These are Insulating type of sleeves with top end of sleeve blind and having Williams Notch inside the sleeve to aid the riser puncture on the top so that it can feed the casting to its maximum capacity.

Highly insulating sleeves which can be used for steel, ductile and cast iron and copper base alloy castings. Being highly insulating in nature, there is no initial chilling effect on liquid metal. Highly porous structure and low density of sleeve 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

• 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.

Why to Use Insulating Sleeves ?

• 30 % to 50 % savings in riser metal as compared to sand risers.
• High M.E.F. value (1.50 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.
• High volume feeding efficiency.
• Reduces rejections due to shrinkages effectively reducing production cost.
• Being purely insulating in nature, it does not contaminate the metal.
• Does not cause contamination of metal.

• These insulating sleeves are available in various standard sizes.
• Direct pour sleeves are provided with a seat inside the bottom portion to accommodate a foam filter, these sleeves are placed directly on the body of casting or at the side and metal is directly poured in the sleeve. After filling out the mold and the sleeve, the filter floats out and liquid metal inside the sleeve starts feeding the casting. This can achieve a perfect Directional Solidification in the casting.
• This eliminates the need for sprue, runner and ingates (conventional gating system), hence improving the yield of castings.
