Reliable Performance
Engineered for dependable feeding performance throughout the casting process.
Insulating feeding solution
Neck Down Insulating Sleeves
Neck down insulating sleeves are available in multiple sizes to support efficient feeding and easier riser removal.
Key advantages
- Highly insulating materials prevent initial chilling of metal in the sleeve
- High MEF up to 1.45
- Helps reduce casting rejection and required riser size
- High feeding efficiency
Neck Down Sleeves
These sleeves are available in open, blind & Direct pour types & range in sizes from 1”dia to 7” dia for open & 40mm to 80mm in dia for blind sleeves Direct pour sleeves are available in 40,50,60,70 & 90 mm dia with foam filters.
Advantages
1. Highly insulating nature of materials used ensures no initial chilling of metal in the sleeves.
2. High MEF – up to 1.45
3. Application of these sleeves reduces the cost of casting by way of reducing rejections & also reducing the riser sizes required.
4. High feeding efficiency.
Improved Yield
Helps reduce riser volume, metal consumption and overall casting costs.
Flexible Sizing
Available in standard configurations with custom sizes offered on request.

- 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.
