Riser stalk for low-pressure die casting

Silicon nitride(Si3N4) riser tubes have several varieties, mainly including reaction-bonded silicon nitride(RBSN), gas pressure high temperature sintering silicon nitride(GPSSN), etc. The riser tubes have all the characteristics of silicon nitride, such as, good thermal resistance, corrosion resistance, high temperature resistance and long lifetime. The sintering temperature of GPSSN is higher than RBSN, so its density is higher and porosity is lower. And its intensity and resistance to corrosion performance is much better which makes the lifetime is longer.


1. High strength at high temperatures, high hardness
2. High toughness
3. High corrosion resistance when mixed with molten nonferrous metal
4. Anti-chemicals
5. Electrical isolation


As a pipe of transmitting the liquid aluminum for the automobile hub casting, the Silicon Nitride Riser Tube is widely used in the aluminum smelting industry, petroleum chemical industry, ceramic industry and electronics industry.
