Type-G Blind Feeder Exothermic Insulation Riser Sleeve

The G-type exothermic riser is a riser sleeve made of heat-insulating materials and heat-generating materials. It is a fluorious free, high exothermic performance, high feeding efficiency, high compressive strength, and maximized castings yields, which is used cooperatively with guide rods. Easy to use, and reduced the contact area with castings. It is easy to remove from castings, and applied to high pressure sand molding line.

Use Principle:

The reaction of the heating material generates heat and reduces the heat loss of the insulating material, thereby increasing the temperature of the molten metal in the riser sleeve, prolonging the solidification time of the molten metal in the riser sleeve, and realizing the feeding of the riser sleeve to the casting, effectively improving the ability to feed.

Riser Sleeve Advantages:

1. Effectively solve defects such as shrinkage porosity and shrinkage of castings, and increase the density of castings.

2. Obviously, reduce defects such as slag inclusion and pores in castings;

3. Significantly improve the feeding efficiency of the riser and the production rate of castings;

4. Reduce riser cleaning cost and welding repair workload.
