Reliable Performance
Engineered for dependable feeding performance throughout the casting process.
Exothermic feeding solution
Neck Down Exothermic Sleeves
These sleeves are available in various sizes ranging from 1” to 7” diameter and a maximum height of 8”. Sleeves are available in open and blind categories.
Key advantages
- Highly exothermic in nature, MEF (1.6)
- Also insulating in nature and do not cause initial chill of metal in the sleeves
- High feeding efficiency
- Helps reduce rejections and improve casting yield

- Bottom surface of the sleeve riser is taken as cooling surface.
- Full height of the sleeve is considered in calculating the volume of metal in the sleeve.
- Dimensions given above are nominal. Tolerance of 2 mm in diameter and height may occur.
