Insulating Sleeves Direct Pouring Type :
                                                                        These are Insulating type of sleeves available in various standard sizes. These sleeves have been provided with a seat in inside bottom portion to accommodate a foam filter. These sleeves are placed directly on the body of the casting or sidewise and metal is directly poured in the sleeve. After filling out the mold and the sleeve, the filter floats out and the liquid metal inside the sleeve starts feeding the casting. This can achieve a perfect “Directional Solidification” in the casting. This also eliminates the need for sprue, runner and ingates ( conventional gating system) hence improving the yield of castings 
We are one of the leading manufacturers of insulating sleeves in india.
