Product Function
Risers are elements of the gating and feeding system which are intended for displacing shrinkage cavity and porosity outside the casting.
Feeding By Heat Insulating
By using insulating Riser material one can achieve effective rise ring and directional solidification for permanent mould Gravity Die Casting of Aluminium - Silicon alloys.
Most satisfactory results can be achieved by using Ceral Riser Sleeve as heat insulating material for Riser
Ceral Riser Sleeves
Through our continuous research, we have developed and standardized two grades of Ceral Riser Sleeves : Ceral HI 93, Ceral HI 142 respectively having very high and moderately high insulating property.
These are suitable grades for efficient heat insulation at Riser and hence directional solidification can be achieved.
Typical Properties Of Ceral Regular
| Sr. No | Grade | Thermal Conductivity At 800°C W/mK | Heat Transfer Coefficient BTU/h Ft2°F | C.C.S.(kg/cm2) |
|---|---|---|---|---|
| 1 | Ceral HI 142 | 0.38 to 0.40 | 2.65 to 2.85 | 45 - 50 |
| 2 | Ceral HI 131 | 0.44 to 0.46 | 3.05 to 3.25 | 105 – 115 |
