1. Bottom surface of riser is taken as cooling surface area.
2. Full height of sleeve is considered in calculating the volume of metal in the sleeve.
