Application Effect：

1.Reduce the weight of riser: saves metal and reduces energy consumption；

2.Improve the process yield: the use of efficient Insulation-fever riser, casting process can make the technological yield from 40% to 50-75%;

3.Improve production efficiency；

4.Reduce the workload of cutting riser: the use of heat-insulated risers reduces riser size, making risers easier to cut;

5.Reduce the riser height, save the sand;
